This is what molten rock is called when it is under the earth's surface.
Magma
100
What is the area beneath a volcano where large amounts of magma build up?
Hot spot
100
What are the three types of rocks?
Metamorphic; igneous; sedimentary
100
This type of volcano is steep and high.
Composite volcano
100
A shield volcano is flat because the lava that formed it is ______________________.
thin, "watery", or "liquidy"
200
This is what molten rock is called when it is above the earth's surface.
Lava
200
These are igneous rocks that are formed by cooling on the surface of the earth.
Extrusive igneous rocks
200
Sedimentary rock transforms into metamorphic rock because of ____________ and ______________.
heat ; pressure
200
This type of volcano is wide and has a broad slope.
Shield volcano
200
A composite volcano is steep and high because the lava that formed it is _________________.
thick or "clumpy"
300
This type of rock is formed from cooled lava or magma.
Igneous rock
300
These are igneous rocks that cool and form inside of the earth.
Intrusive igneous rocks
300
Metamorphic rock first ____________ and turns into magma. Then it ____________ and turns into igneous rock.
melts ; cools
300
This type of volcano is the smallest. It also has a bowl-shaped crater at the top.
Cinder cone volcano
300
When metamorphic rock melts and turns into magma, where does the heat come from that makes the rock melt?
the core of the earth
400
This type of rock is formed from intense heat and pressure.
Metamorphic rock
400
This is lava that cools almost immediately on the ocean floor when it is exposed to the cold water.
Pillow lava
400
_____________ causes rocks to break into pieces called sediment. _____________ is the process of the sediment being carried away by wind and rain water.
Weathering ; erosion
400
Viscous (thick and clumpy) lava would make a ______________ volcano.
composite
400
Erosion is the process of sediment being carried away to a body of water. How does it get carried away?
wind and rain water
500
This type of rock is formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans.
Sedimentary rock.
500
The state of being thick, sticky, and semifluid in consistency.
Viscosity
500
________________ and ________________ is the process of sediment falling to the bottom of a body of water and forming layers.
compaction and cementation
500
Non-viscous (thin and "watery") lava would make a _____________________ volcano.
