The Rock Cycle

Dissolved minerals and particles of sediment that stick together to form sedimentary rock in this process.

Cementation

When seas or lakes evaporate, a type of sedimentary rock called ________ can form.

Chemcial

Layer upon layer of sediments are deposited and pressed together.

Compaction

Skeletons of tiny ocean animals that grow together and are only found in warm, clear ocean waters.

Coral reef

Sediment settles out of moving water by this process.

Deposition

The carrying away of rock fragments by water, wind, or ice. This is an important process in the formation of sedimentary rocks.

Erosion

What step in the rock cycle creates the sediment from which sedimentary rock is formed?

Erosion

An igneous rock that is formed from lava.

Extrusive rock

Texture of slate because its mineral particls can be seen only with a microscope.

Fine grained

Chemical reactions, pressure, and _________ cause sedimentary rock to change to metamorphic rock.

Heat

Describe two pathways through the rock cycle in which igneous rock can become metamorphic rock.

Heat and pressure

In the rock cycle, what happens to magma and lava when they cool and harden?

Igneous Rock

Some of the sedimentary rock tht is made from ancient coral reefs buried by sediments.

Limestone

Melted rock that moves upward when oceanic plates move apart in the rock cycle.

Mantle

In the rock cycle, what forces could cause a metamorphic rock to become magma?

Melting

Foliated and nonfoliated are terms used to describe the texture of this type of rock.

Metamorphic rock

Most sedimentary rock become metamorphic rock before it can become magma?

No, because igneous rocks can also melt

Metamorphic rocks such as marble and quarzite are _______ because the mineral grains are not arranged in parallel layers or bands.

Nonfoliated

Coal is an example of what type of rock which is a sedimentary rock that forms where thick layers of plant and animal remains are depposited.

Organic

The series of processes that slowly changes rocks from one kind to another kind.

Rock cycle

Small, sold pieces of material that come from rocks or living things.

Sediments

Describe a pathway through the rock cycle in which magma becomes sedimentary rock.

Volcanic activity and erosion
