Igneous Rock
Metamorphic Rocks
100
A solid collection of minerals that grow or become cemented together.Made up of one or more minerals.
What is a rock
100
These are 3 types of sedimentary rocks
What are Clastic, Chemical, and Organic
100
Describes substances that have hardened or crystallized in the spaces between loose sediments.
What is cemented.
100
This creates the color of the rock, which contains different minerals.
What is composition
100
This process starts off with some kind of rock. Heat and/or pressure then change the rock. There are two main types of this process: regional and contact.
What is metamorphism?
200
A naturally occurring, non-living
element or combination of elements.
Have unique orderly structures
(crystals), and specific characteristics
(colors, smells, size, strength).
What is a mineral
200
Explain what this process is called and its process.
Creating clastic rocks
Lithification
sediments are compacted; they are squeezed together by the weight of sediments on top of them.
sediments are cemented together; minerals fill in the spaces between the loose sediment particles. These cementing minerals come from the water that moves through the sediments
200
The process of creating rocks from sediment
What is lithification
200
These igneous rocks contain less silica.
and are dense and dark in color
What are Mafic rocks
200
Occurs over a large area.
Huge amounts of rock are exposed to high pressure from rock and sediment layers on top of it.
May also be compressed by other geological processes like tectonic plate motions.
May also experience high temperatures.
What is regional metamorphism?
300
Geologists classify rocks according to the way they are formed including
What are
igneous
sedimentary
Metamorphic rocks.
300
How would you classify Rock fragments that are compacted and cemented together
Made of sediments
sediments: particles of rock or minerals ranging in size from clay to giant boulders
What is Clastic Sedimentary Rocks
300
Rocks that are formed when when mineral crystals are formed from a liquid
What are
Chemical Sedimentary Rocks
300
These igneous rocks contain more silica.
Felsic rocks are less dense and light in color.
What are felsic rocks.
300
Occurs when magma contacts a rock.
the rock does not get hot enough to melt
the magma's extreme heat changes the rock.
What is Contact Metamorphism?
400
This will form when sediments are compacted and cemented together.
What is a sedimentary rock.
400
As liquid that is filled with minerals evaporates, it leaves behind a solid called
What is a precipitate.
400
Formed from the build-up and lithification of organic debris, such as leaves, roots, and other plant or animal material.
What are
Organic Sedimentary Rocks
400
These igneous rocks cool underground.
Deep in the crust, magma cools slowly.
Slow cooling gives crystals a chance to grow.
These rocks have relatively large crystals that are easy to see.
Give an example.
Intrusive igneous rocks. Granite.
400
Banded layers found in metamorphic rock are known as ____________.
foliation
500
Describes sediments that have hardened by being squeezed together by the weight of layers on top of them.
What is compacted.
500
Lithification is used in which two Sedimentary rock types?
Clastic and Organic
500
Forms when magma cools and forms crystals.
Two things determine looks: The composition of the magma and the rate of the magma cooling determine the rock’s texture or size of the mineral crystals
Igneous Rocks
500
These rocks form above the surface.
The lava cools quickly as it pours out onto the surface
Extrusive rocks cool much quicker than intrusive rocks.
Rapid cooling time does not allow time for large crystals to form.
- They have smaller crystals than intrusive rocks.
They are also called volcanic rocks.
Give an example
Extrusive igneous rocks 
500
During metamorphism, ____________ move between minerals.
ions
