Revolution vs Rotation — Comparison Table
| Basis | Revolution | Rotation |
|---|---|---|
| Definition | Movement around the sun in orbit | Spinning on its own axis |
| Time taken | 365.25 days (1 year) | 24 hours (1 day) |
| Axis of movement | Around the sun | Around Earth's own axis |
| Causes | Causes seasons and solar year | Causes day and night |
| Speed | About 30 km/second | About 1700 km/hour at equator |
| Tilt | Orbital plane is elliptical | Axis is tilted 23.5 degrees |
| Path | Elliptical orbit around sun | Circular motion about axis |
Key Points
- Revolution determines the year length; rotation determines the day length
- Earth's axial tilt combined with revolution creates seasons
- Rotation causes the apparent motion of sun and stars in the sky
- Both motions are essential for life on Earth
