```									Solar and Lunar Eclipses         NAME ___________________________________________ PD _____

Refer to your textbook, pages 765 - 767, for explanations of eclipses.

1. Using words, but not pictures, what is a solar eclipse?

2. Draw a picture of the position of Earth, moon, and sun during a solar eclipse. Include the two

3. Define the following terms relating to a solar eclipse:

Umbra:

Penumbra:

4. During a solar eclipse, do more people see a partial eclipse or a full eclipse? Explain your

5. During what phase of the moon can a lunar eclipse occur? Why can it occur only during this
phase?

6. Draw a picture of the position of Earth, moon, and sun during a lunar eclipse. Include the two

7. According to the textbook, the reason why we don’t see a lunar eclipse every time the moon
O
orbits Earth is because “the moon’s orbit is tilted 5 relative to the ecliptic.” Convince me with an
explanation and/or drawing that you know why we don’t have lunar eclipses every moon cycle.
