Term
Igneous
Definition
The type of rock that forms when hot, liquid rock cools and hardens
Term
Sedimentary
Definition
The type of rock that forms when rocks are broken down into smaller pieces that harden into new rock.
Term
Weathering
Definition
When water, Ice, Wind, and Heat break down
Term
Weathering
Definition
When water, Ice, Wind, and Heat break down
Term
metifomifc
Definition
The type of rock that forms when heat and pressure squeeze sedimentary rock, but do not melt it.
Term
Depision
Definition
When water, ice, wind, and gravity drop newly formed sediments
Term
texture
Definition
the size, shape and position of minerals in a rock
Term
Cemented
Definition
Individual grains of sedimentary rock are held together.
Term
Cource Grained
Definition
are formed when magma cools slowly deep inside the earth with large crystals
Term
Mantle
Definition
The compositional layer that makes up most of the Earths mass.
Term
tectonic plates
Definition
Large slabs of lithosphere that move around on the asthenosphere
Term
outer core
Definition
Is the liquid core of the earths core
Term
Compression
Definition
The type of stress in which objects are squeezed together and creates anticlines and scnclines.
Term
uplift
Definition
the process by which regions of the crust are raised to higher elevations.
Term
Volcanic Mountians
Definition
Mountians that form when molten rock erupts onto the Earths surface.
Term
lithospere
Definition
The structural layer that is the hard outermost layer of the Earth.
Term
Global Positioning System
Definition
Scientists use this to measure the rate of tectonic plate movement .
Term
Crust
Definition
Is the outermost compositional layer of the Earth.
Term
Density
Definition
This helps determine the speed of ssismic waves
Term
folded mountians
Definition
These form when rock layers are squeezed together and pushed upward.
Term
folding
Definition
This occurs when rock layers bend because of stress in the earths crust.
Term
faults
Definition
These occur when rock layers break because of stress from compression or tension.
Term
Fault-Normal
Definition
When rocks are pulled apart by tension.
Term
Fault-Reverse
Definition
When rocks are pushed together by compression.
