Classify the following events as either a Solar Eclipse, Lunar Eclipse, or neither: 1) The Moon passes between the Earth and the Sun; 2) The Earth casts a shadow on the Moon; 3) A full moon occurs without any shadowing; 4) The Moon is in the Earth's shadow during a full moon.

The first event is a solar eclipse, because the Moon moves between Earth and Sun, blocking part or all of the Sun’s light. The second event is a lunar eclipse, as the Earth’s shadow falls on the Moon when it is on the opposite side of Earth. The third event is neither eclipse nor shadowing; a full moon simply means the Moon is opposite the Sun, but no shadow is involved. The fourth event is also a lunar eclipse, occurring when the Moon passes through Earth’s shadow during a full moon. For example, on October 14, 2023, the Moon entered Earth’s umbra, producing a total lunar eclipse visible from many parts of the world.
