Why don't we see solar and lunar eclipse every lunar cycle?

Answer 1

We do not see those because the sun and the moon are in a line.

Answer 2

We don't see solar and lunar eclipses every lunar cycle because the orbits of the Earth, Moon, and Sun are not perfectly aligned. Solar eclipses occur when the Moon passes in front of the Sun, blocking its light from reaching Earth, and this alignment is not always present. Similarly, lunar eclipses occur when the Earth casts a shadow on the Moon, and this alignment also does not happen every month due to the tilt of the Moon's orbit.
