| Question | Answer |
|---|---|
| The sky moves from | East to west |
| The Earth moves from | West to east |
| The point directly overhead on the local sky is called | Zenith |
| The cardinal directions (North, South, East and West) on the local sky, lie along the: | Horizon |
| The cardinal directions (North, South, East and West) on the local sky, are measured in degrees: | Azimuth (N 0, E 90, S 180, W 270) |
| This is the line that runs from North to South on the Local Sky: | Meridian (line that divides sky into east and west) |
| The path that the Sun takes: | Ecliptic |
| On the Celestial Sphere this is equivalent to longitude: | Right ascension |
| On the Celestial Sphere this is equivalent to latitude: | Declination |
| On the Celestial Sphere this is lies above Earth's Equator: | Celestial Equator |
| In the Local Sky, the number of degrees a star is above the horizon | Altitude |
| You are looking toward the north and see the Big Dipper to the right of Polaris. Fifteen minutes later (a very short period of time), the Big Dipper will appear to have moved, slightly and roughly, in what direction? | up(away from the horizon) |
| You are looking toward the north and see the Big Dipper to the right of Polaris. Six hours later, the Big Dipper will appear to have moved in roughly what direction? | Counterclock wise |
| How much time is there between when a star rises and when it sets in East? | 12 hours |
| How much time is there between when a star rises and when it sets in South of East? | 6 hours |
| How much time is there between when a star rises and when it sets in North? | At north pole all the stars are visible 24 hours |
| In the celestial sphere model, the Sun’s position is constantly changing; the path that it follows is called the ecliptic. About how long does it take the Sun to complete one trip around the ecliptic? | 365 days (because that is how long the Earth takes to fully rotate around the sun) |
| What do we call the day when the Earth spins exactly 360 degrees? | Sidereal (360) Day |
| What do we call the day when the Earth spins exactly 361 degrees? | Solar day, The Earth rotates as well so for it be in the same position |
| How are those 361 degrees measured? | To see when sun is high in the sky today to when the sun is high in the sky tomorrow |
| Where do zodiac constellation lie on? | On the ecliptic |
| the sun is in a different zodiac every_______? | month (30 days) |
| When is the Equinox? | When the day and night are equal everywhere on the Earth. |
| A certain region on Earth’s surface always has the highest temperatures in June and the lowest temperatures in December. Which of these statements explains why the temperatures are LOWEST in December? | This region is tilted the farthest away from the sun in December. |
| What two factors impact the length of a season? | Earth’s tilt relative to the sun (direct light - higher temperature and indirect light - lower temperature) and Earth’s position in its orbit around the sun |
| Rotational speed of earth affects _________ | daily temperatures |
| The distance of the earth from the sun affects the _______ | temperatures |
| In the Northern Hemisphere, between what dates does the location of the Sun's rising and setting shift a little farther north each day? | From 12/22 a little further north until 3/21 (vernal equinox) until it is exactly east |
| When does the sun rise due east? | On equinoxes |
| Earth’s axis slowly but continuously points in different directions, a movement known as ____. | Precession |
| How long is a sidereal day? | 23 hours 56 mins |
| How long does it take Earth to spin 1 degree? | 4 mins |
| Inverse square | 1/x^2 so if x=2, ¼ |
