Geologists classify rocks into 3 major groups
What is igneous, sedimentary, and metamorphic
Igneous rock that formed from magma and cooled very slowly UNDERNEATH the earth's surface is called ________.
What is intrusive rock
These small pieces or particles make up sedimentary rock. They can be parts of other rocks, plants, and animal.
What is sediment
This is how metamorphic rocks are created.
What is extreme heat and pressure
Magma cools and crystallizes in the cycle forming _______ rock
What is igneous rock
Molten rock above the surface.
Lava
The building blocks of rocks?
What are minerals?
The type of rock that forms from magma or lava cooling
What is igneous rock
This type of rock is formed from lava ON the earth's surface.
What is extrusive rock
A sedimentary rock that comes out of a solution.
What is a chemical sedimentary rock?
These types of rocks can become metamorphic rocks
What is igneous, sedimentary and other metamorphic rocks. All rocks can become metamorphic rocks.
Transporting sediments by wind, water, gravity, or glaciers.
What is erosion
This sedimentary rocks bubbles with HCl acid and can be organic or chemically formed.
What is limestone?
How does metamorphic rock form?
Heat and Pressure
The 3 types of rocks are classified this way.
What is the way rocks are formed?
An extrusive rock with dark color, fine grains and low silica

What is Basalt?
A sedimentary rock made of once-living plants and animals.
What is an organic sedimentary rock?
A term that describes a metamorphic rock with banded layers or mineral alignment.
What is foliated?
The layers of sediment become pressed together over time
What is compaction
Why do intrusive igneous rocks have large crystals?
They cool slowly.
What type of igneous rock can have air pockets or holes in it?
Extrusive
The meaning of the word "ignis" in 'igneous' rock.
What is "fire"?
This type of igneous rock is black with a glassy texture. ![]()
What is obsidan
Sedimentary rock that is formed by the accumulation of dead plant matter or animal remains being cemented together.
![]()
What are organic sedimentary rock?
The texture of a metamorphic rock that does NOT show banded or mineral alignment layers.
What is non-foliated
Rock Cycle
True or False: The Rock Cycle takes a short amount of time.
False
Molten rock below the surface.
What is magma?
Igneous rock cools very quickly. What would be the texture of an igneous rock that cools quickly?
Glassy or Fine Grained. Teacher's Discretion.
This extrusive igneous rock can float in water, and some people use it to clean their feet. It has many air bubbles.
What is pumice
The process that breaks rocks down into sediments.
What is weathering?
What does metamorphic mean?
HINT- "It's morphing time!"
What is "to change form"?
The processes by which sediments become sedimentary rocks
compaction or cementation
What is the difference between an intrusive igneous rock and an extrusive igneous rock?
Intrusive forms from magma below the surface and extrusive forms from lava above the surface.
An intrusive igneous rock with large crystals and is the main type of rock found in Earth's continental crust.
What is granite?
