Examples include weathering, erosion, earthquakes, volcanoes, organisms a theory that explained how continents shift, or change position on Earth's surface the point underground where the energy buildup is released a process that constructs, or builds up an existing landform, or creates a new one. Examples include deposition, volcanoes, faults the molten rock when it reaches Earth's surface the pieces of Earth's crust that fit together and form the top layer of the Earth A former "supercontinent" on the Earth that included all the present continents, which broke up and drifted apart the release of energy when plates shift
