| 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 is a moon phase? | The different appearances of the moon due to its changing position. |
| 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 |
| 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 |
| During what phases of the moon doe eclipses occur? | New and full moon phases |
| 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 are the period of rotation and revolution for the moon? | 28 days |
| rotation | The spinning motion of a planet about its axis. |
| revolution | The movement of an object around another object. |
| orbit | The path of an object as it revolves around another object in space. |
| phase | One of the different shapes of the moon as seen from Earth. |
| eclipse | The partial or total blocking of one object by another. |
| solar eclipse | The blocking of sunlight to Earth that occurs when the moon is between the sun and Earth. |
| umbra | The darkest part of a shadow. |
| penumbra | The part of a shadow surrounding the darkest part. |
| lunar eclipse | The blocking of sunlight to the moon that occurs when Earth is directly between the sun and moon. |
| tide | The daily rise and fall of Earth's waters on shores. |
| gravity | The attractive force between two objects; its magnitude depends on their masses and the distance between them. |
