The sun rises in East and sets in West direction.

Explanation:

1. Sun's Movement
The sun appears to move across the sky from east to west due to the rotation of the Earth on its axis. This rotation causes the sun to rise in the east and set in the west every day.

2. Earth's Rotation
The Earth rotates on its axis from west to east, which is why the sun appears to rise in the east and set in the west. This rotation takes approximately 24 hours to complete, resulting in the cycle of day and night.

3. Sunrise
Sunrise is the moment when the upper edge of the sun becomes visible above the horizon in the east. It marks the beginning of a new day. As the Earth rotates towards the east, the sun gradually rises higher and illuminates the sky with its light.

4. Sunset
Sunset is the moment when the upper edge of the sun disappears below the horizon in the west. It indicates the end of the day and the transition into night. As the Earth continues to rotate towards the east, the sun gradually descends and eventually disappears from view.

5. East-West Axis
The directional terms of east and west are based on the Earth's east-west axis. When facing north, east is on the right side and west is on the left side. Therefore, the sun rises in the east, moves across the sky during the day, and sets in the west.

Conclusion:
In conclusion, the sun rises in the east and sets in the west direction due to the rotation of the Earth on its axis. This daily cycle of sunrise and sunset marks the beginning and end of each day.
