Earth Axis | MCQs

Explanation

• The Earth is tilted at an angle of 23.5 degrees.
• This tilt is responsible for the changing of the seasons and the difference in the amount of sunlight reaching a given point on the surface during the course of a year.
• The tilt varies between 22.1 and 24.5 degrees in a cycle that averages about 40,000 years.

Explanation

At this position, neither of the poles is tilted towards the sun i.e shines vertically overhead at noon on the Equator.

Explanation

• The Earth's axis is an imaginary line that runs through the North Pole and the South Pole, around which the Earth rotates.
• It is an imaginary reference point, not a physical object or shape.

Explanation

In the Northern Hemisphere, the March equinox is called the vernal or spring equinox 

On the Gregorian calendar, the northward equinox can occur as early as 19 March or as late as 21 March at 0° longitude.

while 

 the September equinox is called the autumnal or fall equinox on 23 September
