FAQs on Motions of the Earth : Overview Video Lecture - Social Studies (SST) Class 6
| 1. What are the motions of the Earth? |  |
Ans. The motions of the Earth refer to the various movements that the Earth undergoes. These include rotation, revolution, and precession. Rotation refers to the spinning of the Earth on its axis, which causes day and night. Revolution refers to the Earth's movement around the Sun, which takes approximately 365.25 days and causes the change of seasons. Precession refers to the slow wobbling motion of the Earth's axis, which completes a full cycle in about 26,000 years.
| 2. How does the rotation of the Earth cause day and night? | |
Ans. The rotation of the Earth on its axis causes day and night. As the Earth rotates, different parts of the planet are either facing towards the Sun (day) or facing away from the Sun (night). When a particular region is facing towards the Sun, it experiences daylight, while the region facing away from the Sun experiences darkness, resulting in night. The Earth completes one full rotation in approximately 24 hours, leading to alternating periods of day and night.
| 3. What is the significance of the Earth's revolution? | |
Ans. The Earth's revolution is significant because it determines the length of a year and the occurrence of seasons. The Earth revolves around the Sun in an elliptical orbit, taking approximately 365.25 days to complete one revolution. This revolution causes the change in the Earth's position relative to the Sun, resulting in different seasons. When the hemisphere is tilted towards the Sun, it experiences summer, while when it is tilted away, it experiences winter. The revolution also helps in maintaining a stable climate and providing the appropriate conditions for life on Earth.
| 4. How does the precession of the Earth's axis affect us? | |
Ans. The precession of the Earth's axis refers to the slow wobbling motion of the Earth's axis. This motion affects the tilt of the Earth's axis, which has a significant impact on the Earth's climate. Over a period of about 26,000 years, the axis completes a full cycle of precession. As a result, the orientation of the Earth's axis changes, altering the position of the poles relative to the celestial sphere. This, in turn, affects the distribution of sunlight and the intensity of seasons. However, the impact of precession on our daily lives is minimal, as its effects are observed over long periods.
| 5. How do the motions of the Earth contribute to the concept of time? | |
Ans. The motions of the Earth play a crucial role in the concept of time. The rotation of the Earth on its axis determines the length of a day, with one complete rotation taking approximately 24 hours. The revolution of the Earth around the Sun determines the length of a year, with one complete revolution taking around 365.25 days. These motions are used as the basis for the measurement of time, with days and years being fundamental units. The motions of the Earth also influence the concept of time zones, as different regions experience different times based on their position relative to the Sun.
