question: What type of eclipse happens when a full moon moves through earth's shadow?
distractor3: planetary
distractor1: cycle
distractor2: solar
correct_answer: lunar
support: Sometimes a full moon moves through Earth's shadow. This is a lunar eclipse ( Figure below ). During a total lunar eclipse, the Moon travels completely in Earth’s umbra. During a partial lunar eclipse, only a portion of the Moon enters Earth’s umbra. When the Moon passes through Earth’s penumbra, it is a penumbral eclipse. Since Earth’s shadow is large, a lunar eclipse lasts for hours. Anyone with a view of the Moon can see a lunar eclipse.
