Question

Why does a solar eclipse happen?

Answer 1

A solar eclipse occurs when the Earth, moon, and sun align together, and the moon in between casts a shadow over the Earth.

Answer 2

Sometimes when the Moon orbits Earth, the Moon moves between the Sun and Earth. When this happens, the Moon blocks the light of the Sun from reaching Earth. This causes an eclipse of the Sun, or a solar eclipse. During a solar eclipse, the Moon casts a shadow onto Earth.
