The series of processes that change one type of rock into another type of rock.

• Rock Cycle

• Compaction

• Cementation

A type of igneous rock that generally contains large crystals and forms when magma cools slowly beneath Earth's surface.

• Minerals

• Extrusive

• Intrusive

• Sediments

Fine-grained igneous rock that forms when magma cools quickly at or near Earth's surface.

• Minerals

• Intrusive

• Extrusive

• Sediments

Loose materials such as rock fragments, minerals grains, and bits of shell that have been moved by wind, water, ice or gravity.

• Igneous Rock

• Sediments

• Intrusive

• Extrusive

The type of weathering in which rock is physically broken into smaller pieces

• erosion

• chemical weathering

• mechanical weathering

Chemical reactions dissolve or alter the minerals in rocks to change them into different materials.

• Erosion

• mechanical weathering

• chemical weathering

Which of the following would be an example of mechanical weathering?

• frost wedging

• oxidation/rusting

• water and carbon mixing to form a weak acid mixture

• water dissolving certain minerals in rock

Which of the following would be an example of chemical weathering by oxidation?

• A rodent digging a hole in the soil.

• Metal that is stored outside that begins to rush and change color

• roots from a tree that start to push their way through rocks

• frost wedging

The process of sediment or soil being picked up or moved is:

• weathering

• breaking down

• erosion

• sedimentation
