The Rock Cycle
How is magma formed?
Formed when rock partially or completely melts, happens when metamorphic rock comes in contact with magma and then melts and becomes part of the magma.
How does metamorphic rock form magma and lava?
Heat (melting).
How does sedimentary rock form magma and lava?
Heat (melting).
How does igneous rock form metamorphic rock?
Heat and pressure (metamorphism)
How does igneous rock form magma and lava?
Heat.
What is new rock formed from?
New rock is constantly formed from old rock through the process of the rock cycle.
Does a rock only take one pathway in the rock cycle?
Rocks can follow various pathways in the rock cycle.
rock
a naturally occurring solid mixture of one or more minerals and organic matter
What does the location of the rock determine?
The location of the rock determines which natural forces will have the greatest impact on the process of change (e.g. the rock on the surface will be more affected by heat and pressure)
What is the Rock Cycle?
The series of processes in which rock forms, changes from one type of rock to another, is destroyed, and is formed again by geological process.
What are the three types of rock?
Sedimentary, metamorphic, and igneous.
metamorphism
(heat & pressure) sediment under the ground can be squeezed by the sediment above it, if the temperature and pressure are high enough a new kind of rock forms: in some cases the rock even melts
How is metamorphic rock formed?
At great depth below the earth, intense heat and pressure squeeze the sedimentary rock and change into metamorphic rock.
How does magma and lava form igneous rock?
Cooling and solidification after volcanic activity.
How does sediment form sedimentary rock?
Deposition, compacting, and cementing.
How is igneous rock formed?
Magma tends to be less dense than the surrounding rock so it rises and cools forming igneous rock.
How does sedimentary rock form metamorphic rock?
Metamorphism.
How is sedimentary rock formed?
Sediment is eroded from the hills and mountains and washed down a river to the ocean, over time thick layers are formed on the ocean floor and are compressed into sedimentary rock.
How is sediment formed?
Uplift & erosion expose the igneous rock on the surface that then experiences weathering and becomes sediment that is eroded and the cycle begins again.
How does igneous rock form sediment?
Weathering and erosion.
How does metamorphic rock form sediment?
Weathering and erosion.
How does sedimentary rock form sediment?
Weathering and erosion.
What are four processes "That Shape the Earth"?
Weathering, erosion, deposition, and metamorphism.
deposition
the process by which material moved by erosion is dropped (deposited) in another location
erosion
the process by which wind, water, ice, or gravity transport soil and sediment from one location to another
weathering
the process in which water, wind, ice, and heat break down rock
