| Question | Answer |
|---|---|
| One complete revolution of Earth around the sun takes about: | one year |
| Earth has seasons because: | Earth's axis is tilted as it moves around the sun. |
| When the north end of Earth's axis is tilted toward the sun, North America will experience: | More direct rys and longer days |
| The phase of the moon you see depends on: | How much of the sunlit side of the moon faces earth |
| One complete revolution of Earth around the sun takes about: | one year |
| Earth has seasons because: | Earth's axis is tilted as it moves around the sun. |
| When the north end of Earth's axis is tilted toward the sun, North America will experience: | More direct rys and longer days |
| The phase of the moon you see depends on: | How much of the sunlit side of the moon faces earth |
| From new moon phase to full moon phase you see; | an increasing amount of the lighted side of the moon. |
| For a solar eclipse to occur: | when the moon is directly between the sun and the earth |
| Day and Night are caused by: | Eath's Rotation on it's axis |
| during what phase can a lunar eclipse occur? | full moon |
| when are tides highest? | when the sun, earth, and moon are nearly in line. |
| Tides are caused mainly by: | differences in how much the moon pulls on different parts of Earth. |
| Geosynchronus satellites above the equator: | stay above the same point on eaeth |
| How large is the moon compared to earth? | about 1/4 |
| scientists think the moon was formed when | a large object struck earth, and material from both bodies combined. |
| Inthe southern hemispher, the summer solstice occurs when the sun is directly overhead at | 23.5 south latitude |
| An equinox occurs when | neither end of Earth's axis is tilted toward or away from the sun |
| neap tides occur when | the sun's pull is at right angles to the moons |
| There are two low and high tides on earth every day because: | The moons gravitational pull on earth. |
| summer solstice: | June 21st |
| winter solstice: | december 21st |
| autumnal equinox | september 21st |
| vernal equinox | march 21st |

| wavelengths that are a little bit shorter than visible light are | ultraviiolet |
| most of earths incoming ultraviolet radiation is absorbed by | ozone |
| most of thje energy that heats earths atmosphere is | infared radiation |
| the total energy of motion in the molecules of a substance is called | thermal energy |
| heat from a campfire reaches you by | radiation |
| convection takes place because | cold air is more dense than warm air |
| cool air masses tend to | be more dense and flow under warm air masses |
| local winds differ from global winds because they | are caused by unequal heating within a small area |
| land breezes occur because | land cools off faster than water |
| relative humidity can be measured with a | psychrometer |
| when an air mass rises up a mountain side | the temperature decreases and the relative humidity increases |
