Constructive and Destructive Forces Study Guide Constructive Forces Processes that create landforms (deposition, landslides, volcanic eruptions, floods Destructive Forces Processes that wear away and break down landforms Landslide constructive/ They are mass movements of land due to destructive gravity Flood constructive/ Occur when a large amount of water covers destructive land that is usually dry Volcanoes constructive/ are mountains with openings in Earth’s crust destructive through which magma, gases, and ash reach Earth’s surface Deposition constructive The dropping, or depositing, of sediments by water, wind, or ice. Erosion destructive The movement of sediments and soil by wind, water, ice, and gravity. Earthquakes destructive Weathering destructive Vibrations on Earth’s surface caused by sudden movement in Earth, often along a fault, a break in Earth’s surface. A general term used to describe processes that break down rocks at or near the surface of the earth Physical Weathering destructive A type of weathering that causes change in the size or shape of rocks without changing the chemical makeup of the rock Chemical Weathering destructive A type of weathering that causes a change in the minerals that makeup of the rock. Oxygen, carbon dioxide and acids cause chemical weathering.
