Featuring - Newfoundland The Rock Cycle Featuring - Newfoundland

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

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. Rock

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. Igneous Magma slowly quickly lava

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. sediments cemented

(rub your hands together and feel the heat). There is also heat from All rocks can be heated. But where does the heat come from? Inside Earth there is heat from (push your hands together very hard and feel the heat). There is heat from (rub your hands together and feel the heat). There is also heat from (the process that gives us nuclear power plants that make electricity). pressure friction radioactive decay

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. change metamorphic 300 to 700

The rock cycle continues 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. streams Unused word - underground
