Igneous
This is molten rock found below the earth's surface.
Magma
tiny pieces of rock, sand, shells, etc. is called what
metamorphic rocks can be made from ____________, _______________, or _______________________ rocks.
Sedimentary, metamorphic and igneous.
When sediments go under compacting and cementing processes they become___________
What is sedimentary rocks.
There are _____________tectonic plates
14
The theory that all rocks are just broken down and made into new rocks is known as what cycle.
The rock cycle
This is molten rock found above the earth's surface.
Lava
The final 2 processes that turn sediments into sedimentary rocks?
Compaction and cementation
Propose a reason why the lines/layers of metamorphic rock are wavy compared to sedimentary rock having straight lines/layers.
Metamorphic rocks have wavy layers due to heat.
When igneous, metamorphic and sedimentary rocks go under weathering and eroding they become_________________
What is sediments?
What is the inner layer of the Earth?
Core
What type of rock is basalt?
Extrusive igneous
Igneous rocks are categorized as _________ or _________, depending on where the molten rock cooled.
Extrusive and intrusive.
What is the difference between weathering, erosion and deposition?
Weathering breaks rock down.
Erosion carries it away.
Deposition drops the sediment off.
It may take ____ of years for sedimentary rocks to form
Millions
The processes that turn metamorphic rocks into sediments
What are weathering and eroding?
A resin fossil is when living things get trapped in
tree sap
The oldest rocks on earth are found in which layers
What are the bottom ones?
__________ igneous rocks have larger crystals than the other kind of igneous rocks.
Intrusive?
This type of sedimentary rocks form when dead plants from millions of years ago mineralizes. We use it to heat homes
Coal
What are the two processes that create sediments from sedimentary rock?
Weathering and erosion
_________ and ____________ turn sedimentary rocks into metamorphic rocks.
Heat and pressure
A youngest rocks are laid on the ________
The top
The study of rocks, their history and the processes that form and change them.
What is geology?
Why do some extrusive igneous rocks have no crystals?
Give three examples of how erosion can occur.
Wind, water or ice.
Animals, vehicles etc..
Shale is the parent rock of this metamorphic rock.
What is slate?
When metamorphic and igneous rocks go under melting they turn into__________
Magma?
What are the layers of the earth in order from the inner to outer layer
Core, mantle, crust
What are the steps in the formation of sedimentary rock
1.Weathering (breaking) of rocks to sediments
2. Erosion (moving) of sediments to sedimentary environments
3.Compaction (squeezing) and cementation (gluing)
