Granitic Describes generally light-colored silica rich igneous rock that is less dense than basaltic rock.
Lava Molten rock that flows from volcanoes onto Earth's surface.
Igneous rock Rock formed when magma or lava cools and hardens.
Intrusive Describes a type of igneous rock that generally contains large crystals and forms when magma cools slowly beneath Earth's surface.
Non-foliated Mineral grains grow and rearrange but they dont form layers.
Metamorphic rock Rocks that have changed because of changes in temperature and pressure or the presence of hot, watery fluids.
Extrusive Describes fine-grained igneous rock that forms when magma cools quickly at or near Earth's surface.
Rock A mixture of such minerals rock fragments, volcanic glass organic matter or other natural materials.
Rock cycle To show how rocks slowly change through time.
Sediments Loose materials such as rock fragments, mineral grains, and bits fo shell that have been moved by wind, water, ice, or gravity.
Sedimentary rock Forms when sedements are pressed and cemented together, or when minerals form from solutions
