Igneous, Metamorphic, and Sedimentary

Basaltic igneous rocks, are dense and dark-colored
Lava Magma when it has reached Earth's surface
Cementation Occurs when minerals such as quartz, calcite, and hematite are deposited between the pieces of sediment
Metamorphic Rock Rocks that have changed becuase of changes in temperature and pressure or the presence of hot, watery fluids
Compaction Pressure from the upper layers pushes down on the lower layers, if sediments are small, they can stick together and form solid rock
Nonfoliated Mineral grains grow and rearrange, but do not form layers
Extrusive igneous rocks that are formed as lava cools on the surface of the Earth
Rock mixture of rock fragments, volcanic glass, organic matter, or other natural materials
Foliated Mineral grains line up in parallel layers
Rock Cycle Illistrates the processes that create and change rocks
Granatic igneous rocks, are light-colored rocks of lower density than basaltic rocks
Sediment Loose materials such as rock fragments, mineral grains, and bits of shell that have been moved by wind, water, ice, or gravity
Igneous Rock When hot magma cools and hardens
Sedimentary Rock Forms when sediments are pressed and cemented together, or when minerals form from solutions
Intrusive Rocks that form from magma below the surface
