What is the relationship between metamorphism with a rock and popcorn?
100
Many of the metamorphic rocks people use were once sedimentary rocks. These rocks changed over time.
Do rocks change?
100
Metamorphism is the process in which an existing rock is changed by heat or pressure.

Igneous rocks form as molten rock cools. Extrusive is formed from lava, and intrusive is formed from magma.
How do Igneous rocks form?

Shale is a sedimentary rock that forms near the surface. It can be buried deeper as the blocks of the crust push together. Shale then changes into SLATE as pressure causes the minerals to line up in layers. Mica starts to grow as crystallization begins.
How does SHALE turn into SLATE?
200
Yes, An example of shale can turn into schist. (This happens through density and deepness of increasing pressure and temperature the lower the rock gets.)
Can shale turn into schist?
200
Through heat and pressure.
How do rocks change?

The atomic bands break, and can rejoin together different as new bonds form.
What is crystallization?

Sedimentary rocks form from earlier rocks.
How do Sedimentary rocks form?

Yes, Schist can turn into Phyllite. If the pressure and temperature decreases, and it forces it's way UPWARD- then it will turn into Phyllite.
Can Schist turn into Phyllite?

Forces within Earth start to press rock layers together over hundreds of kilometers. Heat and pressure change the rock layers that make up the mountains into metamorphic rock.
Changes over LARGE AREAS?
300
The plates and layers of the Earth cause the rocks to move.
What causes them to move?
300
A rock that is the original, it can change into different rocks. If a rock starts out as SHALE, it can then go into metamorphosis and come out a Gneiss the deeper it goes.
What is a parent rock?
300
Gravel, sand, silt and clay. (In order) *hint hint!*
What is the order in which Sediments settle?
300
It depends on where the rock is. It could go through either heat, pressure, or both.
Can rocks change through JUST heat or JUST pressure?
400
Magma can push into rock layers and cause changes over areas ranging from a few centimeters to tens of meters. The magma is hot enough to bake the surrounding rock into metamorphic rocks.
Changes over SMALL AREAS?
400
LARGE AREAS: Forces within Earth start to press rock layers together over hundreds of kilometers. Heat and pressure change the rock layers that make up the mountains into metamorphic rock. SMALL AREAS: Magma can push into rock layers and cause changes over areas ranging from a few cms to tens of meters. The magma is hot enough to bake the surrounding rocks into metamorphic rocks.
What type of changes occur to LARGE & SMALL areas?

Limestone is the parent rock of Marble.

As plants died, their remains fell upon the remains of earlier plants. Then layers of other sediments buried the layers of plant remains. The weight of the sediments above pressed the plant material into coal.
How is coal formed?

(REVIEW!) Yes Sedimentary and Igneous rocks can be counted as Metamorphic because they can change.
Can Sedimentary and Igneous rocks be counted as Metamorphic?
500
Shale, Slate, Phyllite, Schist, and Gneiss. It can start off with shale, and end with Gneiss.
What is the order of which the rocks change in depth starting with Shale and ending with Gneiss?
500
Shale, Slate, Phyllite, Schist, Gneiss, are some examples of metamorphic rocks.
What are some examples of metamorphic rocks?
500
(Yo! This is from 3.3! Have fun!) Materials that settle out of water or air.
What are Sediments?
500
Processes similar to the ones that produce sedimentary rocks from rock particles also produce rocks from shells or plant remains. These remains are fossils. A fossil is the remains or trace of an organism from long ago.
Is there another way rocks form?
500
Igneous forms either through magma or lava. Sedimentary forms through wind and air. Metamorphic forms through heat and pressure.
How does Igneous, Sedimentary, and Metamorphic rock form?
