Misc. II
100
This can cool and harden and form igneous rock.
What is magma/lava?
100
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
100
These 2 things cause metamorphic rocks to form.
What are Heat and Pressure?
100
This property describes how easily a mineral can be scratched.
What is 'hardness'?
100
This process moves sediment from one place to another.
What is erosion?
200
This kind of igneous rock is formed when magma cools beneath the Earth's surface.
What is Intrusive Igneous Rock?
200
They are the three types of rock.
What are Igneous, Sedimentary and Metamorphic?
200
These types of rocks come out of volcanoes.
What are igneous rocks?
200
This is a mineral's tendency to split along a flat surface.
What is cleavage?
200
This kind of weathering breaks down rock without changing its composition.
What is mechanical weathering?
300
These rocks are made up of the remains of plants and animals.
What are sedimentary rocks?
300
For an Igneous rock to become a sedimentary rock, what needs to happen?
What are weathering, erosion, compaction and cementation?
300
Slow cooling of magma produces rocks with this property.
What are large crystals?
300
This leaves a powder on a ceramic plate.
What is streak?
300
The Rock Cycle goes in this direction.
What is Any direction?
400
This describes how rocks turn from one type of rock into another.
What is The Rock Cycle?
400
This rock type may be weathered to become sediment, and eventually sedimentary rock.
What are All Rock Types.
400
True or False: To be a mineral, a substance cannot be living and can never have lived.
What is true?
400
If a metamorphic rock melts and then cools, it is this type of rock.
What is an igneous rock?
500
This determines the size of crystals that form in igneous rocks.
What is the Rate of Cooling?
500
These are the only type of rock which contain fossils.
What are sedimentary rocks?
500
These forces change the earth's landscape.
What are weathering and erosion?
500
True or False: Natural gas is mineral.
What is false?
500
If a sedimentary rock is buried deep in the earth and subjected to intense heat and pressure, but does not melt, it becomes this type of rock.
What is a metamorphic rock?
