– 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.
