- Electromagnetic radiation (primarily from the Sun): Drives climate, weather systems, erosion (through wind, water, ice), photosynthesis (biological weathering), and thermal expansion/contraction (physical weathering). - Geothermal energy: Drives plate tectonics, volcanic activity, earthquakes, formation of mountains and ocean basins, and heat flow influencing subsurface processes. - Gravitational force: Causes mass movements (landslides, rockfalls), erosion by rivers (pulling water downhill), formation of tides (along with moon), and influences atmospheric circulation and ocean currents. - Plate movements: Directly responsible for earthquakes, volcanism, mountain building (orogeny), creation of rift valleys, and continental drift, constantly reshaping the Earth's crust. - Rotation of the earth: Causes Coriolis effect (influencing weather patterns, currents), contributes to tides (along with gravity), and diurnal temperature variations causing weathering. - Revolution of the earth: Along with axial tilt, causes seasons, influencing weather patterns, rates of weathering and erosion, formation and melting of ice/snow, and biological activity.
Consider the following: Electromagnetic radiation 1. Geothermal energy 2. Gravitational force 3. Plate movements 4. Rotation of the earth 5. Revolution of the earth 6. Which of the above are responsible for bringing dynamic changes on the surface of the earth?
