#### Questions:

1. When the Earth moves around the sun in a complete orbit is known as ________. It takes the Earth ________ days.

- Explanation: The movement of the Earth around the Sun in a complete orbit is called a revolution. This process takes approximately 365 days, which is why we have a year with 365 days (except for leap years, which have 366 days).

- Answer:
- When the Earth moves around the sun in a complete orbit is known as revolution. It takes the Earth 365 days.

2. The Earth spins on its ________. This means that different parts of the Earth receive more direct rays from the ________ at different times of the year.

- Explanation: The Earth rotates on its axis, which is an imaginary line passing through the North Pole and South Pole. As the Earth rotates, different parts of the planet face the Sun at different times, causing variations in sunlight intensity and leading to seasons.

- Answer:
- The Earth spins on its axis. This means that different parts of the Earth receive more direct rays from the sun at different times of the year.

3. It takes the Earth ________ hours to rotate one time in which we experience day and night.

- Explanation: The Earth completes one full rotation on its axis in approximately 24 hours, which is why we have a 24-hour day-night cycle.

- Answer:
- It takes the Earth 24 hours to rotate one time in which we experience day and night.

4. The equator divides the Earth into Northern and Southern hemispheres. When the Northern hemisphere is facing towards the Sun, it is ________ in that hemisphere.

- Explanation: The equator divides the Earth into two equal halves: the Northern Hemisphere and the Southern Hemisphere. During certain times of the year, the Northern Hemisphere tilts toward the Sun, receiving more direct sunlight, which results in summer in that hemisphere.

- Answer:
- The equator divides the Earth into Northern and Southern hemispheres. When the Northern hemisphere is facing towards the Sun, it is summer in that hemisphere.
