The color of a mineral in powdered form.

What is streak?

100

The series of processes that change one type of rock into another type of rock

What is the rock cycle?

100

Molten rock that erupts at the surface

What is lava?

100

These are broken pieces of rock

What are clasts?

100

Layers that form a metamorphic rock do not form due to deposition, but do to this "pressing" factor.

What is pressure?
200

This mineral has a 1 on Moh's Hardness scale, and can be scratched by your fingernail.

What is talc?

200

The fragments that make up a rock

What are grains?

200

This common igneous rock is an intrusive rock that has visible crystals.

What is granite?

200

This sedimentary rock is easy to identify near a river bed due to the combination of several rocks in it.

What is conglomerate?

200

Any process that affects the structure or composition of a rock in a solid state as a result of changes in temperature and pressure.

What is metamorphism?

300

A property that can be described in a number of wordy ways, such as "metallic", "shiny", "dull", "pearly", or "vitreous".

What is luster?

300

The cooling and crystallization of magma leads to this kind of rock.

What is an igneous rock?
300

This type of igneous rock shows up when volcanic material erupts and cools and crystallizes on Earth’s surface

What is an extrusive rock?

300

A type of sedimentary rock that was formed by organisms or contains the remains of organisms

What is a biochemical sedimentary rock?

300

These metamorphic rocks contain parallel layers of flat and elongated minerals. An example is shown below

What is a foliated rock?
400

A naturally occurring solid material from which a metal or valuable mineral can be profitably extracted.

What is an ore?

400

Extreme temperatures and pressures lead to existing rocks becoming these new types of rocks

What is a metamorphic rock?

400

This common igneous rock on the ocean floor cooled quickly, and has small crystals.

What is basalt?

400

This is not just a sedimentary rock, but also a fossil fuel from the remains of plants.

What is coal?

400

These are metamorphic rocks that have mineral grains with a random, interlocking texture

What is marble?

500

This brown-colored mineral is a great conductor of electricity and is used for wires and plumbing.

What is copper?
500

Deposition, compaction, and cementation lead to this kind of rock

What is a sedimentary rock?

500

This glassy-like rock is also known as volcanic glass.

What is obsidian?

500

The process where weight from layers of sediment forces out fluids and decreases the space between grains.

What is compaction?

500

The formation of metamorphic rock bodies that are hundreds of square kilometers in size

What is regional metamorphism?
