| Question | Answer |
|---|---|
| What is astronomy? | The study of the moon, stars and other objects in space is called astronomy. |
| What’s Earth’s axis? | Earth’s rotation on its axis causes day and night. |
| What is rotation? | Earth’s spinning on its axis is called its rotation. |
| What causes day and night? | Earth’s rotation on its axis causes day and night. |
| How long does it take Earth take make one complete rotation? | 24 hours. |
| Day + Night = 1 Day Explain what the formula means. | One rotation is 24 hours day and night equal to a full rotation. |
| What is revolution? | The movement of one object around another object is called revolution. |
| How is revolution different from rotation? Explain. | Rotation is different from Revolution because rotation is earth spinning on its axis and revolution is the movement of one object around another object. |
| How long does it take Earth to make one complete revolution? | It takes one year to make a revolution around the sun. |
| What is Earth’s orbit? | Earth's path as it revolves around the sun. |
| How long would one day be if Earth only revolved (revolution) around the sun and didn’t rotate (rotation)? | One day would be 365 ¼ days. |
| Exactly, how many days equals a year? (must have a fraction in it) | 365 ¼ days in a year |
| What is a leap year? | Four years of about 365 ¼ days each can be approximated by taking 3 years of 365 days and a fourth year of 366 days. We know this fourth year as a leap year. |
| Why is it warmest near the equator and not the poles? | Closer to the poles, sunlight hits Earth’s surface at an angle. Near the poles, energy from the sun is spread out over a greater area. That is why it is warmer near the equator than near the poles. |
| Earth’s axis is tilted how many degrees? | Earth’s axis is tilted 23.5 degrees from the vertical. |
| What does the tilt create for our planet? | The tilt creates seasons for our planet`1 |
| If Earth wasn’t tilted, then describe what the seasons would be like on Earth. | It would be one season forever because if Earth’s axis were straight up and down relative to the sun, temperatures would remain fairly constant year-round |
| What is latitude? | Latitude is a measurement of distance from the equator, expressed in degrees north or south. |
| What is Queensbury’s latitude? Hint: research it and remember your units too. | 43.3536° N, 73.6772° W |
| What is a solstice? | The two days of the year on which the noon sun is directly overhead at either 23.5 South or 23.5 North. |
| When does it occur? | The solstice occurs two days each year. |
| Which date is the longer day, with more sunlight in the northern hemisphere? | June 21. |
| What is an equinox? | The noon sun is directly overhead at the equator. Each of these days is known as an equinox. |
| What is the vernal equinox, and when does it occur? | The vernal equinox is the day of the year that marks the beginning of spring in the Northern Hemisphere. The vernal equinox occurs around March 21. |
| What is the autumnal equinox, and when does it occur? | An autumnal equinox is the day of the year that marks the beginning of fall in the Northern Hemisphere. The autumnal equinox occurs around September 23. |
