Final answer:
The moon, as it enters the penumbra, experiences partial shadowing.
Step-by-step explanation:
The moon, as it enters the penumbra, experiences partial shadowing. The penumbra is the lighter, more diffuse region of darkness in the shadow of Earth or the Moon. It is not a total shadowing of the moon nor is it shadowing of the sun.
Only when the moon enters the umbra, the darkest region of the shadow, does it experience total shadowing.
