Question

discuss because its orbit is tilted with respect to the earth-sun plane, the moon spends most of its time either above or below the plane. how many times would the moon cross through the earth-sun plane each time it orbits earth?

Explanation:

When the moon orbits Earth, it has to cross from above the Earth - sun plane to below (or vice versa). Since it starts on one side (either above or below), to complete an orbit, it must cross the plane once to go to the other side and then cross it again to come back to the original side relative to the Earth - sun plane.

Answer:

The moon would cross through the Earth - sun plane \(2\) times each time it orbits Earth.
