Examples include weathering, erosion, earthquakes, volcanoes, organisms the scale used to determine the strength of an earthquake (0-10.0 scale with 6.0+ being pretty powerful) organisms can be destructive as they eat away and/or destroy or change the landscape of the world the pieces of Earth's crust that fit together and form the top layer of the Earth the instrument used to measure the intensity of an earthquake the molten rock when it reaches Earth's surface the release of energy when plates shift area around the Pacific Ocean where there is a large number of earthquakes and some of the Earth's most active volcanoes occur a process that constructs, or builds up an existing landform, or creates a new one. Examples include deposition, volcanoes, faults the point on Earth's surface that is directly above the focus of the earthquake a mountain made of lava, ash, or other materials from eruptions a theory that explained how continents shift, or change position on Earth's surface the melted, molten rock beneath Earth's surface the dropping of sediment, creates a new landform (deltas and sand dunes)
