he Earth exhibits two primary types of movement: rotation and revolution.
Rotation: The Earth rotates on its axis, which takes about 24 hours to complete. This rotation causes the cycle of day and night. The axis is an imaginary line running from the North Pole to the South Pole. Revolution: The Earth revolves around the Sun, taking approximately 365.25 days to complete one orbit. This revolution, combined with the tilt of the Earth’s axis, results in the changing seasons. |
How does the Earth’s rotation cause day and night? As the Earth rotates, different parts of the planet face the Sun, experiencing daylight, while the opposite side experiences night.
Why do we have seasons? The tilt of the Earth’s axis and its orbit around the Sun cause variations in sunlight, leading to seasonal changes.
What is the significance of the Earth’s tilt? The tilt affects the intensity and distribution of sunlight, creating seasonal differences in temperature and daylight.
