CHAPTER 3 GEOGRAPHY

MOTION OF THE EARTH

EXTRA QUESTIONS

Q1. ANSWER THE FOLLOWING QUESTIONS:--

1.       Define rotation and revolution.

It takes 365days and 6 hours to complete revolution.

Due to this seasons are changed.  

2.       What is axis?

Ans: An imaginary line that makes an angle of 66^1/2 with its orbital plane.

3.       What would happen if the earth did not rotate?

Ans: If the earth did not rotate the following will happen:--

1.       On the earth day and will not be there.

2.       The portion of the earth facing the sun will experience continuous sunlight and heat.

3.       Other half will experience night and freezing cold.

5.       How does day and night occur?

Ans: Due to spherical shape of the earth, only half part of the earth receives sunlight from the sun at a time. This part experiences day and the other part that is in dark experience night.

6.       Difference between revolution and rotation?

Ans: The difference between revolution and rotation is as follows:--

SNO.	ROTATION	REVOLUTION
1.	Earth moves around its axis.	Earth moves round the sun.
2.	It takes 24 hours.(earth day)	It takes 3651/4days.

·         We must check pollution of water, land and air.

5.       Why some areas experience low pressure whereas some experience high pressure?

Ans: Some areas experience low pressure and some experience high pressure because of the following reasons:-

1.       Temperature decreases when we move up in the higher places.

2.       Air moves from high pressure to low pressure areas.

3.       Moving air is called wind, so some areas experience low pressure whereas some experience high.

6.       Why does atmosphere act as thin blanket of air?

Ans: It is because:-

·         The earth is surrounded by a thin layer of gases called atmosphere.
