Based on the educational material provided, here is the solution to the concepts presented in the worksheet regarding Earth's movement.
Step-by-Step Analysis
1. Analyzing Earth's Rotation
*
Definition: The text defines "rotate" as spinning or turning. It explains that there is an imaginary line through the center of the Earth called the
axis.
*
Key Fact 1 (Time): The worksheet states that one full rotation takes
24 hours (or one day).
*
Key Fact 2 (Effect): This spinning motion is what causes
day and night. As the Earth spins, different parts face the sun (day) or face away from it (night).
*
Direction: The diagrams show the Earth spinning counter-clockwise when viewed from above the North Pole.
2. Analyzing Earth's Revolution
*
Definition: The text defines "revolve" as going around something else. Specifically, Earth revolves around the
Sun.
*
Key Fact 1 (Path): The path Earth takes around the Sun is called its
orbit.
*
Key Fact 2 (Time): The worksheet states that one full revolution takes
365 $\frac{1}{4}$ days (approximately one year).
*
Key Fact 3 (Effect): While not explicitly detailed in the short bullet points, this movement combined with the tilt of the axis is responsible for the changing
seasons and the length of a year.
3. Comparing the Two Movements
*
Rotation = Spinning on an axis $\rightarrow$ Creates Days (24 hours).
*
Revolution = Orbiting the Sun $\rightarrow$ Creates Years (365.25 days).
4. Verification
* Does the Earth spin on its axis? Yes.
* Does this take 24 hours? Yes.
* Does the Earth orbit the Sun? Yes.
* Does this take ~365 days? Yes.
* The distinction is clearly made between the daily cycle (rotation) and the yearly cycle (revolution).

Final Answer:
Earth's Rotation vs. Earth's Revolution Summary:
*
Rotation:
*
Action: Earth spins on its imaginary axis.
*
Time: Takes
24 hours (1 day).
*
Result: Causes
day and night.
*
Revolution:
*
Action: Earth travels in an orbit around the Sun.
*
Time: Takes
365 $\frac{1}{4}$ days (1 year).
*
Result: Defines the length of a
year (and contributes to seasons).
Parent Tip: Review the logic above to help your child master the concept of rotation vs revolution worksheet.
