Consider the following:
- 1.Electromagnetic radiation
- 2.Geothermal energy
- 3.Gravitational force
- 4.Plate movements
- 5.Rotation of the earth
- 6.Revolution of the earth
Which of the above are responsible for bringing dynamic changes on the surface of the earth?
- A.1, 2, 3 and 4 only
- B.1, 3, 5 and 6 only
- C.2, 4, 5 and 6 only
- D.1, 2, 3, 4, 5 and 6
▶ Answer & Explanation
Correct answer: D. 1, 2, 3, 4, 5 and 6
Dynamic changes on the Earth's surface are driven by both endogenic (internal) and exogenic (external) forces. Internal forces like geothermal energy and plate movements cause processes like earthquakes, volcanoes, and mountain formation. External forces, influenced by solar radiation and gravitational pull, manifest as weathering, erosion, and deposition, shaping landforms over time. Earth's rotation and revolution also play roles in phenomena like climate patterns and diurnal/seasonal changes that indirectly affect surface processes.
