A naturally occurring solid mixture of one or more minerals or organic matter.
Rock Cycle
The series of processes in which a rock forms, changes from one type to another, is destroyed, and forms again by geological processes.
Sedimentary Rock
Rocks made from sediments and mineral fragments. (forms in layers)
The process in which water, wind, ice, gravity, and heat breaks down.
The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.
The process in which material is laid down.
After sediments are deposited, the sediments are pressed together.
After sediments are compacted, they are cemented together by minerals that dissolve in water.
The chemical makeup of a rock; describes either the minerals or other materials in the rock.

Igneous Rock
Forms when hot, liquid rock, or magma (lava), cools and becomes a solid.
Located beneath the Earth's surface.

Intrusive Igneous Rock

Extrusive Igneous Rock
Rock that forms as a result of volcanic activity at or near the Earth's surface.
Layers of rock/the process in which sedimentary rocks are arranged in layers.
Clastic Sedimentary Rock
Rock that forms from rock or mineral fragments called clasts, are cemented together.
Chemical Sedimentary Rock
Rocks that form when minerals crystallize out of a solution, such as sea water.
Organic Sedimentary Rock
Rocks that form from the remains of once-living plants and animals.
Metamorphic Rock
All types of rocks can undergo heat and pressure to create a metamorphic rock.
The texture of metamorphic rock in which the mineral grains are arranged in planes or bands.
The texture of metamorphic rocks in which the mineral grains are not arranged in planes or bands.
