Unit 5 Lesson 3

Earth Science

TermDefinition
Deposition constructive placement of weathering rock and other materials in anew place/ location due to water, wind, etc.
Weathering the weathering down of rock over time by natural elements like rain, wind and sun. A slow destructive force that wears down and breaks rock into smaller pieces called sediments. two types of weathering are mechanical or chemical or chemical (physical)
Mass wasting downhill movement of a large mass of rocks or soil due to gravity
Destructive forces forces that destroy land forms through erosion and weathering, ice, earthquakes. constructive forces happen slowly by deposition
processes series of actions or openations that lead to an end result.
composition the was in which something is put together from different parts
Erosion the destructive movement of materials from one place to another by wind water ice gravity and other natural forces and the move ment by small pieces of rock or sediment.
Landforms a natural feature of the earths surface. Examples include mountains valleys plains and hills.
constructive forces forces that build up an existing land form or create a new one through deposition examples gravity wind volcanoes water ice earthquakes. Constructive forces happen slowly by deposition
landslide a mass of earth rocks and debris that quickly and suddenly falls down the side of a mountain cliff hill etc.
Gravity The force on our planet that pulls things toward the center of the planet. Its what makes things fall you let go of them. All planets and stars have this force
reaction In chemistry the change that happens when two or more substances act on each other to form a different substance.
Physical (mechanical) weathering physical or mechanical weathering is the process of breaking down of rocks and soils through direct contact with atmosphere conditions such as heat ice and pressure. the composition of the rock does not change
Sediment minerals or organic matter carried and deposition by water or wind that may consolidate into rock.
Chemical weathering chemical weathering is the direct effect of atmosphere or biological chemicals in the breakdown of rocks soils and minerals
Delta triangular deposit of sediment that forms where a stream entens a large body of water
glacier a large slow moving mass of ice nearly 70 percent of earths surface is stored in huge bodies of ice called glaciers
