Question

The rays of the sun do not fall equally all over the._____

Answer 1

Answer:

On 21st March and September 23rd, direct rays of the sun fall on the equator. At this position, neither of the poles is tilted towards the sun; so, the whole earth experiences equal days and equal nights. This is called an equinox.

Answer 2

Answer:

Due to the rounded nature of the planet, sun beams do not fall perpendicularly at every location.

Explanation:

Only half of the Earth's surface can be illuminated by the Sun's beams at once. Only twice a year, on September 23 and March 21, do the rays of the sun reach the North and South Poles equally. The Sun's vertical rays fall directly on the Equator on these two days. The Sun's rays steadily advance toward the South Pole and move away from the North Pole from September 23 to December 21. On December 21, the rays are 23 1/2 degrees beyond the South Pole and are 23 1/2 degrees short of the North Pole. Right now, the Arctic Circle, which surrounds the North Pole, and the Antarctic Circle, which is located around the South Pole, both receive sunshine Pole, is without sunlight.
