FAQs on Motion of the Earth Video Lecture - NCERT Video Summary: Class 6 to Class 12 (English) - UPSC
| 1. What is the motion of the Earth? |  |
Ans. The motion of the Earth refers to the movement of our planet in various ways. It has two main motions - rotation and revolution. Rotation is the Earth spinning on its axis, causing day and night. Revolution is the Earth's movement around the Sun, which takes approximately 365.25 days, resulting in different seasons.
| 2. How does the rotation of the Earth affect day and night? | |
Ans. The rotation of the Earth on its axis causes day and night. As the Earth rotates, different parts of it face towards or away from the Sun, resulting in the alternation between daylight and darkness. When a particular region is facing the Sun, it experiences daytime, while the region facing away from the Sun experiences night.
| 3. Why does the Earth experience different seasons due to its revolution? | |
Ans. The Earth experiences different seasons due to its revolution around the Sun. The axis of the Earth is tilted at an angle of about 23.5 degrees relative to its orbit. This tilt causes the Sun's rays to hit different parts of the Earth more directly at different times of the year, leading to variations in the amount of sunlight and temperature, which result in the four seasons - spring, summer, autumn, and winter.
| 4. How long does it take for the Earth to complete one full revolution around the Sun? | |
Ans. It takes the Earth approximately 365.25 days to complete one full revolution around the Sun. This period is known as a tropical year or a solar year. To account for the extra quarter day, a leap year with 366 days is added every four years, ensuring that our calendar remains synchronized with the Earth's revolution.
| 5. What would happen if the Earth stopped rotating? | |
Ans. If the Earth were to suddenly stop rotating, the consequences would be catastrophic. The Earth's rotation helps create the centrifugal force that counteracts gravity, keeping objects on the surface. If this force were to disappear, everything on the Earth's surface would be thrown into the atmosphere, resulting in extreme winds, massive tsunamis, and devastating destruction. Additionally, there would be a significant impact on weather patterns, causing drastic changes in climate.
