Rock Cycle Flashcards
(18 cards)
What are metamorphic rocks?
Rocks formed under intense heat and pressure from existing rocks.
What is the rock cycle?
The continuous process of rock formation and transformation.
What are igneous rocks?
Rocks formed from cooled magma or lava.
What are extrusive igneous rocks?
Igneous rocks that cooled above the surface (e.g. basalt).
What are intrusive igneous rocks?
Igneous rocks that cooled below the surface (e.g. granite).
What is weathering?
The process of breaking down rocks into smaller bits.
What is erosion?
The wearing away of rocks caused by rain.
What is transportation in the rock cycle?
The movement of eroded bits of rock around by wind and water.
What is deposition?
The laying down of sediment.
What is cementation?
The process of compressing layers to form sedimentary rocks.
What is metamorphism?
The process where heat and pressure transform rocks into metamorphic rocks.
What happens during melting?
Intense heating makes rocks partially melt, changing into magma.
What is cooling in the rock cycle?
The solidification of molten material to form igneous rocks.
What is exposure in the rock cycle?
The process of rocks being weathered and exposed again.
What is the role of uplift in the rock cycle?
The process that brings rocks to the surface.
What are sedimentary rocks?
Rocks formed from sediments through burial, compression, and cementation.
What are examples of exposed metamorphic rocks?
Marble is an example of exposed metamorphic rock.
What are examples of exposed sedimentary rocks?
Limestone is an example of exposed sedimentary rock.
