What is Metamorphism?
The process of how Metamorphic Rocks are formed
100
How do Igneous Rocks become Sedimentary Rocks?
They are eroded into sediment and the sediment is layered and compacted into sedimentary rock
100
What are rocks from space called?
Meteorites
200
How are Intrusive Igneous Rocks formed?
When Magma cools in the Earth's crust or mantle
200
What is the first step of how Sedimentary Rocks are made?
Weathering and Erosion
200
How much heat is required to make a metamorphic rock?
300-700 degrees Celcius
200
How do Igneous Rocks become Metamorphic Rocks?
When heat and pressure is applied
200
How long does it take for rocks to change?
Millions of years
300
What type of rock is usually rough and grainy?
Intrusive Igneous Rock
300
What happens in Deposition?
The eroded material is deposited into lakes, rivers and oceans
300
How are Metamorphic Rocks formed?
When existing rocks are put under a lot of heat and pressure
300
How do Metamorphic Rocks become Igneous rocks?
The rock is melted into magma and then the magma erupts from a volcano forming Igneous rock
300
What are layers of Sedimentary Rock called?
Strata
400
What type of rock is also known as volcanic rock?
Extrusive Igneous Rock
400
What are the two steps in Sedimentation?
Compaction and Cementation
400
Why are Metamorphic Rocks different shapes and sizes?
The rock can be shaped by the direction of the heat and pressure
400
How do Metamorphic Rocks become Sedimentary Rocks?
When Metamorphic Rocks are eroded and the sediment in pressed into Sedimentary Rocks
400
Where does the word Igneous come from and what does it mean?
It comes from the Latin term "Ignis" and it means "of fire"
500
What is one example of Extrusive Igneous Rock?
-Basalt
-Obsidian
-Pumice

Describe how Sedimentary Rocks are formed?
Sediment is eroded from rocks and deposited in layers into lakes rivers or oceans. The top layers apply pressure on the bottom layers and the rock is compacted together. More heat and pressure is applied and it is cemented.
500
Why do some Metamorphic Rocks have fluids in them?
When the rock is first made the fluids can get trapped inside
