Examples include weathering, erosion, earthquakes, volcanoes, organisms a crack in the Earth's surface where two plates meet a process that constructs, or builds up an existing landform, or creates a new one. Examples include deposition, volcanoes, faults a mountain made of lava, ash, or other materials from eruptions the dropping of sediment, creates a new landform (deltas and sand dunes) a large tidal wave caused by an earthquake that happens under water A former "supercontinent" on the Earth that included all the present continents, which broke up and drifted apart how the movement of energy in an earthquake is measured 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 the melted, molten rock beneath Earth's surface the instrument used to measure the intensity of an earthquake the release of energy when plates shift the pieces of Earth's crust that fit together and form the top layer of the Earth 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 on Earth's surface that is directly above the focus of the earthquake the scale used to determine the strength of an earthquake (0-10.0 scale with 6.0+ being pretty powerful)
