Class 7 Geography Chapter 5 Winds Textbook Questions and Answers
1. Rewrite the following statements after choosing the correct option:
2. Identify the type of winds from the description given below:
3. Given below are the values of air pressure in millibars. Using the same, draw diagrams to show a cyclone and an anticyclone:


4. State one reason why:
(ii) During summers, land heats up quickly as compared to water & an area of low pressure is created on the land whereas an area of high pressure is created on the water.
(iii) But during winters low pressure is created on the water and an area of high pressure is created on land as it cools down quickly as compared to the water.
(iv) As winds blow from high pressure areas to low pressure areas, it blows from sea to land in summers & from land to sea in winters.
Thus the monsoon winds in summer come from sea but the retreating monsoon winds come from land.
5. Complete the flow chart:
Answer:

6. Answer in short:
(ii) But due to the rotation of the earth in the northern hemisphere the winds deflected towards the right of their original direction whereas in the southern hemisphere they get deflected towards the left of their original direction which causes the cyclone winds to blow in a circular manner.
Activity:

Formative Assessment
Can you tell?
Observe the diagrams given below. Answer the questions related to sea and land breeze
Question 1.
Why do the breezes blow from the sea to the land during the day?
Answer:
During the day as land gets heated up faster than water, an area of low pressure is created on land whereas there is a region of comparatively higher pressure on the sea. As a result the breezes blow from the sea to the land during the day.

Solution & Step-by-Step Answer:
We mostly use the technique/object which will blow air with maximum force to move the rolls to the other end of the table with a greater speed.
Question 5
Maharashtra Board Solution
Can a bottle filled with water be moved to the other end of the table in this manner? Can we use the same method that you tried for moving paper rolls?
Solution & Step-by-Step Answer:
A bottle filled with water cannot be moved to the other end of the table in this manner. We cannot use the same methods that we tried for moving paper rolls to move a bottle filled with water as it is heavier in weight, (we can if we tilt the table which was an option.)

Question 3
Maharashtra Board Solution
The Indian subcontinent experiences monsoon and retreating monsoon seasons.
Solution & Step-by-Step Answer:
(a) Monsoon winds are generated due to uneven heating of land & water in different seasons. During summers, monsoon winds blow from sea to land & in winter they blow from land to the sea.
(b) The influence of monsoon winds is seen in summer season in the Indian subcontinent due to high temperature & low pressure in Thar desert region & Punjab plains. (c) As these winds blow from sea to land the Indian subcontinent experiences monsoon (rainy) season. (d) During winters, due to high pressure & low temperature in the Indian subcontinent & comparatively low pressure & high temperature in the Indian ocean winds blow from land to sea. (e) This is the retreating monsoon season in the Indian subcontinent. Answer the following in detail:

(i) Cyclones occurring in the western part of the Pacific ocean along the coasts of Japan, China, Philippines, etc. are known as ‘Typhoons’. (ii) These storms arise in the months between June & October. (iii) Due to high velocity winds & heavy rains, these prove to be destructive. (iv) The cyclones in the Caribbean Sea are known as ‘hurricanes’. These are also destructive in nature. (v) During these storms, the minimum velocity of the wind is 60 km per hour. (vi) Cyclones also originate in the temperate zone but they are not so powerful & hence are not destructive.
Question 3
Maharashtra Board Solution
What are anticyclones?
Solution & Step-by-Step Answer:
(i) Under specific atmospheric conditions, the air pressure in a particular region increases & the pressure in the surrounding areas remain low.
(ii) In this situation, winds blow from the centre towards the surrounding areas in a circular manner. (iii) In the northern hemisphere, these winds blow in a clockwise direction whereas in the southern hemisphere they blow in an anticlockwise direction. (iv) During anticyclone, the skies are clear, winds blow with lesser velocities and the weather is pleasant. Can you tell? Observe the picture given below and answer the following questions.:
Question 2
Maharashtra Board Solution
What is the direction of the Westerlies in the southern hemisphere?
Solution & Step-by-Step Answer:
Westerlies blow from north west to south east in the southern hemisphere
Question 3
Maharashtra Board Solution
Which planetary winds blow from the mid-latitudinal high pressure belts to the subpolar low pressure belts in the northern hemisphere?
Solution & Step-by-Step Answer:
The Westerlies blow from mid latitudinal high pressure belts to subpolar low pressure belts in the northern hemisphere
Question 4
Maharashtra Board Solution
Why is the direction of polar winds not the same in both the hemispheres?
Solution & Step-by-Step Answer:
The rotation of the earth causes the change in the direction of winds in both the hemisphere. So polar winds blow from northeast to south west in the northern hemisphere & from south east to north-west in the southern hemisphere.
Question 5
Maharashtra Board Solution
Name the winds that blow in the southern hemisphere.
Solution & Step-by-Step Answer:
Easterlies, Westerlies and Polar Winds blow in the southern hemisphere.
Question 6
Maharashtra Board Solution
