Earth Science Constructive and Destructive Forces Chapter 2

• Processes or forces that create new landforms • Constructive forces

• An area of new • delta land at the mouth of a river.

• The process of • Deposition dropping or depositing sediment in a new location

• Processes or forces that destroy the surface of the earth • Destructive forces

• A shaking of earth’s surface caused by movement of rock in earth’s crust • earthquake

• The process of • erosion moving sediment by wind, moving, water, or ice

• A crack in the earth’s crust • fault

• A natural land shape or feature • landform

• Molten rock from beneath the earth • magma

• A type of erosion that occurs when gravity causes huge amounts of soil or rock debris to be carried down a slope. • Mass movement

• the process of breaking down rock by natural means • weathering

• A mountain that • volcano forms as molten rock flows through a crack in earth’s surface

• Molten rock that flows through a volcano onto earth’s surface • lava

• A section of • plate earth’s crust and mantle that fits together with other sections like puzzle pieces

A hill of sand that is made up and shaped by wind • Sand dune

• A large hole formed when the roofs of caves collapse • sinkhole

• A wall like structure • jetty that sticks out into the ocean to prevent sand from being carried away

• Surface landforms of an area • topography
