what two things are ignouse rocks made of
magma and lava
100
Metamorphic rocks
Metamorphic rocks are ether foliated or nonfoliated
100
Sedimentary rocks
Sedimentary rocks form from weathering and erosion
100
Definition of composition and what can composition tell about where/ how rock was formed
The minerals or grains present in a rock help geologists classify the rocks composition (makeup) This information can be used to:Figure out where the rock formed and The conditions that existed when the rock formed Was it formed inside the earth from magma, on the earth’s surface when the pieces were put together, or was it formed inside the earth because of extreme temperature and pressure
100
Metamorphic classification
Foliated rocks
Foliated rocks contain parallel layers of flat and elongated minerals.
Nonfoliated
Metamorphic rocks that have mineral grains with random, interlocking textureare nonfoliated rocks
200
magma is
molten material inside earth
200
Foliated rocks
Foliated rocks contain parallel layers of flat and elongated minerals.
200
Clastic sedimentary
Clastic isrocks that are made up of broken pieces of mineral and rock fragments
200
Definition of a rock
A rock is a natural, solid mixture of minerals or grains (fragments that make up a rock)
200
4 forces that cause weathing / erosion
are wind, ice (pot holes), water, and gravity
300
lava is
molten material on earth’s surface
300
nonfoliated
Metamorphic rocks that have mineral grains with random, interlocking textureare nonfoliated rocks
300
Chemical rocks
Chemical rocks from when minerals crystallize directly from water
300
Definition of texture
texture is The size of the grains and the way they fit together
300
3 major rocks
Igneous rocks
Sedimentary rocks
Metamorphic rocks
400
Intrusive rocks are
Intrusive rocks are magma that cools slowly inside earths surface
400
How they are formed
They are formed when rocks are exposed to extreme temperatures and pressure
400
Biochemical rock
Biochemical rock is a sedimentary rock that was formed by organisms or contains the remains of organisms
400
5 steps of sedimetary
rocks uplift and then get weathered / eroded into sediment and then that sediment gets compacted into sedimentary rock
400
Fragments that make up a rock
grains
500
Extrusive rock
Extrusive rock is lava that cools quikly on earths surface
500
What is the forth type of rock extra credit on test maybe
the ROCK

Definition of grains
grains are small crushed up pieces of rocks
500
Rocks that form when sediment is deposited, compacted, and cemented and are often found in mountain valleys, along river banks, or on the beach
sedimentary rock
