The Rock cycle
Weathering
100
This is the type of rock that forms when hot magma cools and hardens.
What is Igneous Rock?
100
These rocks form as lava cools on the surface of the Earth.
What are extrusive igneous rocks?
100
This process breaks rocks into smaller pieces.
What is weathering?
100
Using the rock cycle diagram, these two processes form Igneous rock.
What is melting and solidification?
100
This forms when pieces of dead plants are buried under other sediments in swamps and are compacted. (You do NOT want this fossil fuel for Christmas)
What is coal?
200
These rocks are formed when heat and pressure alter other types of rocks.
What is Metamorphic Rock?
200
If the magma takes a long time to cool this will be true about the rock that forms.
What is it will have large crystals in it?
200
Matter can neither be created nor destroyed!!!
What is the law of conservation of matter?
200
Using the rock cycle diagram, these two processes form sediments.
What are weathering and erosion?
200
This model shows that rocks change continually from one form to another
What is the rock cycle?
300
These rocks are formed when sediments are pressed and cemented together.
What are Sedimentary Rocks?
300
When mineral grains line up in parallel layers the metamorphic rock will have this.
What is a foliated texture?
300
This is the movement of particles by the action of wind, water, gravity, or glaciers.
What is erosion?
300
Using the rock cycle diagram, these two processes form Metamorphic Rock.
What are heat and pressure or metamorphism?
300
When rock fragments are picked up and carried by a water source this happens to the size and shape of the particle.
What is is gets smaller and becomes rounded off (eroded)?
400
All rocks are composed of these?
What are minerals?
400
This is a mixture of minerals, rock fragments, volcanic glass, organic matter, or other natural materials.
What is a rock?
400
Using the rock cycle diagram, these four processes form Sedimentary Rock.
What are deposition, burial, compaction and cementation?
400
When water freezes this happens.
What is it expands and forms ice?
500
This type of rock would have a fossil imprint of a footprint in it.
What is a sedimentary rock?
500
These are two of the three groups of sedimentary rocks.
What are any two of the following: detrital, chemical and organic sedimentary rocks?
500
This is the name given to igneous rocks that form below the surface of the Earth.
What is intrusive?
500
Using the rock cycle diagram, before an igneous rock forms it must be this first.
What is magma or lava?
500
This type of metamorphic rock does not have any layers.
What is nonfoliated metamorphic rock?
