Earth’s internal energies drive the activities of volcano, faults, folds, orogenesis and epeirogenesis. The planetary surface undergoes reshaping over geological time periods due to the effects of tectonics and erosion. The surface features built up or deformed through plate tectonics are subject to steady from precipitation, thermal cycles, and chemical effects. Glaciations, coastal erosion, the build-up of coral reefs, large meteorite impacts also act to reshape the landscape.
