Review
This process breaks rocks into smaller pieces at Earth’s surface without changing their chemical composition.
Weathering
This heat transfer process moves material in circular currents inside Earth’s mantle.
Convection
This process moves rock particles from one place to another by wind, water, gravity, or ice.
Erosion
When layers of sediment build up in oceans over long periods of time, this type of rock is most likely forming.
Sedimentary Rock
These two forces deep inside Earth can transform sedimentary rock into metamorphic rock.
Heat and Pressure
A rock that forms from layers of sand, shells, or small rock fragments is most likely this type of rock.
Sedimentary Rock
Cooling and this crystal-forming process must occur for magma to become solid rock.
Crystallization
The rock cycle shows that any rock can eventually become this molten material beneath Earth’s surface.
Magma
When sediments are dropped by wind, water, or ice in a new location, this process is occurring.
Deposition
When existing rock is buried deep underground and exposed to intense heat but does not melt, it becomes this type of rock.
Metamorphic Rock
This step in sedimentary rock formation happens after deposition and helps glue sediments together.
Cementation
The weight of overlying sediments increasing pressure on buried rock is an example of this rock cycle force.
Pressure
This type of rock forms when magma or lava cools and hardens.
Igneous Rock
This must happen to any rock type before it can become magma.
Melting
This best describes the rock cycle: rocks are constantly doing this over time.
Changing from one type to the other (old rock to new rocks)
Before sediments can become sedimentary rock, they must first experience these two things
Compaction and Cementation
If lava cools quickly at Earth’s surface after a volcanic eruption, it forms this type of igneous rock.
Extrusive Igneous rock
If a sedimentary rock is located next to a magma chamber and changes form without melting, this likely caused it.
