FAQs on Mindmap: Motions of the Earth - Social Studies (SST) Class 6

1. What are the main motions of the Earth?
Ans. The main motions of the Earth are rotation and revolution. Rotation refers to the Earth's spinning on its axis, causing day and night. Revolution refers to the Earth's movement around the Sun, completing one orbit in approximately 365.25 days.
2. How does the rotation of the Earth cause day and night?
Ans. The rotation of the Earth causes day and night because as it spins on its axis, different parts of the Earth are exposed to the Sun's light. The side facing the Sun experiences daylight, while the opposite side experiences darkness, resulting in the cycle of day and night.
3. Why does the Earth experience seasons?
Ans. The Earth experiences seasons due to its axial tilt. The axis of the Earth is tilted at an angle of approximately 23.5 degrees relative to its orbit around the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.
4. How long does it take for the Earth to complete one rotation?
Ans. It takes the Earth approximately 24 hours, or one day, to complete one rotation. This rotation causes the cycle of day and night.
5. What is the significance of the Earth's revolution around the Sun?
Ans. The Earth's revolution around the Sun is significant as it determines the length of a year and the changing seasons. It takes the Earth approximately 365.25 days to complete one revolution, resulting in the four seasons - spring, summer, autumn, and winter.
