Rocks Review Game

A naturally occurring, solid mixture of one or ore minerals and organic matter

Rocks

How did humans use rocks in the past?

Tools, weapons, and building materials

What is the process in which water, wind, and heat break down rock?

Weathering/erosion

If magma cools quickly, what kind of texture will the rock have?

Fine-grained

What are 3 ways that magma forms?

Increase temperaturedecrease pressure

change composition

What has to increase for metamorphism to occur?

Heat and pressure

The process of forming a sedimentary rock when minerals dissolve then bond the

sediments together (like glue)

cementation

Layers of sedimentary rock are called

strata

What are the 3 types of sedimentary rock

Clastic, chemical, and organic

What type of rock forms when magma cools?

igneous

What determines the size of the crystals in an igneous rock?

How fast or slow the magma/lava cools

Type of igneous rock that forms when magma cools below the Earth’s surface

intrusive

Metamorphic rock in which the mineral grains are arranged in planes or bands

foliated

What are the two ways rocks are classified?

Texture and Composition

What does Composition mean?

What a rock is made up of

Light – colored igneous rocks are called

felsic

Felsic igneous rocks are made up of mostly

quartz

Dark-colored igneous rocks are called

mafic

Mafic igneous rocks are made up of mostly

Plant materials

Process in which sediment is dropped and comes to rest

deposition

Process by which new rock is made from old rock

Rock Cycle

The quality of a rock based on the size and shape of the mineral grains

texture

Minerals used to estimate the temperature and depth that a rock undergoes metamorphism

Index minerals

Metamorphic rock in which mineral grains are NOT arranged in bands

nonfoliated

Process in which layers in sedimentary rock are formed

stratification

Metamorphic rock formed in large areas deep under the Earth’s surface

Regional metamorphism

Metamorphic rock formed in small areas due to rising magma

Contact metamorphism

Igneous rock that cools below the Earth’s surface

intrusive
