| What would happen to Earth if we had no Sun? | We need the heat and light of the Sun, so it would be too cold and dark to live on Earth. |
| What causes the Earth to have night and day? | The rotation of the Earth |
| Why are there 365 and 1/4 days in one year? | Because it takes that long for the Earth to complete one revolution around the sun. |
| What does it mean to revolve? | To make a path around or orbit |
| What 2 motions is the Earth doing at the same time? | It rotates (spins) on its axis and revolves (makes a path) around the sun. |
| Why do we have seasons? | Because the Earth is tilted as it revolves around the sun. |
| How long does it take for the Earth to make one complete revolution around the Sun? | 365 and 1/4 days or a year |
| How many high tides and low tides are there in one day? | 2 high tides and 2 low tides |
| Why does the Sun seem to be moving across the sky? | The sun isn't moving across the sky, the Earth is rotating. |
| What would happen if the Earth rotated faster or slower? | The length of the day would get shorter if it rotated faster or longer if it rotated slower. |
| What is at the center of our Solar System? | The Sun |
| It takes 365 days to go around the sun. If Earth took 730 days, what would happen to the seasons? | The seasons would be longer. Instead of 3 months each, they would be 6! |
| What is the Quarter Moon sometimes called? | The Half Moon |
