Part 1: Identifying Rock Types
Directions: Read each description and underline or circle keywords that help determine if it is describing
igneous, sedimentary, or metamorphic rock. Next, write down your answer in the first column.
Igneous, Sedimentary, or Metamorphic
Rock
Description
These rocks are formed when existing sedimentary
rock or igneous rock are buried and exposed to
intense heat and pressure.
The rock is formed when magma or lava cools and
solidifies into rock. This rock can either be formed
above ground or underground.
This rock type can be identified by a wavy pattern
due to it being changed from intense heat and
pressure over time.
This rock is formed when sediments are deposited
at the bottom of a lake. After millions of years of
compaction and cementation this rock type is
formed.
The formation of this rock type first begins with
weathering, erosion, and deposition of sediments
into a body of water.
This rock can be identified by large crystals if
formed underground and small crystals if found
above ground.
This rock type contains fossils.
This rock type used to be a different rock type
before it was exposed to intense heat and
pressure.
You will most likely find this rock type near a
volcano.
This rock type can be identified by a wavy pattern.
This rock type can be identified by many colorful
layers.
This rock type can be identified by the presence of
crystals or air bubbles.
Part 2: Matching Practice
Directions: Read each statement and underline or circle keywords that help determine if it is describing
igneous, sedimentary, or metamorphic rock. Next, draw a line to the rock type it describes. Each rock type
has 2 matching statements.
This rock is formed when existing sedimentary rock or
igneous rock change due to intense heat and pressure.
Igneous
Rock
This rock is a result of geological processes such as
weathering, erosion, and deposition.
This rock type can be identified a wavy pattern which is
due to existing rock being changed into a new rock type.
Sedimentary
Rock
This rock consists of crystals. The crystals are larger if the
rock was formed underground and smaller if the rock was
formed above ground.
A rock formed when sediment is deposited in layers at the
bottom of a body of water. The weight of more layers
compacts and cements the layers of sediment into rock.
Metamorphic
Rock
This rock type is associated with volcanic activity.
Part 3: Vocabulary Practice
Directions: Describe each rock type in your own words. Draw a picture and include one example of each rock
type. Be sure to include key terms and characteristics of each rock type in your definition.
