1. What shapes the Earth’s surface?
Answer:
The Earth’s surface is constantly shaped and reshaped by internal and external forces.
Internal forces originate inside the Earth. These include earthquakes, volcanic eruptions, folding, and faulting. They create features such as mountains, valleys, volcanoes, and ocean basins.
External forces act on the Earth’s surface through processes such as weathering, erosion, transportation, and deposition.
The major agents that reshape the surface are running water, waves and tides, glaciers, wind, and underground water.
The movement of tectonic plates also plays an important role in forming mountains, volcanoes, continents, and ocean basins.
Thus, the combined action of forces from within and on the surface of the Earth continuously creates and modifies different landforms.
2. What is plate tectonics? What are the effects of plate movement?
Answer:
Plate tectonics is a theory that explains the movement of the Earth’s crust. According to this theory, the outer layer of the Earth is broken into many large and small pieces called tectonic plates. These plates move slowly over the semi-molten layer below them.
There are three main types of plate movement:
Convergent boundary – Two plates move towards each other. This can form fold mountains like the Himalaya and can also cause earthquakes and volcanic activity.
Divergent boundary – Two plates move away from each other. Magma rises and forms new crust, creating features like mid-ocean ridges.
Transform boundary – Two plates slide past each other. This movement mainly causes earthquakes.
Plate movement can form mountains, valleys, ocean basins, and volcanoes. It can also cause earthquakes and volcanic eruptions.
3. How are landforms formed and how are they classified?
Answer:
Landforms are natural features on the Earth’s surface. They are formed slowly over time by both internal and external forces. Internal forces such as uplift, folding, and faulting create major landforms, while external forces such as erosion and deposition reshape them.
Landforms are mainly classified into three types: mountains, plateaus, and plains.
Mountains are high and steep, plateaus are raised areas with flat tops, and plains are wide and mostly level, low-lying areas. Other landforms such as valleys, deltas, beaches, deserts, and islands are also formed by different natural processes.
4. How are humans and other living beings connected to these landforms?
Answer:
Humans and other living beings are closely connected to landforms because landforms affect water, farming, settlements, transport, jobs, ecosystems, and culture.
Some important connections are:
River valleys and meanders provide fertile soil for farming and support irrigation and settlements.
Deltas have fertile soil and support farming, fishing, trade, and aquatic life.
Glaciers provide fresh water and feed rivers.
Beaches and coastal areas support fishing, tourism, and recreation.
Waterfalls attract tourists and can be used to produce hydroelectric power.
Therefore, landforms play an important role in the life and activities of humans and other living beings.
5. How do disasters associated with different landforms impact human lives?
Disasters linked to different landforms can seriously affect human life. Earthquakes and volcanic eruptions are common in tectonically active areas, while landslides and avalanches mostly occur in mountainous regions.
These disasters can cause loss of life, damage to houses, roads, bridges and crops, and disruption of transport and daily activities. They can also affect livelihoods and damage the environment. Proper planning, safety measures and disaster preparedness can help reduce their impact.
Let’s Explore
1. Examine the plate map Fig. A (below) with the earthquake and volcano map Fig. B (below). What correlation do you observe?
A.
B.
Answer:
Earthquakes and volcanoes are closely related to tectonic plate boundaries. Most of them occur near the edges of plates, where the plates collide, separate, or slide past each other.
The Ring of Fire around the Pacific Ocean is a good example. This region has many active volcanoes and frequent earthquakes because several tectonic plates meet there.
This pattern shows that the movement of tectonic plates is one of the main reasons for earthquakes and volcanic eruptions around the world.
2. Observe the map showing the distribution of earthquakes and volcanoes Fig. b. Can you identify which continents and countries are located around the Ring of Fire with the help of an atlas or a globe?
B.
Answer:
The Ring of Fire is a large zone around the Pacific Ocean where many earthquakes and volcanic eruptions occur. It passes through parts of Asia, North America, South America, and Oceania.
Some important countries located along the Ring of Fire are:
Japan
Indonesia
Philippines
New Zealand
Papua New Guinea
Russia (eastern region)
United States of America (Alaska and western coast)
Canada
Mexico
Guatemala
Chile
Peru
Ecuador
These regions experience frequent earthquakes and volcanic activity because they lie near tectonic plate boundaries.
3. Does India have a risk of earthquakes? Can you find out which region is more vulnerable to earthquakes? Why do you think human lives are at risk?
Answer:
Yes, India is vulnerable to earthquakes. This is because the Indian Plate is moving towards the Eurasian Plate. Their movement has formed the Himalayas and also causes earthquakes in many parts of India.
The main earthquake-prone areas in India are:
The Himalayan region – Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, and Arunachal Pradesh
North-Eastern states
Kutch region of Gujarat
Parts of Bihar
Andaman and Nicobar Islands
These areas are more likely to experience earthquakes because they are close to active fault lines and plate boundaries.
Earthquakes can be dangerous because strong shaking may damage or collapse buildings, roads, bridges, and other structures. People may get trapped under debris.
Earthquakes can also cause landslides, fires, and damage to transport and communication systems.
Therefore, earthquake-resistant buildings and proper disaster preparedness are important to reduce the loss of life and property.
4. Look carefully at this photograph and answer the following questions:
(a) What do you think caused this situation?
(b) What could that grey powder be?
(c) What does it tell us about the Earth’s internal forces?
Answer:
(a) This situation was most likely caused by a volcanic eruption. The eruption released ash and other volcanic materials, which spread over the nearby area and covered houses, trees, and roads.
(b) The grey powder is volcanic ash. It is made up of very small particles of rock, minerals, and volcanic glass that are thrown into the air during an eruption and later settle on the ground.
(c) The photograph shows that powerful forces are active inside the Earth. Heat and pressure inside the Earth can push magma, gases, and ash to the surface through volcanic eruptions. These forces can change the landscape, form new landforms, and sometimes cause serious damage to human settlements.
5. Observe the photographs Figs. (a & b) and also note the types of erosion. How are farmers affected by erosion due to water and wind?
Answer:
Farmers are greatly affected by soil erosion caused by water and wind because it removes the fertile top layer of soil needed for crops.
During heavy rain, flowing water can wash away the nutrient-rich topsoil. This lowers soil fertility and may also form small channels or deep gullies, making farming difficult.
In dry and open areas, strong winds can carry away loose soil particles. This reduces the soil’s fertility and its ability to hold moisture. Seeds and young plants may also get damaged or covered by sand and dust.
Because of soil erosion, farmers may get lower crop yields and may need to spend more on fertilisers and soil conservation. In severe cases, farmland can become less productive.
Therefore, water and wind erosion are serious problems for agriculture and can affect farmers' livelihoods.
6. Have you heard about the Sundarbans delta? Try and explore its uniqueness and find out why it is popular with tourists.
Answer:
The Sundarbans is the largest delta in the world. It is formed by the Ganga, Brahmaputra, and Meghna rivers before they enter the Bay of Bengal. The delta spreads across India and Bangladesh and is well known for its many rivers, creeks, and thick mangrove forests.
One of the main features of the Sundarbans is its mangrove vegetation, which is able to grow in salty and muddy water. The region is also famous for the Royal Bengal Tiger. Other animals found here include crocodiles, spotted deer, turtles, and many varieties of birds and fish. Because of its rich wildlife and ecological value, the Sundarbans is recognized as a UNESCO World Heritage Site.
The Sundarbans is also a popular tourist destination. Visitors come to enjoy its natural beauty, explore the mangrove forests, take boat rides through narrow waterways, go on wildlife safaris, and watch different species of birds. Tourists from many places visit the region to experience its unique ecosystem and see animals in their natural surroundings.
Therefore, the Sundarbans is not only an important delta but also one of the most unique and environmentally important regions in the world.
7. Observe the landforms around your school or residence and try to identify which agent may have created them.
Answer:
The landforms around my school or home include open fields, small raised areas, and a nearby stream. These features seem to have been shaped mainly by running water.
Over time, the stream may have eroded soil in some places and deposited sediments in others, creating higher and lower areas. Flat agricultural fields may also have formed from fertile soil deposited by rivers over many years.
In dry and sandy places, wind can also move and deposit fine soil particles. Therefore, running water is the main agent shaping the landforms in my locality, while wind may have caused smaller changes in some areas.
8. Complete the exercises given at the end of each type of disaster with the help of newspapers, atlases, and books. Make a list of disaster-prone areas from India and the world and enlist mitigation measures quoting recent examples.

Think About It
1. A devastating flood struck the Chamoli district in Uttarakhand in February 2021, in which many people and livestock lost their lives. There was severe damage to buildings, roads, bridges, and hydel projects; connectivity to villages was adversely affected. Can you find out the reasons that led to the sudden and unexpected flood?
Answer:
The Chamoli flood of February 2021 was a sudden and devastating disaster in Uttarakhand. It was mainly caused by the collapse of a huge mass of rock and ice from a mountain near the Ronti Glacier.
The rock and ice moved rapidly down the steep mountain slopes and entered the Rishiganga and Dhauliganga rivers, producing a powerful flash flood. Scientists believe that climate change, which is leading to glacier melting and making mountain slopes more unstable, may have played a role in the disaster.
The fragile Himalayan landscape and the presence of development projects in river valleys also contributed to the scale of the damage.
The Chamoli disaster shows the importance of careful development in the Himalayan region, regular monitoring of glaciers, effective early warning systems, and better disaster preparedness. These measures can help reduce the loss of life and property from similar disasters in the future.
Let’s Map
1. Pick any two plates from the map above and complete the table given below.
Answer:
Questions and Activities
1. What are the sources of energy that are required to cause movements associated with the internal forces of the Earth?
Answer:
The internal forces of the Earth mainly get their energy from two sources:
1. Heat from inside the Earth
The Earth’s interior contains a large amount of heat.
This heat creates convection currents in the mantle, which move the tectonic plates.
The movement of these plates can cause earthquakes, volcanic eruptions, folding, and faulting.
2. Radioactive decay of elements
Elements such as uranium, thorium, and potassium slowly break down deep inside the Earth.
This process continuously releases heat and helps maintain mantle convection over very long geological periods.
2. Relate various physiographic divisions you have studied in the earlier grades with various endogenic forces responsible for their origin.
Answer:
India’s major physiographic divisions were shaped by endogenic or internal forces in the following ways:
The Himalayas were formed when the Indo-Australian Plate collided with the Eurasian Plate. This collision pushed the land upward and created the young fold mountains.
The Northern Plains developed from sediments carried by rivers flowing from the Himalayas. Over time, these sediments filled the low-lying areas created by tectonic activity.
The Peninsular Plateau is one of the oldest landmasses in the world and is made up of ancient crystalline rocks. It was shaped by faulting and volcanic activity, including the formation of the Deccan Traps through large lava flows in the past.
The Coastal Plains and Islands were formed through a combination of tectonic movements and the action of sea waves over a long period of time.
3. Why and where do earthquakes occur frequently? Is it possible to predict earthquakes?
Answer:
Earthquakes mainly occur along tectonic plate boundaries, where plates move and interact with one another. When plates collide, move apart, or slide past each other, pressure builds up along faults. When this pressure is suddenly released, it produces seismic waves, which cause an earthquake.
Earthquakes are common along convergent boundaries, such as the Himalayan region, transform boundaries, such as the San Andreas Fault in California, and around the Pacific Ring of Fire.
India is also vulnerable to earthquakes, especially in the Himalayan region and the northeastern states. The 2001 Gujarat earthquake is one major example.
At present, scientists cannot accurately predict the exact time, place, and magnitude of an earthquake before it happens. They can identify earthquake-prone areas and monitor seismic activity, but exact short-term prediction is still difficult. Therefore, disaster preparedness and safety measures are more important than prediction.
4. “Plate movements are responsible for the distribution of earthquakes and volcanoes.” Explain.
Answer:
The theory of plate tectonics explains why earthquakes and volcanoes are mainly found in certain regions instead of being spread evenly across the world. Most of them occur along tectonic plate boundaries.
At convergent boundaries, two plates move towards each other. This creates strong pressure and can cause powerful earthquakes. If an oceanic plate moves below a continental plate, a process called subduction, magma may rise to the surface and cause volcanic eruptions.
At divergent boundaries, plates move away from each other. Magma rises through the gap, cools, and forms new crust. This process also creates volcanic features such as mid-ocean ridges, including the Mid-Atlantic Ridge.
At transform boundaries, plates slide past each other. Friction builds up between them, and when the stored stress is suddenly released, earthquakes occur. Volcanic activity is usually absent at these boundaries.
Therefore, most earthquakes and volcanoes are concentrated along plate boundaries.
The Ring of Fire is a belt around the edges of the Pacific Ocean. It is the world’s most active zone for earthquakes and volcanoes because several major tectonic plates meet along this region.
5. Draw and label a diagram of a meander and a delta
6. How are deforestation and erosion associated with each other? Explain.
Answer:
Deforestation and soil erosion are closely connected because trees help protect and hold the soil together. Tree roots keep the soil firm, while leaves reduce the direct impact of heavy rainfall.
When forests are cut down, the soil becomes loose and exposed to rain, wind, and flowing water. Heavy rainfall can wash away the fertile topsoil, while strong winds in dry areas can carry away loose soil particles. This reduces soil fertility, makes farming more difficult, and can lower crop production.
In hilly areas, deforestation can also increase the risk of landslides because there are fewer tree roots to hold the slopes together. Eroded soil may also enter rivers, causing siltation and increasing the risk of floods.
To control soil erosion, forests should be protected and more trees should be planted. Farming methods such as contour ploughing, terracing, and bunding can also help reduce soil loss.
Thus, deforestation increases soil erosion and can negatively affect agriculture, biodiversity, and the environment.
7. Develop a plan to protect the land in your local area from erosion.
Answer:
Plan to Protect Land from Erosion
Plant more trees and grasses to keep the soil firmly in place.
Avoid unnecessary cutting of trees.
Build proper drainage channels to prevent waterlogging.
Use contour farming and bunding in agricultural fields to reduce soil loss.
Control overgrazing by managing the movement of livestock.
Construct check dams in small streams to slow down flowing water.
Spread awareness among villagers and students about the importance of soil conservation.
Promote rainwater harvesting to reduce surface runoff.
Prevent illegal mining and uncontrolled construction that can damage the land.
Conduct regular tree plantation drives with the support of schools and local authorities.
These measures can help conserve soil, improve agricultural productivity, and protect the environment.
8. Which disasters do you think you might experience in your region? Discuss a mitigation plan in your classroom.
Answer:
As I live in Bihar, the region is mainly at risk of floods, earthquakes, heat waves, thunderstorms, lightning, and occasional droughts. During the monsoon season, some areas may also face riverbank erosion.
Mitigation Plan
Keep an emergency kit ready with food, water, medicines, a torch, and important documents.
Regularly check weather updates and official warnings.
Know the location of safe shelters and evacuation routes.
Take part in disaster preparedness drills at school.
Encourage the construction of earthquake-resistant buildings wherever possible.
During storms, stay away from weak buildings, trees, and electric poles.
Plant more trees to help reduce soil erosion.
Keep important emergency contact numbers easily available.
Support elderly people, children, and persons with disabilities during emergencies.
Create awareness in the community about disaster safety and preparedness.
Proper planning, awareness, and timely action can help reduce the loss of life and property during disasters.

Paint the limestone layers grey and the water features blue.
Label all the landforms clearly and neatly.
10. What precautionary measures will you take if you are staying in an earthquake-prone region?
Answer:
If I lived in an earthquake-prone area, I would take these precautions to stay safe:
Stay calm and avoid panicking.
Follow the “Drop, Cover, and Hold” method during the shaking.
Keep away from windows, mirrors, glass, and heavy furniture.
Keep an emergency kit ready with essential items.
Learn the nearest safe evacuation routes and emergency contact numbers.
Choose earthquake-resistant buildings whenever possible.
Switch off gas and electricity after the shaking stops, if it is safe to do so.
Do not use lifts during or immediately after an earthquake.
Once the tremors stop, move carefully to a safe open area.
Follow the safety instructions given by disaster management authorities.
11. Prepare a map showing landform-associated disasters that happened in the current calendar year.
12. Create a poster showing landforms that are considered to be sacred or important in your region, and add the folk stories associated with them.
13. Document a case of a disaster that hit your region in the past, highlighting its effects on various human activities.
Answer:
Case Study: The 2008 Kosi Flood in Bihar
The Kosi Flood of 2008 was one of the most serious floods that affected Bihar. In August 2008, an embankment of the Kosi River was breached near Kusaha in Nepal, causing the river to shift from its usual course. Floodwater spread across several districts of north Bihar, including Supaul, Madhepura, Saharsa, Araria, Purnia, and Katihar. A large number of people were affected, and many villages remained flooded for weeks.
The flood caused great hardship for local communities. Many people lost their homes and had to stay in relief camps. Shortages of food, clean drinking water, medicines, and proper shelter made the situation more difficult. Schools and colleges were also closed in many affected areas, disturbing the education of students.
Agriculture was badly affected. Standing crops were destroyed, and large areas of farmland were covered with sand and silt. This reduced the productivity of the soil and made farming difficult in some places. Many farmers also lost their main source of income.
The disaster damaged roads, bridges, railway lines, electricity systems, and communication networks. Transport was disrupted, which made rescue and relief work more challenging. Local markets and small businesses were also affected, leading to loss of trade and employment.
The flood also had environmental and health effects. Soil erosion, damage to riverbanks, waterlogging, and stagnant water became major problems. These conditions increased the risk of water-borne and mosquito-borne diseases.
The government, armed forces, and voluntary organisations carried out rescue and relief operations. They provided food, drinking water, medicines, temporary shelters, and medical support to affected people. Later, damaged houses, roads, and other facilities were gradually repaired and rebuilt.
The 2008 Kosi Flood showed the need for strong embankments, better flood forecasting, proper river management, disaster preparedness, and timely rescue operations. It also highlighted the importance of community cooperation in reducing the loss of life and property during floods.
14. Translate the given poster on landslides into your native language and display it in your home.
Answer:
Students can translate the given poster on landslides into their native language and display the translated poster at home.
15. Divide the class into three groups. Each group will work on one project (water, wind, and glacier). The project should highlight the causes, impact on human life and the environment, and mitigation measures.
Answer:
Students should complete the assigned project by researching the causes, impacts, and mitigation measures related to their chosen topic.
