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
