Match the following geological processes with their definitions:

Weathering = Breakdown of rocks into smaller fragments Lithification = Process of turning sediment or other material into stone Compaction = Process of sediments being pressed more closely together by the weight of sediments above or by tectonic forces Cementation = Process found in porous sediment, when water deposits minerals that gradually fill the spaces between grains and bind them to one another to form rock Signup and view all the answers

Match the following geological terms with their descriptions:

Sediment = Solid material, moved by wind, water, and other forces, that settles on the surface of land or the bottom of a body of water Pressure = Force exerted per unit area by many particles of a gas randomly striking the walls of its container Magma = Melted rock located beneath Earth's surface Weathering = Breakdown of rocks into smaller fragments Signup and view all the answers

Match the following terms with their role in the rock cycle:

Weathering = Initial breakdown of rocks into smaller fragments Transport = Movement of small particles to other locations by wind, water, ice, and gravity Lithification = Turning sediment or other material into stone Magma = Melted rock located beneath Earth's surface Signup and view all the answers
