The Earth’s rotation results in the day and night cycle causing the apparent movement of the Sun across the sky. Therefore, the Sun rises in the east and sets in the west.

• The Sun rises in the east and sets in the west.
• The Sun rises in the northeast and sets in the northwest.
• The Sun rises in the north and sets in the south.
• The Sun rises in the west and sets in the east.
