INDEPENDENT PRACTICE: Follow the directions and complete the boxes below.
Directions: Write “I” if the statement describes an igneous rock, “M” if the statement describes a metamorphic rock, and “S” if the statement
describes a sedimentary rock.
__________ Found on the slopes of Mt. St. Helens
__________ Contains dinosaur fossils
__________ Found 10 kilometers beneath the Earth’s surface
__________ Name implies that the rock has been changed/transformed
__________ Starts off as a liquid
__________ Heat and pressure can turn the other two types into this
__________ Bits and pieces of the other two types can be found in this

Formed from compacted sediment
Involves preexisting rock
Includes erosion and deposition
The cooling of lava creates this rock
Forms when extreme temperatures and pressure changes rock
Can be categorized as extrusive or intrusive
Produces layering
A change in appearance, structure, and composition might happen when creating this rock.
Finding this rock would be evidence of a volcano.

Three Major Rock Types
1.
rocks form when magma or lava cools and crystallizes.
a. Molten or liquid rock material below Earth’s surface is
called
.
b. When molten rock erupts on Earth’s surface, it is
called
.
2. Sedimentary rocks form where
is deposited.
a. Forces such as wind, running water, ice, and
cause
rocks to break down.
b. Sediment is rock material that forms where rocks are broken down into smaller
pieces or
in water as rocks erode.
c. Sediment can be
to new environments where they
are deposited and form sedimentary rock.
3. When rocks are exposed to extreme temperatures and pressure or the addition
of chemical fluids,
rocks result.
a. The minerals that make up the rock’s composition can change as well as
the
, or arrangement of the individual mineral grains.
b. In many cases, the change is so intense that the arrangement of the grains
appears as bent or
layers.
c. Metamorphic rocks form from igneous, sedimentary, or other
rocks.
4. The series of processes that change one type of rock into another type
of rock is called the
