IGNEOUS
cool slowly, have coarse (big) mineral grains, formed from magma
INTRUSIVE igneous rocks
Rocks that experience change caused by pressure deep below or collision with other rock formation
metamorphic rocks
the breaking down of rock into smaller pieces called sediment
weathering
This type of rock makes up 75% of the rocks on Earth.
SEDIMENTARY
molten or hot, liquid rock, found under Earth’s surface
magma
molten or hot, liquid rock, found on top of Earth’s surface
lava
The two types of Metamorphic rocks are
CONTACT & REGIONAL
a type of sedimentary rock that contains pieces of rock that are stuck together
CLASTIC sedimentary rocks
A piece of GRANITE falls down a cliff and is broken into several pieces, it is then swept away by a river....
WHAT TYPE OF ROCK WILL THIS EVENTUALLY TURN INTO?
Sedimentary
forms when magma “intrudes” or pushes into surrounding rock, under Earth’s surface
intrusive igneous rock
Obsidian, Pumice, and Bassalt are examples of
The process in which mineral grains are flat and aligned in planes or bands
foliated
a type of sedimentary rock that contains living things or the remains of living things
ORGANIC sedimentary rocks
A piece of pumice is swept away in a pool of LAVA. What rock will it most likely turn back into?
IGNEOUS
Cool quickly, have fine (small) mineral grains, formed from lava
extrusive igneous rocks
3 Geological Processes that create Igneous Rock
Melting, Cooling, Crystallizing
The process in which mineral grains may change in size or composition
Non-Foliated
sandstone; conglomerate; breccia; and shale are all examples of what type of sedimentary rock?
CLASTIC
70% Pressure and 30% Heat would create what type of Rock? BE SPECIFIC.
A REGIONAL METAMORPHIC ROCK
the process in which sedimentary rocks are arranged in layers
stratification
Granite and Diorite are examples of
INTRUSIVE igneous rocks
Gneiss is an example of which type of metamorphic rock?
Regional
Halite (sodium chloride aka salt) AND limestone (calcium carbonate) are examples of what type of sedimentary rock?
CHEMICAL sedimentary rock
A large rainstorm with high winds causes a large build- up on the ground near a riverbank. What process is occurring? AND What rock can it turn into?
Deposition
Sedimentary
The pressing of layers of sediment together
compaction
