| Why does the moon look different at different times of the month? | Because the moon changes positions with respect to the earth and teh soon. As the moon revloves around the earth, the amount of sunlight on the side of the moon that faces the earth changes. |

| What are the phases of the moon. Look at chart. | first quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning crescent, new moon, waxing crescent |
| When the moon is waxing is the sunlit part getting larger or smaller? | larger |
| When the moon is waning , is the sunlit fraction getting larger or smaller? | smaller |
| why do we only see one side of the moon | because the period of rotation is the same as its period of revolution |
| If you lived on the far side of the moon whould you ever have sunlight? Would you ever see the earth? | You would have sunlight but you would never see the earth. |
| What is an eclipse? | An eclipse occurs when the shadow of one celestial body falls on another |
| What is an lunar eclipse? | when the earth comes between the sun and the moon and the shadow of the earth falls on the moon |
| What is a solar eclipse? | when the moon comes between the earth and the sun and the shadow of the moon falls on part of the earth |
| What does a solar eclipse look like? | The moon covers the sun but you can see the sun peeking out from the edges (corona) |
| Why can't you see a solar eclipse from anywhere on earth? | Because the shadow of the moon on the earth is small, so a solar eclipse can be viewed from only a few locations |
| what is an annular eclipse? | when a small ring of sunlight shows around the outer edge of the moon. When the moon is farther away from the earth |
| During what phases of the moon doe eclipses occur? | New and full moon phases |
| How does the moon look during a lunar eclipse? | Red |

| why isn't there an eclipse every month? | Because the moon's orbit is tilted so the moon is out of the earth's shadow for most full moons and the earth is out of the moon's shadow for most new moons. |
| What is closer to the earth -- the moon or the sun | the moon (384,000 km). The sun is 150 million km (or one AU) |
| How are lunar eclipses different from solar eclipses? | A lunar eclipse: the earth comes between the sun and the moon, the light around the moon is red. Solar eclipse: moon comes between the earht and the sun and the shadow of the moon falls on part of earth. the moon covers the sun and the shadow covers part of the earth |
| What is a highland on the moon? | mountains |
| What is a rilles? | valley |
| What are the period of rotation and revolution for the moon? | 27 days, 8 hours |
| what is the diameter of the moon ( approximately) | 3476 km |
| What is the denisty of the moon | 3.334 g/cm3 |
| what is the surface temperature of the moon? | -170 t0 134 degrees C (celsius) |
| what is the surface gravity? | 17% of earth's |
