we mean the time when the Sun passes the celestial meridian, reaching its maximum height in the sky. As the Earth turns on its rotation axis, it also moves along its orbit around the Sun. ... The speed chosen is the average speed of the Sun's ecliptic motion, leading to a mean solar day of 24 hours.

Important Questions Test: Motions Of The Earth - Question 8

Which of the following is NOT the season

Detailed Solution for Important Questions Test: Motions Of The Earth - Question 8

Winter, Autumn and Spring are names of seasons whereas, Axis is an imaginary line which runs through the poles on which the Earth rotates. 

Important Questions Test: Motions Of The Earth - Question 9

Two motions of the earth are

Detailed Solution for Important Questions Test: Motions Of The Earth - Question 9

Rotation and Revolution are two motions of the earth. When earth spins or rotates around its axis, that movement of spinning is called Rotation of Earth. And when earth spins or revolves around the sun, that movement is called Revolution of Earth.

Important Questions Test: Motions Of The Earth - Question 10

Which of the following is responsible for the change of seasons
I. Revolution of the earth
II. Inclination of the axis of the earth
III. Rotation of the earth 
IV. Revolution of moon
Options are as follows:

Detailed Solution for Important Questions Test: Motions Of The Earth - Question 10

The rotation of the earth on its own axis and the revolution of earth around the sun cause changes in season and day and night. The change in seasons is caused by the rotational tilt of the earth on its axis when it revolves around the sun.

The earth has an axial tilt of 23.5 degrees which means that its rotation axis is inclined to its orbital axis at an angle of 23.5 degrees. This causes one pole of the earth to be directed more towards the Sun on one side of the orbit, and the other pole on the other side. This is the reason for occurrence of 'seasons' on earth'.

 

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.

Important Questions Test: Motions Of The Earth - Question 16

Poles experience about

Detailed Solution for Important Questions Test: Motions Of The Earth - Question 16
