1. Because the sun takes a year to travel around the sky, it crosses the two nodes of the moon's orbit about 6 months apart, and that causes eclipse seasons when the sun is close enough to a node to be eclipsed and Earth's shadow is close enough to the other node to eclipse the moon. During a solar eclipse, the moon is in which of the following phases?
new
first quarter
full
third quarter
2. Which of the following is true during a total solar eclipse?
The moon crosses in front of the sun.
The moon is illuminated by light traveling through Earth's atmosphere.
Earth's umbral shadow sweeps over the moon.
all of these
3. If the sun is not quite close enough to the node when the moon sweeps past, you will probably see which of the following?
the sun's corona
a penumbral eclipse
a total solar eclipse
a partial solar eclipse
4. During a total solar eclipse, which of the following would you expect to see?
prominences

5. During a lunar eclipse, the moon is in which of the following phases?
new
first quarter
full
third quarter
6. A lunar eclipse can only occur if the sun is located at which of the following?
far from either node of the moon's orbit
at the same node with the moon
at the opposite node from the moon
within the penumbra of Earth's shadow
7. To produce a penumbral lunar eclipse, the moon's orbit must do which of the following?
carry it through the center of the umbra
carry it far enough north or south to miss Earth's shadow
carry it partially into the umbra
carry it into the penumbra but not into the umbra
8. Why can an eclipse only occur during two eclipse seasons each year?
The sun is crossing a node in the moon's orbit.
The moon is farthest north or south of the ecliptic.

The moon is full or new.
