Science Class 7 - Weather Climate-And-Adaptations-Of-Animals-To-Climate Notes

Weather, Climate and Adaptations of Animals to Climate

Welcome to the chapter on Weather, Climate and Adaptations of Animals to Climate for Class 7. In this chapter, you will learn about the difference between weather and climate, how weather changes, and how animals adapt to different climates. By the end of this chapter, you will understand why some animals live in hot places, some in cold places, and how their bodies help them survive!

Introduction

Weather and climate affect everything around us. Animals have special features that help them live in their surroundings. Let’s explore how weather and climate work and how animals adapt!

What is Weather?

Weather is the condition of the atmosphere at a particular place and time. It can change daily and includes temperature, rainfall, wind, and humidity.

• Sunny, rainy, windy, cloudy, or snowy days are all types of weather.
• Weather can change quickly.

What is Climate?

Climate is the average weather condition of a place over a long period of time. It tells us what kind of weather is common in a region.

• Deserts have a hot and dry climate.
• Polar regions have a cold climate.
• Rainforests have a wet and warm climate.

Difference Between Weather and Climate

• Weather changes every day; climate stays the same for many years.
• Weather is what you see outside today; climate is what you expect for a place.

Adaptations of Animals to Climate

Animals have special features or behaviors that help them live in their climate. These are called adaptations.

Adaptations in Hot Climates

• Camels have thick skin and can store water to survive in deserts.
• Fennec foxes have large ears to lose heat.

Adaptations in Cold Climates

• Polar bears have thick fur and fat to keep warm.
• Penguins have a layer of fat and huddle together for warmth.

Adaptations in Rainy Climates

• Frogs have slippery skin to live in wet places.
• Monkeys have strong arms to swing from trees in rainforests.

Fun Activity: Adaptation Detective!

Pick an animal and find out how it survives in its climate. Draw the animal and label its special features!

Summary

• Weather changes daily; climate is the usual weather of a place.
• Animals have adaptations to survive in their climate.
• Adaptations help animals live, find food, and stay safe.

Practice Questions

1. What is the difference between weather and climate?
2. Name one adaptation of a camel.
3. How do polar bears stay warm?
4. What kind of climate do rainforests have?
5. Why do animals need adaptations?

Challenge Yourself

• List three animals and describe their adaptations to climate.
• Draw a scene showing animals in different climates.

Did You Know?

• Some birds migrate to warmer places when the climate gets too cold!
• Cacti store water in their stems to survive in deserts.

Glossary

• Weather: The condition of the air outside at a certain time.
• Climate: The usual weather of a place over many years.
• Adaptation: A special feature or behavior that helps an animal survive.

Answers to Practice Questions

1. Weather changes daily; climate is the average weather over years.
2. Camels store water in their bodies.
3. Polar bears have thick fur and fat.
4. Rainforests have a wet and warm climate.
5. To survive in their surroundings.
