Examples include weathering, erosion, earthquakes, volcanoes, organisms how the movement of energy in an earthquake is measured a process that constructs, or builds up an existing landform, or creates a new one. Examples include deposition, volcanoes, faults area around the Pacific Ocean where there is a large number of earthquakes and some of the Earth's most active volcanoes occur the point underground where the energy buildup is released the pieces of Earth's crust that fit together and form the top layer of the Earth 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 instrument used to measure the intensity of an earthquake the scale used to determine the strength of an earthquake (0-10.0 scale with 6.0+ being pretty powerful) a crack in the Earth's surface where two plates meet a theory that explained how continents shift, or change position on Earth's surface a large tidal wave caused by an earthquake that happens under water the melted, molten rock beneath Earth's surface the release of energy when plates shift the molten rock when it reaches Earth's surface 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 mountain made of lava, ash, or other materials from eruptions
