What is sediment?
Small pieces of broken down rock, sand, or gravel.

What are the 2 textures of metamorphic rock?
Foliated and nonfoliated

The process by which sediment is dropped and comes to rest
deposition
100
A solid mixture of one or more minerals and organic matter

Where are you likely to find igneous rocks?
Near volcanoes
200
What are strata?
layers in sedimentary rock
200
What is contact metamorphism?
When rock is heated up near magma inside the earth
200
During the rock cycle, what forms when magma cools?
igneous rock
200
The process by which new rock forms from old rock
Rock Cycle

What kind of texture does igneous rock have when magma cools quickly?
fine-grained
300
Name the three types of sedimentary rock
Clastic, Chemical, Organic

What is regional metamorphism?
When pressure of rocks deep inside the Earth deform layers of rock.
300
When sedimentary rock is exposed to heat and pressure what does it turn into?
metamorphic rock
300
The size, shape, and position of grains that make up a rock
Texture
400
What kind of texture does igneous rock have when the magma cools slowly?
coarse-grained
400
What is the process called in which sedimentary rock is arranged in layers?
Stratification
400
How does the rate at which magma cools affect its texture?
If the magma cools slowly it will have coarse-grained texture, if the magma cools quickly it will have fine grained texture.
400
The process by which sediment is removed from its source
erosion

What kind of sedimentary rock is made from fossils?
Organic Sedimentary Rock

You are walking on land where a volcano was once active. You pick up a rock that is smooth and appears to have no crystals. How do you think this rock was formed?
A volcano erupted and the magma cooled quickly giving the rock a fine-grained texture.
