If the Moon in its orbit around Earth moves between Earth and the Sun and then 2 weeks later it moves to the other side of Earth as seen from the Sun, why then do we not see both a solar and a lunar eclipse every month?
A)The Moon's orbital plane is at right angles to the ecliptic.
B)Earth's orbital plane is slightly inclined to the ecliptic.
C)The Moon's orbital plane is slightly inclined to the ecliptic.
D)The Moon's orbital plane is inclined slightly to the celestial equator.

The reason we do not see both a solar and a lunar eclipse every month is because the Moon's orbital plane is slightly inclined to the ecliptic (the path of the Sun in the sky). As a result, most of the time the Moon appears to pass above or below the Sun from our perspective on Earth, and most full or new moons do not result in an eclipse. Only when the Moon's orbit intersects with the ecliptic at the right angle can we see a solar or lunar eclipse.
