Unit 2:
Section 1: Types of rock
Section 2: Rock Cycle
Section 3: Weathering
Section 4: Erosion
There are 3
different
types of
rocks.
Rocks are
classified
based on
the way that
they form.
6
Rock Cycle
These three forms can be formed,
broken down and reformed in a
continuous process known as the rock
cycle.
The rock cycle begins with magma
(melted rock beneath the Earth’s
surface) or lava (magma that has
reached the surface).
When these cool, igneous rock is
formed. These rocks then can be
broken into small pieces called
sediments by processes called erosion
or weathering.
After being carried by wind and water,
they end up in piles. After many
9
These sediments are then pressed and
glued together in processes called
compaction and cementation.
Some of the sedimentary rock at
the very bottom begin to get squished
by the
pressure
from all the rock on
top of it. As they get pushed down
further, they
heat
up and begin to
bake! The rocks bake so much that
they became new rock called
Some of the rock get so hot that it
even melts back into magma and
traveled back to the mantle.

Is there anything you could have
done differently to have done
better?

Going forward, what actions will
you take to be successful in this
class?

The energy to melt rocks comes from
heat in the Earth’s core.
Are made from cooled-down lava
Don’t have layers.
They may contain crystals or have a glassy appearance.
Granite is a common, igneous rock It is formed inside
the Earth so it is called an intrusive igneous rock.
Rhyolite and obsidian have small or no crystals and are
formed at the surface by lava so they are called
extrusive igneous rocks.
Hints that you are seeing an igneous rock:
Bubbles
Glassy appearance
Metamorphic rocks are made when a rock
changes due to heat or pressure.
May have fine layers or no layers at all.
They are usually very dense, hard rocks.
Marble and diamond are metamorphic
rocks.
Hints that you are seeing a metamorphic
rock:
Sedimentary rocks are made of sediments
(particles) that build up in layers, usually at
the bottom of a river or lake.
Sandstone and limestone are sedimentary.
The places they formed usually had water in
some form such as rivers, lakes or oceans.
These are the only rocks to contain fossils.
Hints that you are seeing a sedimentary rock:
Flat layers

Sedimentary (mix of particle size)

cementation- natural bonding process caused by water moving thru rock and soil deposition- also known as sedimentation, is the geological process by which
wind, water, or ice create a sediment deposit by laying down of material that has been eroded and transported
