| For a horizontally moving object, what is the latitude where it is effected most by Earth's rotation? | The poles. |
| What area of Earth is not effected by the Coriolis effect? | The Equator |
| (T or F) Toilets in Australia flush in the opposite direction than they do here because of the Coriolis Effect. | F |
| Parallelism of the Axis (def) | Earth's axis is tilted 23.5 degrees toward Polaris for all points in its orbit around the sun |
| Axis (def) | Imaginary line around which Earth spins |
| 2 pieces of evidence for Earth's Rotations | Foucault Pendulum & Coriolis Effect |
| 3 Results of Earth's rotation | Length of day, Direction of Sunrise, Coriolis Effect |
| Where does the Earth spin the fastest? | At the equator |
| Foucault Pendulum (def) | Each hour the pendulum shifts approx. 11 degrees in a clockwise direction knocking over all the pins that surround it. The shift is caused by Earth's rotation. If the Earth did not rotate only 2 pins (in a straight line from each other) will be knocked down. |
| Revolution (def) | The Earth's counterclockwise orbit around the sun; Earth is a satellite of the sun. |
| Ellipse (def) | Elongated closed curve; similar to a stretched out oval |
| Date of perihelion | Jan 3rd or 4th |
| Date of aphelion | July 4th |
| Perihelion (def) | Point in the Earth's orbit when it is closest to the sun |
| Aphelion (def) | Point in the Earth's orbit when it is furthest from the sun |
| Degrees of the tilt of the Earth | 23.5 degrees |
| Why are summers hotter than winters? | The Earth's tilt causes sun light to hit some areas more directly than others, concentrating the heat energy, thus causing summer. |
| 2 pieces of evidence for Earth's Revolution | Parallax Effect & Seasonal changes in constellations |
| Parallax Effect (def) | The apparent shift in a star's position that occurs because Earth has moved in its orbit |
| 4 Constellations that aren't seen in the summer | Orion, Taurus, Gemini, Canis Major |
| Constellation that isn't seen in the winter | Scorpio |
| 3 Reasons for Seasons | Revolution of Earth around the sun, Tilt of Earth on its axis, Parallelism of Earth's axis |
| Date of Spring Equinox | On or about March 20th or 21st |
| Date of Fall Equinox | On or about Sept. 22nd or 23rd |
| Equinox (def) | Time of the year when neither hemisphere is tilted toward the sun, the sun is at zenith at noon on the equator, Daylight and nighttime hours are equal |
| Only 2 dates when the sun rises due east and sets due west. | The Equinoxes (March 20th/21st & Sept. 22nd/23rd |
| Solstice (def) | The point at which the sun reaches its greatest distance North or South of the Equator |
| Date of Summer Solstice | On or about June 21st |
| Date of Winter Solstice | On or about December 21st |
| Latitude where the sun is at zenith on Dec. 21st | Tropic of Capricorn 23.5 degrees south |
| Latitude where the sun is at zenith on June 21st | Tropic of Cancer 23.5 degrees north |
| Solar Noon | Time of the day when the sun has reached its highest point in its path through the sky, for that latitude |
| Solar Time | Time told by the sun (may vary slightly with in a time zone) |
| Daylight Savings | When clock time is advanced one hour (April-Oct) |
| If it is 7pm in NYC long. 75 degrees W. What time is it in LA long 120 degrees W | 4pm |
