What two factors combine to keep the moon and Earth in orbit?
The two factors that keep Earth and the moon in orbit is inertia and gravity.
Section 3-Phases, Eclipses, and Tides
What causes the phases of the moon?
The phases of the moon are caused by how much of the sunlit side of the moon faces Earth.
What are solar and lunar eclipses?
A solar eclipse occurs when the moon passes directly between Earth and the sun, blocking sunlight from Earth. A lunar eclipse is when Earth blocks sunlight from reaching the moon.
