The Demonstration of the Rock Cycle in Arches National
Park

Igneous To Sedimentary

The Process of igneous rocks turning to sedimentary rocks is

1 st the igneous rock goes through weathering, then erosion, and then deposition

2 nd the rock becomes sediments

3 rd compaction occurs then cementation

And then WABAM you have a
Sedimentary rock http://www.minimegeology.com/shop/images/Obsidian_W.jpg


In order for sedimentary rock to change into metamorphic rock many changes need to take place.

This requires:

High Temperatures

Great Pressure

Sometimes a chemical reaction needs to take place too.


A metamorphic rock can change into a igneous rock in 4 simple steps.

First the rock melts due to great heat and pressure.

Next the rock becomes molten rock. Also known as magma.

After that the rock cools and hardens and Ta Da! An igneous rock.

Rock Cycle Demonstrated in Arches Natl. Park

This is one of the many arches in the park.

This rock formation is sedimentary rock that has been changed by weathering and erosion.


This is a picture of the Three
Gossips.

This was formed by sedimentary rock eroding into a strange shape.

Demonstration of the
Rock Cycle in Arches

This Is the tower of Babel

It is a Metamorphic rock it was formed by heat and pressure from and igneous rock

Later it was Changed by erosion to create this shape


The Double Arch

This unique arch was formed by weathering, erosion and deposition.

It is a sedimentary rock that has been forming for over thousand of years.
