Filled-in Worksheet:

#### ROTATION
- The Earth’s movement through space affects life on Earth.
- We experience day and night because of this movement on the Earth’s axis known as rotation.
- It takes the Earth 24 hours to rotate one time in which we experience day and night.
- The Earth’s axis is an invisible line that intersects the Earth through both the North and South poles.

#### REVOLUTION
- The Earth moves along a path around the Sun. This path is known as an orbit.
- One complete trip on this path around the sun is known as a revolution.
- It takes the Earth 365 1/4 days to complete its journey around the Sun.
- Every 4 years, we take the extra 1/4 days from the previous years, combine them and add an extra day to the calendar called leap year.

Explanation:

1. Rotation:
- The Earth rotates on its axis, completing one full rotation in approximately 24 hours. This rotation causes the alternation between day and night.
- The axis of rotation is an imaginary line passing through the North and South poles.

2. Revolution:
- The Earth revolves around the Sun in an elliptical orbit, completing one full revolution in approximately 365.25 days (365 days and 1/4 day).
- To account for the extra 1/4 day each year, every 4 years an extra day is added to the calendar, creating a leap year.

This completes the worksheet by filling in all the blanks with the appropriate terms from the vocabulary list.
