Land, Soil, Water, Natural Vegetation and WildLife Resources Class 8 Notes Geography Chapter 2 - PDF Download
Class 8 Geography Chapter 2 Notes talks about how different natural resources impact our human lives. We are surrounded by various natural resources including land, soil, water etc. All these resources differ in variety from region to region. These resources determine our lifestyles to a large extent. You may be living in a thickly populated area, but there are regions which are sparsely populated or uninhabited.
To learn more about topics such as land, soil, water, natural vegetation, and wildlife resources, students can study Chapter 2 of Geography. The Class 8 Geography Chapter 2 notes will provide deep insights on various natural resources including land, soil, natural vegetation, and wildlife resources. Students should also properly go through NCERT Class 8 Geography Chapter 2 notes for complete preparation for the exams.
Class 8 Social Science (Geography) Chapter 2 – Land, Soil, Water, Natural Vegetation, and Wildlife Resources - Brief Summary
It is a known fact that 90% of the world population inhabits only 30% of the available land area. The remaining 70% of the land is either uninhabited or sparsely populated. Land, soil, and water are the abiotic resources of the earth. They also comprise the most important resources. Biotic resources are composed of natural vegetation and wildlife resources. Both Biotic and abiotic resources are exhaustible in nature. Hence, humans should practise judicious use of these resources to enhance their longevity and sustainability.
Land is considered the most important natural resource. It covers about 30% of the total area of the earth’s surface. The world population occupied land in an uneven manner. This pattern of inhabiting land is due to various factors, such as land and climate, water fertility of the soil, etc. Sparsely populated or uninhabited areas resist more population because of the rugged topsoil present there. This chapter also discusses in-depth the various uses of land, conservation of land resources, soil, soil formation, factors affecting soil formation, degradation and conservation of soil, water, the problem of water availability and conservation of water, natural vegetation and wildlife, its distribution and conservation.

1. What are different methods for soil conversation?
Some of the methods for soil conservation are:
Mulching: It refers to covering the bare ground which gets directly exposed to weather conditions with a layer of organic matter like straw.
Contour Barrier: These are contour strips which are made to slow down water movement.
Rock Dam: A pile of rocks is made to stand in the way of water to slow down its flow.
Terrace Farming: Wide strips or terraces are made on steep slopes to grow crops and support vegetation.
Intercropping: To prevent the soil from rain wash, different crops are grown in alternate rows at different times of the year.
Contour Ploughing: this farming practice involves planting and ploughing at the elevation contour lines of the slope.
Shelterbelts: It refers to planting belts or rows of plants or trees to prevent soil cover from high winds.
2. What are the different uses of land?
There are various purposes of which land is used, including agriculture, forestry, constructions etc. The land use pattern is highly dependent on two factors, which are:
Physical Factors: These factors encompass topography, climate, minerals and availability of water. These are the key determinant factors when it comes to land use.
Human Factors: Factors like populations density and technological development determine to a large extent the land use pattern.
Apart from this, land can be broadly classified into private land, community land and based on ownership.
3. What do you know about different types of natural resources such as land, soil, water, natural vegetation and wildlife resources?
Land, soil Water, natural vegetation, and wildlife are all-natural resources. We need land for building houses and industries. We use soil for growing crops. Land could be used for growing crops and for constructing buildings. Natural vegetation includes shrubs, herbs, and trees. Wildlife includes all the animals found on the earth. Animals such as cows, goats, and sheep are useful for human beings because a man gets various products from these animals.
4. What is conservation of natural vegetation Class 8?
Conservation of natural vegetation includes protecting and preventing trees and plants for future use. Trees are very useful for living beings. Living beings cannot live without trees. Trees and plants give us oxygen. They not only give us oxygen but also give us other useful products such as timber for making furniture. We also get medicines, fruits, paper, and rubber from plants. Thus, the conservation of natural vegetation is important for the next generation.
5. What are the two types of land Class 8?
Land is an important resource that is used for agriculture and constructing buildings. About 30% of the Earth's surface is covered by land. But, the entire land available on the earth is not habitable. The land has different characteristics and climates. Some areas are sparsely populated due to rugged topography, steep slopes, and low-lying areas. Areas that are highly populated include plains, availability of water, and fertile soil for agriculture.
6. What is land and what is the concept of land use Class 8?
Land is a natural resource and it is used for different purposes. Fertile land is used for agriculture and growing crops. Infertile land is not suitable for agriculture and therefore areas having infertile land and scarcity of water are sparsely populated. Fertile land with easy availability of water and other natural resources is thickly populated. People inhabit the areas where plain land is available because it is easy to plan land for building houses and industries. A land with rugged topography is not suitable for living.
7. What is land degradation and how does it occur?
Land degradation means the quality of land decreases due to different activities. Land degradation may occur due to several reasons. The main causes of land degradation include deforestation or excessive cutting of the trees, absence of rain also makes the land infertile for agriculture, harsh climatic conditions, the poor utility of land, overgrazing by animals, etc. In the past years, land degradation has occurred rapidly and this has affected the environment.
