More Rocks
100
The process by which one rock changes into another.
rock cycle
100
What occurs when movement of rock beneath Earth's surface causes the ground to shake?
earthquake
100
These form when sedimentary rock layers are squeezed together and they push upward. Example - the Rockies.
folded mountains
100
Molten material that erupts onto Earth's surface.
lava
100
This type of rock forms when particles of rocks or the remains of plants and animals are pressed and cemented together in layers.
sedimentary rock
200
This rock forms when molten rock cools at or below Earth's surface.
igneous rock
200
Vibrations that move through the ground carrying the energy released during an earthquake are called ______________.
seismic waves
200
Most of these form at convergent boundaries when molten rock erupts onto Earth's surface.
volcanoes or volcanic mountains
200
This area of volcanic activity does not form near a tectonic plate boundary. What is it?
hot spot
200
The name of the process when sediments are pressed together is called _____.
compaction
300
Chemical changes, heat, and pressure deep beneath Earth's surface can change any rock into this type of rock.
metamorphic rock
300
Name the seismic waves that travel along the ground and cause the most destruction.
surface waves
300
A huge hole left behind by the collapse of a volcanic mountain is called _____________.
caldera
300
This volcano is made from quiet eruptions and has a curved surface.
shield volcano
300
Name the process that occurs when weathered rock fragments are carried away by water, wind, or ice.
erosion
400
When magma cools below Earth's surface, ______________ rock forms.
intrusive igneous rock
400
The point, deep beneath the Earth, where an earthquake begins is called the_____________.
focus
400
A large area of flat land that is elevated high above sea level. It is wider than it is tall.
plateau
400
Name the type of volcano that is made entirely of pyroclastic material (ash,cinders, and bombs).
cinder cone volcano
400
This is the process when dissolved minerals crystallize and glue particles of sediment together.
cementation
500
Name the type of rock that forms when lava cools at or above Earth's surface.
extrusive igneous rock
500
During an earthquake, the point on Earth's surface, directly above the focus is called the _____________.
epicenter
500
These form when several normal faults cause large blocks of Earth's crust to lift up, relative to the rest of the blocks.
fault-block mountains
500
This volcano is made from explosive eruptions of pyroclastic material followed by outpourings of lava.
composite (strato) volcano
500
Name the process when sediment settles out of the water or wind, which is carrying it. The sediments then sink to the bottom of a lake or river.
