Rock Formations Study Guide

The 3 types of rocks are:

• Igneous, Sedimentary, Metamorphic

• Igneous, Metamorphic, Fossil

• Sedimentary, Fossil, Igneous

• Metamorphic, Fossil, Sedimentary

Sedimentary rock forms through the process of:

• melting and cooling

• erosion, deposition, compaction, and cementation

• heat and pressure

• crystallization from magma

Metamorphic rock forms through the process of:

• melting and cooling

• erosion and sedimentation

• heat and pressure

• deposition and compaction

How does igneous rock form?

• By the cooling and solidification of magma or lava

• Through the process of erosion and sedimentation

• By the compression and cementation of sediments

• Through the transformation of existing rock types

If a rock has clear bands, what type of rock are you looking at?

• Igneous rock

• Sedimentary rock

• Metamorphic rock

• Volcanic rock

If a rock is glassy black with sharp edges what type of rock are you looking at?

• Igneous

• Granite

• Sandstone

• Limestone

If a rock has small shells and pebbles stuck together, what type of rock are you looking at?

• Igneous rock

• Sedimentary rock

• Metamorphic rock

• Volcanic rock

The process of breaking rocks into smaller pieces is called:

• Erosion

• Weathering

• Sedimentation

• Compaction

Where does the energy come from that weathers rocks?

• The Sun

• The Earth's core

• Wind

• Water

The energy that melts rocks comes from:

• the sun

• the Earth's core

• ocean currents

• wind energy
