Examples include deposition, volcanoes, faults a mountain made of lava, ash, or other materials from eruptions the molten rock when it reaches Earth's surface the scale used to determine the strength of an earthquake (0-10.0 scale with 6.0+ being pretty powerful) the point on Earth's surface that is directly above the focus of the earthquake the dropping of sediment, creates a new landform (deltas and sand dunes) the release of energy when plates shift the melted, molten rock beneath Earth's surface the point underground where the energy buildup is released a crack in the Earth's surface where two plates meet the instrument used to measure the intensity of an earthquake the pieces of Earth's crust that fit together and form the top layer of the Earth organisms can be destructive as they eat away and/or destroy or change the landscape of the world A former "supercontinent" on the Earth that included all the present continents, which broke up and drifted apart a natural occurrence that breaks down the surrounding area.
