| Question | Answer |
|---|---|
| An orbit and revolution both equal a_______ | Year |
| What is the tilt of Earth's axis | 23.5 Degrees |
| What is the definition of a season | Characterized by a pattern of tempatures |
| Why does the change of the amount of rays that hit earth matter what does each direct and indirect rays cause. | Because when the rays are direct it is warmer.And when the rays are indirect it is colder because the light isn't as strong. |
| In comparing winter and summer when is the sun lower | In the winter because there is less sunlight so the sun is lower because then the sun moves faster. |
| In comparing the temperatures at Earths equator to the poles is there more or less variation in temperature. | More variation because the poles get lots of indirect sunlight so its cold but the equator get direct sunlight so it is warm. |
| What 2 things impact the length of a season. | Earths tilt Where earth is in it's orbit. |
| What contributes to the seasons besides earth's tilt. | Position in orbit. |
| What force keeps all objects in orbit? | Gravity |
| Why can we see the moon. (2 reasons) | The moons orbits around earth It reflect sunlight |
| What is a lunar eclipse and what order are the moon, sun, and, earth. | A lunar eclipse is when earths shadow goes over the moon.The order of the 3 objects is first sun then earth then moon. |

| How are the sun, moon, and earth aligned during a neap tide | sun, moon, earth, in a 180 degree angle.Happens every 14 days. |
| Between the sun and the moon who's gravitational pull is the strongest. | The moon |
| What are tides and why is their timing predicable. | Because we know they happen 50 minutes later every day. |
