Erosion • A destructive process where materials are removed from the surface of the Earth and then deposited elsewhere.
Weathering • A destructive process where rocks, soil, and minerals are broken down through contact with atmospheric conditions. (physical and chemical weathering) • Physical Chemical
Deposition • A constructive process where sediments are added to land build it up from previously eroded sediments

Deltas • A landform that is formed at the mouth of a river where it flows into another body of water and sediments are deposited there. Which Landform is delta? A. B. C. D. 1 2 3 4
Moraines • An accumulation of soil and rock that is formed by moving glaciers Which Landform is a moraine? A. B. C. D. 1 2 3 4
Earthquakes • A constructive process that results in a sudden release of energy in the Earth’s crust where plates slip and move and displacement of land occurs. • Before: After: The earthquake that hit Japan in 2011 moved the coast line.
Volcanoes • A constructive process where an opening in the Earth’s surface ruptures and allows magma, ash, and gases to escape.
