Examples include deposition, volcanoes, faults the dropping of sediment, creates a new landform (deltas and sand dunes) the point underground where the energy buildup is released a crack in the Earth's surface where two plates meet the release of energy when plates shift A former "supercontinent" on the Earth that included all the present continents, which broke up and drifted apart the molten rock when it reaches Earth's surface a natural occurrence that breaks down the surrounding area. Examples include weathering, erosion, earthquakes, volcanoes, organisms how the movement of energy in an earthquake is measured the melted, molten rock beneath Earth's surface the pieces of Earth's crust that fit together and form the top layer of the Earth the scale used to determine the strength of an earthquake (0-10.0 scale with 6.0+ being pretty powerful) a mountain made of lava, ash, or other materials from eruptions a large tidal wave caused by an earthquake that happens under water organisms can be destructive as they eat away and/or destroy or change the landscape of the world the point on Earth's surface that is directly above the focus of the earthquake a theory that explained how continents shift, or change position on Earth's surface area around the Pacific Ocean where there is a large number of earthquakes and some of the Earth's most active volcanoes occur
