Question

2. Why does it become completely dark during total solar eclipse​

Answer 1

It is because the moon comes in front of the sun. So the sunlight does not reach Earth and it becomes dark.

Answer 2

Answer:

during a solar eclipse, the Moon moves between the Earth and the Sun. When this happens, part of the Sun's light is blocked. The sky slowly gets dark as the Moon moves in front of the Sun. When the Moon and Sun are in a perfect line, it is called a total eclipse.
