Direction of Earth's Rotation: West to East

The rotation of the Earth is the spinning motion of the planet around its axis. This rotation determines the length of the day and night cycle. The Earth takes approximately 24 hours to complete one full rotation.

Rotation Axis
- The Earth's rotation axis is an imaginary line that runs through the North and South Poles.
- It is tilted at an angle of about 23.5 degrees in relation to its orbit around the Sun.

Effect of Earth's Rotation on the Sun's Movement
- The Sun appears to rise in the east and set in the west due to the Earth's rotation.
- As the Earth rotates from west to east, the Sun appears to move across the sky from east to west.
- This is why the Sun rises in the eastern horizon and sets in the western horizon.

Reason for Earth's Rotation
- The Earth's rotation is believed to have originated from the gravitational collapse of the solar nebula, which formed the Sun and the planets.
- The conservation of angular momentum during this collapse caused the spinning motion of the Earth.
- This rotational motion has been maintained ever since.

Coriolis Effect
- The rotation of the Earth also gives rise to the Coriolis effect, which affects the movement of fluids and objects on the Earth's surface.
- The Coriolis effect causes moving air masses, such as winds, to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
- This effect also influences the direction of ocean currents and other large-scale atmospheric and oceanic phenomena.

Conclusion
In conclusion, the Earth rotates from west to east. This rotation is responsible for the daily cycle of sunrise and sunset. The rotation axis of the Earth is tilted, causing the Sun to appear to move across the sky from east to west. The Earth's rotation also gives rise to the Coriolis effect, which affects various atmospheric and oceanic phenomena.
