| each 24-hr cycle of day and light is | day |
| why is an extra day added to February every four years | we added the extra day to the shortest mouth instead of wasting a day |
| what causes day and night | the rotation of earth around the sun |
| why is it warmer near the equator than near the poles | equator, sunlight hits earth's surface more directly |
| is a measurement of distance from the equator expressed in degrees north or south | latitude |
| each of the days of the year when the sun is overhead at either 23.5 degrees south or 23.5 degrees north | solstice |
| each of the two days of the year when neither hemisphere is tilted toward or away from the sun | equinox |
| what causes the phases of the moon,eclipses, and tides. | the positions of the moon,earth and the sun cause the following |
| what side of the moon always faces earth | nearside |
| what shape is the moon orbit | oval |
| the different shapes of the moon you see from earth are | phases |
| how often dies the moon go through a whole set of phases | each time it revolve around earth, that it about once a month |
| what does the phases of the moon you see depend on | how much sunlit side of the moon faces earth |
| new looks like | you see nothing |
| first quarter looks like | half of the lighted side of the moon (right) |
| full moon looks like | you can see the whole moon |
| third quarter looks like | half of lighted side of the moon (left) |
| waning gibbous looks like | almost all of it is lighted except the little curve on the right is not light |
| waning crescent looks like | almost nothing is showing except the little curve on the left is light |
| waxing gibbous looks like | almost all of it is lighted except a little curve in the left side is not light |
| waxing crescent looks like | almost all of it is not lighted except a little curve on the right is not light |
| the moon phases in order | full moon, waxing gibbous, first quarter, waxing crescent, new moon ,waning crescent, third quarter, waning gibbous , |

| what is the arrangement of earth, moon,and sun during a lunar eclipse | earth is directly between the moon and the sun |
| the rise and fall of level of the ocean | tides |
| what force pulls the moon and earth toward each other | gravity |
| what does the force of gravity between two objects depend on | on the masses of the objects and the distance between |
| true or false, the sun has no influence on earth tides | false |
| what factors can make tides vary even in places that are close to each other | where they and how close there are to the moon |
| for every force or action there is an equal and opposite force or | reaction |
| how many stages do multistage rockets have | 6 |
