Explain with illustrations and diagrams the effects of Earth’s rotation.
The effects of the Earth’s rotation are as follows:
- Occurrence of day and night: The rotation of the Earth around its axis causes the occurrence of day and night. As the Earth rotates towards the east, the side facing the Sun experiences day while the side facing away from the Sun experiences night. This phenomenon occurs every 24 hours, which is the time it takes for the Earth to complete one rotation.
- Apparent daily movement of the sun: Due to the rotation of the Earth, the Sun appears to move across the sky on a daily basis. The apparent daily movement of the Sun is from east to west. This is because the Earth is rotating towards the east, causing the Sun to appear to move towards the west.
- Determination of direction: The Earth’s rotation also helps in determining direction. The rotation of the Earth causes the apparent movement of the Sun and stars across the sky, which is used to determine direction. For example, the position of the Sun in the sky can be used to determine east and west, while the position of the North Star can be used to determine north.
