Metamorphic Rock
Metamorphic rocks form
deep within the Earth when
heat and pressure are
applied to either igneous
rocks or sedimentary rocks.
This heat and pressure in
essence cooks the rocks,
changing their structure
substantially.
Wednesday, April 29, 15
Fun facts
 Marble and slate are examples of
metamorphic rock.
 Metamorphic rock is formed under
extreme pressure combined with
heat over time.
 Metamorphic rocks are so called
because they always begin as another
type of rock.

Igneous Rock
 All rocks on Earth were
initially igneous in
nature. Igneous rocks
form as liquid magma
cools, forming crystal
structured rocks. There
are many different types
of igneous rocks.
Wednesday, April 29, 15
Fun Facts
 There are over 700 different types of
igneous rocks.
 The upper section of the Earth's crust is
made up of around 95% igneous rock.
 Granite is a common rock that contains at
least 25% quartz and is sometimes used in
construction because of its strength.

Sedimentary Rock
 Sedimentary rocks are
formed by sediment that
is deposited over time,
usually as layers at the
bottom of lakes and
oceans.
Wednesday, April 29, 15
Fun Facts
 This sediment can include minerals, small
pieces of plants and other organic matter.
 Sedimentary rocks cover the majority of the
Earth's rocky surface but only make up a
small percentage of the Earth’s crust
compared to metamorphic and igneous
types of rocks.
