The Rock Cycle

2. Join me on an exciting voyage of discovery of the rock cycle
using the Newfoundland landscape as a backdrop!

3. The Cycle is a group of changes
The Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock.

4. rock forms when magma cools and makes crystals
rock forms when magma cools and makes crystals is a hot liquid made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools Or, igneous rock can form above ground, where the magma cools When it arrives at the Earth's surface, magma is called This is the same liquid rock matter that you see rolling out of volcanoes.

7. On Earth's surface, wind and water can break rock into pieces
On Earth's surface, wind and water can break rock into pieces. They can also carry rock pieces to another place. Usually, the rock pieces, called
, drop from the wind or water to make a layer. The layer can be buried under other layers of sediments. After a long time the sediments can be together to make sedimentary rock. In this way, igneous rock can become sedimentary rock.

All rocks can be heated. But where does the heat come from? Inside Earth there is heat from

11. So, what does the heat do to the rock. It bakes the rock
So, what does the heat do to the rock? It bakes the rock. Baked rock does not melt, but it does It forms crystals or, if it has crystals already, it forms larger crystals. Because this rock changes, it is called A caterpillar changes to become a butterfly. That change is called metamorphosis. Metamorphosis can occur in rock when they are heated to degrees Celsius. When Earth's tectonic plates move around, they produce heat. When they collide, they build mountains and metamorphose (met-ah-MORE-foes) the rock.

The rock cycle continues. Mountains made of metamorphic rocks can be broken up and washed away by New sediments from these mountains can make new sedimentary rock.
