Rocks
What is deposition?"
The process by which sediment comes to rest.
What is the rock cycle?
The processes in which rock changes from one type of rock to another
Where does Igneous rock form?
Below the ground
Weathering does what to rocks?
Breaks them down.
Planes or bands are found in....
Foliated metamorphic rock
Composition is...
the chemical makeup of a rock; describes either the minerals or other material in the rock
Metamorphic rocks that are nonfoliated...
Have mineral grains that are NOT arranged in planes or bands
What takes place when an igneous rock turns into a sedimentary rock?
Temperature decreases
Rocks break down over time due to their exposure to wind, water and ice. What is this an example of?
Weathering
Name two types of igneous rock.

True
Rocks can change into other types of rocks
True
What kind of rock is formed from lava that cools on Earth’s surface?
Extrusive Igneous rock
What kind of sedimentary rock is formed when sediments are buried, compacted, and cemented together by calcite or quartz.
Clastic sedimentary rock
What is a rock that is formed when magma cools below the Earth’s surface?
Intrusive Igneous rock
The process by which sediment settles ( or comes to rest) out of the water or the wind carrying it is called...
Deposition
What is weathering?
Water, ice, wind and changes in temperature break down rock
Rocks can be classified according to their (give 2)
composition and texture
What kind of metamorphic rock has its mineral grains arranged in planes or bands?
Foilated Igneous rock
What is erosion?
The process by which sediment is moved from one place to another
What are the three ways minerals form?
Metamorphism( heat and pressure), Solutions
( Minerals dissolve in water) ,Magma and lava cool
( heating and cooling)
INTRUSIVE IGNEOUS ROCK has what texture and what type crystals?
This rock generally has a coarse-grained texture and large crystals.
Which type of rock is formed when magma cools underground inside the Earth's surface?
Intrusive Igneous Rock
What does WED stand for?
Weathering -> break it down
Erosion -> move it
Deposition -> drop it
Where do organic sedimentary rock come from?
Sedimentary rock forms from the remains or fossils of once- living plants and animals
