Transcript of Rock Cycle

Igneous
(Basalt)

Metamorphic
(Marble)

Sedimentary
(Sandstone)

The
Rock
Cycle

The Magma cools
and hardens into an
IGNEOUS
rock.
Over time, heat and pressure
build up around the rock and
causes it to melt into
MAGMA
.
A
METAMORPHIC
rock
lays deep underground.
The continued heat
and pressure cause the
to change into a
METAMORPHIC
rock.
Over time,
HEAT
and
PRESSURE
build up
around the rock.
A
SEDIMENTARY
rock
sits deep in the Earth.
Exposed
IGNEOUS
stone
erodes away from different types of
VOLCANOES
.
Igneous rocks include:
Obsidian
Pumice
Rhyolite
Andesite
Baslat
Granite
Gabbro
3 volcano types
Shield volcano
Composite volcano
Cone volcano
Different metamorphic rock types:
Slate
Phyllite
Schist
Gneiss
Marble
Quartzite
Sediments
of stone collect
at the bottom of the lake
Over time, pressure
fuses the sediments together
to form
SEDIMENTARY
rock.
Common sedimentary rocks:
Conglomerate
Breccia
Sandstone
Mudstone
Limestone
Coal
An
IGNEOUS
rock is buried
deep under the ground.
Over time,
HEAT
and
PRESSURE
build up around
the rock.
Continued heat and pressure
causes the rock to change into
a
METAMORPHIC
rock.
Exposed
METAMORPHIC
rock erodes and washes away
near oceans and lakes.
The
SEDIMENTS
of stone
lay at the bottom of the
lake or ocean.
Over time, pressure causes
the sediments to fuse into
a
SEDIMENTARY
rock.
The magma cools and forms
into an
IGNEOUS
rock.
Heat and pressure causes
the rock to melt into
MAGMA
.
SEDIMENTARY
rock buried
deep under the ground.
Basalt:
