Objective 12/5/12
Describe how each type of rock changes into another type as it moves
through the rock cycle.
Intro
What are rocks made of?
Do you know the name of
any rocks?
How are they formed?
ROCK CYCLE
Rock Cycle

rock

A naturally occurring
solid mixture of one or
more minerals, rock
particles or organic
matter
Rock Cycle

How are rocks
classified?




Based on how they are
formed
Some originate in magma
Others from sediments
Others are squished and
heated.
Rock Cycle

Three Types of Rocks




Igneous
Sedimentary
Metamorphic
Texture can help
determine the type of
rock
Rock Cycle

Rock Cycle

The continual process by
which new rock forms
from old rock material.
Rock Cycle

Igneous Rocks


Sedimentary Rock


Form when molten rock
cools
Rocks that weather
and erode are called
sediments
When sediments are
compacted they create
sedimentary rock
Rock Cycle

Weathering


Sediments


Erosion


Compaction

Breaking down of rocks
into tiny pieces
Tiny pieces of rock
Process of transporting
sediments
Process of sediments
becoming squished
together to form a rock
Rock Cycle

Metamorphic Rock

Forms when rocks are
put under enormous
heat & pressure
Objective 12/5/12
Describe how each type of rock changes into another type as it moves
through the rock cycle.
Outro
How do rocks change from
one type of rock into
another?
