| In what direction does earth spin on its axis? | The earth spins on its axis west to east. |
| What is the equator? | The Equator usually refers to an imaginary line on the Earth's surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. |
| What is a day? | The time it takes for the earth to spin once on its axis (24 hours). |
| What is revolution? | One complete orbit around the sun. |
| What is a year? | The time taken by the earth to make one revolution around the sun. (365 days) |
| What is a season? | The passing of a year can bring a marked change in the weather and the surrounding environment. This is caused by the tilt of the earths axis. |
| What are the 4 seasons | |

| Why are the north and south poles the coldest parts of the earth? | Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn’t come up at all for months at a time. So the days are just like the nights—cold and dark. |
| Why are the regions on the equator hotter? | The equator is hotter than other areas of the earth, such as the poles, because it receives more direct sunlight than other areas. It is a common misconception that the equator is hotter due to it being closer to the sun than other areas of the earth. |
| What is an equinox? | When the duration of the day is equal to that of night. |
| What is a sundial? | A sundial is a clock that uses the position of the Sun to indicate the time. |
| How does a sundial work? | A sundial works by casting a shadow that is determined by the sun's position the sky. |
| what is solstice? | pecific |
| What is a celestial equator? | The projection into space of the earth's equator. |
| Since now we know what an equinox and solstice is here is a diagram of when it happenes during earths revolution. |
