Answer

**Step-by-Step Solution:**

1. **Understanding the Movement of Stars**:
- Stars appear to move across the night sky. They seem to rise in the east, move across the sky, and then set in the west.

2. **Identifying the Cause of This Movement**:
- The apparent movement of stars is not due to the stars themselves moving around the Earth, but rather due to the motion of the Earth.

3. **Earth's Rotation**:
- The Earth rotates on its axis from west to east. This rotation is what causes the stars to appear to rise in the east and set in the west.

4. **Conclusion**:
- Therefore, the reason stars rise and set in the night sky is due to the Earth's rotation.

5. **Final Answer**:
- The correct answer to the question is that stars rise and set in the night sky because of the Earth's rotation.
