What are the basic processes required to make a metamorphic rock?
Heat and pressure.

What is the inner most layer of the Earth?
The inner core
200
What are are two clues to help us figure out origin?
Texture and mineral composition (or color)
200
Name the three types of sedimentary rocks
Clastic, organic, chemical
200
Name one use for a metamorphic rock
Building, or sculpture
200
Sandstone
A clastic sedimentary rock formed from sand particles
200
Where do we find convection currents?
In the mantle.
300
Describe which origin lava is involved in.
Extrusive because once magma leaves the Earth it is called lava and when rocks are formed above the Earth's surface they are extrusive.
300
List the four steps in the formation of sedimentary rocks in order.
(1) Erosion (2) Deposition (3) Compaction (4) Cementation
300
What are the two types of metamorphic rocks?
Foliated, non-foliated
300
Obsidian
Extrusive igneous rock
300
What are the three type of waves we get from Earthquakes?
P, S, and surface waves
400
What mineral is important to mineral composition and what do higher levels of it mean?
Silica. When there are high levels of silica then the rock is lighter and usually intrusive.

Describe a conglomerate
A clastic sedimentary rock that is made up of rock fragments with rounded edges.
400
What are the characteristics of a foliated rock?
Banded minerals
400
Quartizite
Non-foliated metamorphic

What is Pangea?
The original super-continent that existed 300 million years ago
500
Name an igneous rock and give its origin, texture, and color
Ms. Eisermann will approve answer!

Why do we only find fossils in sedimentary rocks?
Because they have the proper environment to preserve organic material.

Describe how and what granite turns into.
Granite, with heat and pressure, turns into a foliated metamorphic rock called gneiss
