Key Points
- The Earth rotates around its axis in a counterclockwise direction when viewed from above the North Pole, which corresponds to a rotation from West to East.
- This rotation is the reason why the Sun, Moon, and stars appear to rise in the East and set in the West.
- The Earth's rotation period is approximately 24 hours, which defines the length of a day.
- The rotation from West to East is responsible for the phenomenon of the Coriolis effect, which impacts weather patterns and ocean currents.
Additional Information
- Earth's Axis: The axis of rotation is an imaginary line passing through the North and South Poles, tilted at an angle of 23.5 degrees relative to its orbital plane.
- Day and Night Cycle: The rotation of Earth causes one hemisphere to face the Sun (day) while the other faces away (night).
- Coriolis Effect: This phenomenon, caused by Earth's rotation, deflects moving objects like winds and ocean currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
- Geostationary Satellites: These satellites orbit Earth from West to East at the same rotational speed, appearing stationary relative to a specific location on Earth's surface.
- Historical Understanding: The concept of Earth's rotation was first proposed by ancient astronomers like Aryabhata and later confirmed with modern scientific evidence.
