The Earth rotates from West to East.
Explanation
The Earth exhibits two primary motions: rotation on its axis and revolution around the Sun. These movements, combined with the inclination of the Earth's axis, determine phenomena such as day and night, seasons, and the apparent motion of celestial bodies.Analysis of Options:
- The Earth rotates from East to West. is Incorrect: The Earth rotates on its axis from West to East. This direction of rotation causes the Sun, Moon, and stars to appear to rise in the East and set in the West.
- The Earth revolves in a circular orbit. is Incorrect: The Earth revolves around the Sun in an elliptical orbit, not a circular one. This elliptical path results in the Earth being closest to the Sun at Perihelion and farthest at Aphelion.
- The Earth rotates from West to East. is Correct: As established, the direction of the Earth's rotation is from West to East.
- The Earth's axis is perpendicular to the orbital plane. is Incorrect: The Earth's axis of rotation is not perpendicular to the orbital plane. It is tilted at an angle of 66½° to the plane of its orbit (orbital plane) and 23½° to the line perpendicular to the orbital plane.
Key Takeaway: The Earth rotates from West to East on an axis tilted at 66½° to its orbital plane, while revolving around the Sun in an elliptical orbit.
