What must happen to rocks at the surface to create sediments?
What is: undergo weathering and erosion.
100
Which igneous rock makes up the oceans?

This term is used to describe those rocks formed inside the earth.
What is Intrusive
200
What process is responsible for "gluing" sediments together?
What is Cementation.
200
As you dig deeper into the earth, what two properties increase?
What is: Temperature and Pressure
200
Partial melting will create this type of rock.
What is: Metamorphic rock
200
Which sedimentary rock will bubble and fizz when HCL acid is dropped on it?
What is: Limestone
300
This type of magma creates rocks that are dark colored ; very dense and composed of iron and magnesium.
What is Mafic Magma.
300
Identify the 3 categories of sedimentary rock.
What is: Clastic, Organic and Chemical
300
Thisterm describes the texture of a rock with wavy bands.
What is: Foliated
300
Crystallization and solidification are words to describe the formation of which type of rocks?
What is: Igneous rocks
300
Name 3 igneous rocks that show a "glassy" texture. (Hint: Remember your lab!)
What is: Obsidian, Scoria and Pumice
400
Identify the 2 types of textures associated with extrusive rocks.
What is Fine-grained and Glassy.
400
You find a rock that contains large and small rounded pebbles. What is it's name and what type of sedimentary rock is it?
What is: Conglomerate and Clastic
400
Identify the Parent rock for each of the following:
Gneiss
Schist
Marble
What is:
Granite changes into Gneiss
Shale changes into Schist
Limestone changes into Marble
400
Explain how a sedimentary rock can change into an igneous rock.
What is: sedimentary rock must be forced back into the earth and increase in temperature to the point will the rock melts and create magma from which a new igneous rock will form.
400
This metamorphic rock can be created when either shale or slate undergoes metamorphism.
What is: Schist
500
Give the texture and composition for granite.
What is Coarse-grained and Felsic
500
Identify the category each rock would fit into:
Coal
Halite
Shale
What is:
Coal = Organics
Halite = Chemical
Shale = Clastic
500
Metamorphism that occurs on a smaller scale due to volcanic eruptions and magma chambers is termed?
What is: Contact Metamorphism
500
Explain how a sedimentary rock becomes a metamorphic rock.
What is: a sedimentary rock must undergo mountain building or come in contact with magma. It wil heat up and partial melt. When it cools, the minerals will be interlocking.
500
Identify and describe the 2 textures used for metamorphic rocks.
What is:
Foliated - alternating light and dark bands; may be wavy.
Non-foliated - no banding found in rock.
