## Access Class 7 Science Chapter 7 - Weather, Climate and Adaptations to Climate Notes

• Weather is the day-to-day state of the atmosphere at a location, which is influenced by factors such as humidity, temperature, wind speed, and so on.

• Humidity: It is the amount of water vapour present in the atmosphere, and which is measured by a tool called a hygrometer.

• Climate refers to the average weather conditions at a given location over a period of time.

• Climate-Altering Factor:

1. The shape of the land is referred to as topography.

2. Sea Level: One of the key aspects that affect a region's climate is its distance from the sea and neighbouring water bodies.

3. Ocean Currents: Ocean currents can carry heat from land to sea or vice versa, impacting the region's temperature.

4. While all of the above are natural factors, we, humans, are one of the most damaging factors that have triggered this climate change.

• Adaptations to Climate: Adaptations are characteristics and behaviours that assist animals in surviving in a certain environment.

• Adaptation has Led to the Classification of Three Regions:

1. Polar Areas: The climate in the Polar Regions is harsh. For six months, the sun does not rise at the poles, and for another six months, it does not set.

2. Tropical Rainforest: The tropical rainforest has torrid summers and a lot of rain. Throughout the year, the days and nights are about equal in length.

3. Desert: This region has a harsh climate. Rainfall is low, and there is a lot of sunlight.

• ### Migration

1. It is the vast movement of animals, especially birds, from colder to warmer regions to avoid the cold, breed, or because of food scarcity.

2. During the day, birds are guided by the sun, while at night, they are guided by the stars. Every year, a Siberian crane migrates from Siberia to India.

We provide the students with weather climate and adaptation of animals to climate class 7 notes in PDF format, which can be downloaded easily. This makes the offline study process for students easier by giving them the liberty to study at their own pace and comfort. The students can also get the study material printed in case they are planning to opt for group studies with their friends or are not comfortable studying online.

### Weather and Climate Class 7 Revision Notes

Weather

Weather is defined as the atmospheric condition of any place regularly and is determined by various factors, including humidity, temperature, wind speed, etc.

### Conditions Affecting Weather

The weather of any place is determined based on several factors, which include:

• Temperature

• Humidity

• Wind or atmospheric pressure

• Precipitation

• Cloudiness

• Visibility of horizon.

• Separation of air masses.

### Climate

Climate is defined as the weather of an area over a prolonged period, considered 20 years. For e.g., If the temperature of any region is usually cold, we consider it a cold place.

Various factors, including altitude, geography, topography, etc., affect the climate of any place.

## Difference Between Weather and Climate - Table will be updated soon.

### Clouds

The process of cloud formation is called convection.

The Process of Cloud Formation Goes as Follows:

• The warm air above the ground becomes lighter with the sunlight and is carried upwards. When the air rises higher, the temperature drops leading to the formation of water vapours.

• This is followed by water vapour condensation and cloud formation, which is formed by billions of tiny water droplets.

### Rain Gauge

It is an important instrument used for the measurement of rainfall. It is in the form of a measuring cylinder which has a funnel on the top to collect rainwater.

Polar Regions:

• These regions have extreme cold climatic conditions.

• The majority of the year, these regions are covered in snow.

• In these regions, the temperature can reach as low as -37℃.

• The Arctic region is called North Polar, while the Antarctic region is called the South Polar.

• The animals living in these regions have to adapt to these conditions.

### Tropical Rainforests:

• These regions usually have a high temperature as they are located around the equator.

• In winters, the temperatures are usually above 15℃, while in summers, the temperatures go over 40℃.

### Desert:

• These regions have extremely hot climates and receive less amount of sunlight.

• The animals have to usually adapt to all the conditions based on several climatic conditions.

• For example, In Polar regions, the polar bears have white fur. It is due to the white fur that bears are protected from their predators.

• The polar bears have a layer of fat under their skin, which protects them from the chilly environment.

• This is the case in different regions across the globe.

## FAQs on Weather, Climate and Adaptations of Animals to Climate Class 7 Notes CBSE Science Chapter 7 (Free PDF Download) (Not in the Current Syllabus)

1. What is Humidity?

Ans: Humidity is defined as the amount of water vapour present in the atmosphere. The more the amount of water vapour, the higher is the humidity, which leads to an increase in moisture. When the amount of water vapour is less, it feels dry. The measure of humidity is in the form of a percentage (%). 100% humidity means complete air saturation.

2. What are the Maximum and Minimum Temperatures?

Ans: The highest temperature recorded throughout the day in any region is defined as the maximum temperature. While the lowest temperature recorded throughout the day is defined as the minimum temperature. There is a special thermometer called maximum-and-minimum thermometer, which is used to record temperatures throughout the day.

3. What is Weather Forecasting and Weather Reports?

Ans: Many weather experts often rely on weather forecasting. The prediction of weather conditions in advance is defined as weather forecasting. The weather reports are also prepared, which contain all the information regarding temperatures, rainfall, and other atmospheric conditions in the past several hours.
