Why do you not see a solar eclipse every month?

Answer 1

We would if the moon's orbit exactly overlapped the ecliptic, but it does not. Most of the time at the time of full moon the moon is above or below the ecliptic, the path traced out by the orbit of the sun.

Answer 2

Solar eclipses occur when the moon comes between the Earth and the Sun, but the moon's orbit is inclined by about 5 degrees to the Earth-sun plane. As a result, the moon's shadow usually misses the Earth during a new moon (when solar eclipses occur), hence they don't happen every month.

Answer 3

Because of the way the Moon revolves and The positions of he moon, sun, and earth.
