Rotation and Revolutinon Vocabulary
| Question | Answer |
|---|---|
| rotate, rotation | to spin on an axis of the spinning of Earth on its axis that causes day and night to occur |
| axis | the imaginary line through the Earth that extends from the north pole to the south pole and its the center of the Earth's rotation |
| tilt | the slant of Earth's axis, which is 23,5 degrees from vertical compared to Earth's orbital plane around the Sun. As a result, the North Pole always points toward the North Star. |
| Revolve, revolution | move in an elliptical path around a center |
| Orbital path | the gravitationally-curved path of an object around a point in space |
| seasons | the four natural divisions of the year based on changes in temperature due to the varied amounts of sunlight (both intensity and number of daylight hours recieved) caused by the tilt of Earth during revolution. |
| hemisphere | half of a sphere: the Earth and the celestial shpere can be divided into northern or southern and western husmispheres |
| direct/idirect | Direct: the shortest possible way without intermediates. Indirect: any way other that the shortest way, possibly involving intermediates. Temperatures are higher where the Sun's rays are direct and lower where the Sun's rays are indirect |
| summer | the hottest season where you have the most direct rays and the lowest density |
| winter | the coolest season where you have the most indirect rays and the highest density |
| equator | an imaginary line on the part of the Earth that has the most direct rays |
| sun | the star in our solar system that gives us light |
| southern hemisphere | the lower part off the equator |
| northern hemisphere | the higher part off the equator |
