Transcript of THE ROCK CYCLE

SEDIMENTARY ROCK
A couple of hundreds of years have passed and the rocks have glued themselves together
They've become layers and layers of small parts of all types of rocks
Others, due to the water, have eroded away
EXAMPLES:
BRECCIA
CHERT
DOLOMITE
ROCK SALT
THE ROCK
CYCLE

Ahh!! A volcano erupted!
After enough time magma stored up beneath the earth's lithosphere builds up and comes out through volcanoes.
Once outside the magma cools off and transforms into
IGNEOUS ROCK
BASALT
PUMICE
GRANITE
OBSIDIAN
Metamorphic
Rock
After going to ages and ages of heat and perssure, the sedimentary rock turns into metamprphic rock
IGNEOUS ROCK
Metamorphic Rock
After going through heat and pressure under the surface of the earth, the sedimentary rock turns into metamorphic rock
After going through heat and pressure under the earth's surface, the sedimentary or igneous rock can turn into metamorphic rock.
Examples:
METAMORPHIC ROCK!!!!!
Sediment
When any rock (sedimentary, igneous or metamorphic) goes through weathering and erosion, it turns into sediments.
HUMAN IMPACTS
Human pollution causes little damage to the rock cycle
However, activities such as mining & snow boarding can cause unnecessary erosion in the earth, disrupting minor parts of the cycle.
These kinds of activities can cause floods, avalanches and disrupt reservoirs
White Marble
Soapstone
Slate
Pink Marble
Magma (a.k.a reservoir)
Other things, such as car pollution, allow carbon chemicals to result in acid rain which affects the rock cycle through chemical weathering.
EXAMPLES:
Compacting & Cementing
Weathering & Erosion
Ice freezes rock and causes the rock to crack and break, therefore, the rock cycle depends on the water cycle for physical erosion.
Heat and Pressure
The heat from the tectonic plates makes the sedimentary rock metamorphic rock
After enough time, metamorphic, igneous or sedimentary rock can sink deep enough to reach the bottom of the lithosphere and turn into magma again.
AND THE ROCK CYCLE REPEATS HAPPILY EVER AFTER!
