lithification
the physical process that transforms the sediments into sedimentary rocks
erosion
the transport of pieces of rock by wind water or glaciers
sediments
pieces of a solid material that are deposited by water wind or glaciers
lineation
the alignment of rocks
mohs scale
used for testing the hardness of a mineral
weathering
the break up of rocks such as frost wedging or wave action
hardness
a measure of how easily a mineral can be scratched
streak
the color of a mineral when it is broken up and powdered
cooling rates on the grain size of igneous rocks
the slower the grain cools, the bigger the grain size in the rock will be
oxygen
most abundant element in the earth's crust
intrusive rock
coarse grained igneous rocks that cool slowly beneath the earth's surface
deposition
where the sediments are laid down or sink to the bottom of a body of water
3000
number of types of minerals found in the earth's crust
foliated
a metamorphic rock with wavy layers cause by high pressure
sedimentary rocks
sediments get deposited, compressed and lithified
metamorphism
when rocks undergo heat and pressure without melting
magma
a slushy mix of molten rocks, gases, and mineral crystals
three ways metamorphic rocks are formed
contact, regional and hydrothermal
extrusive rock
fine grained igneous rocks that cool quickly on earths surface
earthquakes
the boundaries of two plates rubbing together
lava
magma that flows out onto earth's surface
igneous rock
formed from the crystallization of magma
cleavage and fracture
describes how minerals break apart
