Worksheet Title: *Our Solar System: Earth’s Rotation*

#### Explanation of the Concept:
The Earth spins on its axis once every day. This spinning motion is called rotation. As the Earth rotates, different parts of it face the Sun at different times:
- When a part of Earth faces the Sun → daytime
- When that same part turns away from the Sun → nighttime

This rotation causes the cycle of day and night.

Question 1: What do we call the movement of Earth on its axis?

Options:
- ☐ Rotation
- ☐ Revolution

✔ Correct Answer: Rotation

Explanation:
- Rotation is when an object spins around its own axis (like Earth spinning on its axis).
- Revolution is when an object orbits around another (like Earth going around the Sun).

So, the movement of Earth on its axis is called rotation.

Question 2: What happens when the Earth rotates on its axis?

Options:
- ☐ Day and night
- ☐ Winter, spring, summer and fall

✔ Correct Answer: Day and night

Explanation:
- The rotation of Earth causes day and night because one side faces the Sun (day) while the other side is in darkness (night).
- The seasons (winter, spring, summer, fall) are caused by Earth’s tilt and its revolution around the Sun, not by rotation.

Question 3: How long does one rotation on Earth’s axis take?

Options:
- ☐ 24 hours, or 1 day
- ☐ 12 months

✔ Correct Answer: 24 hours, or 1 day

Explanation:
- One full rotation of Earth on its axis takes about 24 hours, which we call one day.
- 12 months is the time it takes for Earth to complete one full revolution around the Sun (a year), not a rotation.

✔ Final Answers:

1. Rotation
2. Day and night
3. 24 hours, or 1 day

These answers are based on the scientific understanding of Earth’s rotation and how it affects our daily life.

💡 Fun Fact: Even though Earth rotates once every 24 hours, the actual time it takes for Earth to rotate once relative to the stars is about 23 hours and 56 minutes — this is called a sidereal day. But for everyday use, we use the 24-hour solar day.
