Rotation vs. Revolution
Rotation:

• Example: When the Earth rotates, the side facing the Sun experiences day, while the opposite side has night.
Revolution:
• Definition: Revolution is the movement of the Earth around the Sun in an elliptical orbit.
• Effect: It causes seasons (summer, winter, spring, autumn).
• Time Taken: The Earth completes one full revolution in 365¼ days (1 year).
• Example: Different parts of the Earth receive varying amounts of sunlight throughout the year, leading to seasonal changes.
Key Differences Between Rotation and Revolution:
Feature Rotation Revolution What it does Earth spins on its axis Earth moves around the Sun Causes Day and night Seasons Time Taken 24 hours (1 day) 365¼ days (1 year) Axis or Orbit? Spins around its axis Moves in an elliptical orbit around the Sun II. Questioning and Hypothesis
