Dynamic Changes on Earth's Surface
Question

Which of the above are responsible for bringing dynamic changes on the surface of the earth?
- 1.
Electromagnetic radiation
- 2.
Geothermal energy
- 3.
Gravitational force
- 4.
Plate movements
- 5.
Rotation of the earth
- 6.
Revolution of the earth
Options
1, 2, 3 and 4 only
1, 3, 5 and 6 only
2, 4, 5 and 6 only
1, 2, 3, 4, 5 and 6
Explanation
All six factors are responsible for dynamic changes on Earth's surface. Item 1: Electromagnetic radiation (solar energy) drives weathering, erosion, and climate processes. Item 2: Geothermal energy powers volcanism, plate tectonics, and crustal movements. Item 3: Gravitational force drives ocean tides, river flow, and mass movements. Item 4: Plate movements cause earthquakes, mountain building, and crustal deformation. Item 5: Earth's rotation causes wind patterns, ocean currents (Coriolis effect), and day-night cycles affecting processes. Item 6: Earth's revolution causes seasonal changes, climate variations, and affects weathering/erosion rates. All these factors, both endogenic (internal) and exogenic (external), contribute to continuous dynamic changes on Earth's surface.
