Chapter 7 – Weather, Climate and Adaptations of Animals of Climate

Question 1

Name the elements that determine the weather of a place.


The temperature, humidity, rainfall, wind-speed, etc. are called the elements that determine the weather of a place.

Question 2

When are the maximum and minimum temperature likely to occur during the day?


The maximum temperature of the day occurs generally in the afternoon and the minimum temperature occurs in the early morning.

Question 3

Fill in the blanks

(i) The average weather taken over a long time is called __________

(ii) A place receives very little rainfall and the temperature is high throughout the year, the climate of that place will be ________ and _________

(iii) The two regions of the earth with extreme climatic conditions are __________ and ____________


(i) climate of the place (ii) hot, dry (iii) polar, tropical regions

Question 4

Indicate the type of climate of the following areas:

(a) Jammu and Kashmir:

(b) Kerala:,

(c) Rajasthan:

(d) North-east India:


(a) Jammu and Kashmir—moderately hot and moderately wet climate.

(b) Kerala—very hot and wet climate.

(c) Rajasthan—hot and dry climate.

(d) North-east India—The north eastern India receives rain for a major part of the year, hence wet climate.

Question 5

Which of the two changes frequently, weather or climate?



Question 6

Followings are some of the characteristics of animals:

(i) Diets heavy on fruits , (ii) White fur (iii) Need to migrate (iv) Loud voice

(v) Sticky pads on feet (vi) Layer of fat under skin

(vii) Wide and large paws (viii) Bright colours

(ix) Strong tails (x) Long and large beak

For each characteristic indicate whether it is adaptation for tropical rainforests or polar regions. Do you think that some of these characteristics can be adapted for both regions?

Question 7

The tropical rainforests has a large population of animals. Explain why it is so.


Because of continuous warmth and rain, the tropical region supports an enormous number and a wide variety of animals

Question 8

Explain with examples, why we find animals of certain kind living in particular climatic conditions.


Animals are adapted to survive in the conditions in which they live. Features and habits which help them to adapt to their surroundings are the result of evolution. So, to survive in a particular type of climate the animals must have certain adapted features. This is the reason we find animals of certain kind living in particular climatic conditions. For example, animals in the polar region are adapted to the extremely cold climate. They have special characteristics, such as white fur, strong sense of smell, a layer of fat under the skin, wide and large paws for swimming and walking in snow etc.

Question 9

How do elephants living in the tropical rainforests adapt themselves?


The elephant has adapted to the conditions of rainforest in many remarkable ways. It has a trunk that it uses as a nose because of this it has a strong sense of smell. The trunk is also used by it for picking up food. Its tusks are modified teeth. These can tear the bark of trees that an elephant loves to eat. So, the elephant is able to handle the competition for food very well. Large ears of the elephant help it to hear even very soft sounds. They also help the elephant to keep cool in the hot* humid climate of the rainforest.

Question 10

Choose the correct option which answers the following question:

A carnivore with stripes on its body moves very fast while catching its prey. It is likely to be found in:

(i) polar regions (ii) deserts

(iii) oceans (iv) tropical rainforests


(iv) tropical rainforests

Question 11

Which features adapt polar bears to live in extremely cold climate?

(i) A white fur, fat below skin, keen sense of smell.

(ii) Thin skin, large eyes, a white fur.

(iii) A long tail, strong claws, white large paws.

(iv) White body, paws for swimming, gills for respiration.


(iv) A white fur, fat below skin, keen sense of smell.

Question 12

Which option best describes a tropical region?

(i) hot and humid

(ii) moderate temperature, heavy rainfall (iii) cold and humid (iv) hot and dry


(i) Hot and humid
