Group Activity: Is it a rock?
Write down the names of the following
items that you believe are rocks:
Cement block
Dried mud
Hardened lava
Asphalt (road tar)
Glass
Piece of clay pot
Coral
Limestone
Iron ore
Concrete
Coal
brick
A gravestone
Marble statue
granite
Explain your thinking. What “rule” or
reasoning did you use to decide if
something is a rock?
The Rock Cycle
You know that paper, plastic, and
aluminum can be recycled. But did you
know that the Earth also recycles? And one
of the things that Earth recycles is rock.
Discuss the following questions with your
group:
 What is rock?
 How can rock be recycled?
 How long would recycling a rock take?
 What would the rock look like before, during,
and after the process of recycling?
The Rock Cycle
rock
Scientist define ________
as a
naturally occurring solid mixture
of one or more minerals and
organic matter.
ROCKS ARE ALWAYS CHANGING!
The continual process by which
new rocks forms from old rock
rock
material is called the _______
cycle
________.
The Value of Rock
 Rock has been an important natural
resource as long as humans have
existed.
 Discuss the following questions with
your group:
 How did early humans use rock?
 What are some other ways rock has been
used throughout the centuries?
 Let’s look at page 360.
Processes that Shape the Earth
 Let’s look at the top of pg. 361
 The process in which water, wind,
ice, and heat break down rock is
called ___________.
weathering
 Discuss with your group why this is
important.
 Weathering is important because it
breaks down rock into fragments
sediment
called __________.
These
sedimentary
sediments make _____________
rock
______.
Processes that Shape the Earth
 The process by which the sediment is
removed from its source and carried
erosion
away is called ________.
Causes of
erosion:
 Water
 Wind
 Ice
 Gravity
 The process in which sediment moved
by erosion is dropped and comes to
deposition
rest is called ____________.
 Let’s look at pg. 361
Each group member choose either the
rock cycle, weathering, erosion, or
deposition to teach to your group. Take
turns and use the SLANT method to
listen! You have 2 minutes!
Processes that Shape the Earth
 How the cycle continues…
 Sediment may be pressed or
compacted and cemented together
under the pressure of layers to form
sedimentary rock.
 Buried rock is exposed at the Earth’s
surface by a combination of _______
uplift
erosion
and _______.
movement
 Uplift is ___________
within the
rocks
Earth that causes _______
inside the
Earth to be moved to the Earth’s
surface.
Heat & Pressure



If the temperature and pressure
are high enough at the bottom of
the sediment, the sedimentary
rock can change into a
rock
metamorphic ______.
___________
In some cases, the rock gets
hot enough to melt into
magma
_________.
The magma eventually cools to
igneous
rock
form __________
______.
Rock Classification
Scientist classify rocks by composition and
texture.
The minerals a rock contains determine the
composition of that rock.
___________
Look on page 365.
The size, shape, and positions of the grains
that make up a rock determines a rock’s
___________.
texture
Look on page 366.
The Rock Cycle
Pg. 364
compaction &
cementation
solidification
Exit Ticket
On an index card, choose one of the
three types of rock and write a
description of how the rock is
formed.
