Maharashtra State PSC Model Paper 5

The correct answer is 1 and 3 only.

• The length of day and night varies throughout the year because the equator is tilted 23.5 degrees from the Earth's orbit. 
• The Earth revolves around the Sun. It is tilted vertically at an angle of 23.5° on its circumambulation route, half of the year when it is summer the northern part is inclined towards the sun.
• The second half of the time when it is cold, the Earth is away from the Sun.
• Changes in the tilt of the earth can affect the intensity of the weather more tilt means more heat and less cold; Less tilt means less heat and more cold.

Important Point

• The axle of the earth is not perpendicular to its orbit. Hence statement 1 is correct.
• The length of day and night varies throughout the year because the equator is tilted 66.5 degrees from the Earth's orbit. Hence statement 2 is incorrect.
• If the earth was not inclined, we would not have experienced the weather. Changes in the tilt of the earth can affect the intensity of the weather. Hence statement 3 is correct.
