The Rock Cycle
Testo Storyboard
- Igneous, Sedimentary and Metamorphic rocks like me are constantly being broken down by wind and water. Due to some factors,  I am worn down to small particles.
- HI, IM ROCKY AND IM GOING TO TAKE YOU THROUGH THE ROCK CYCLE!
- Weathering occurs when the particles are broken off a rock and stay in the same area. Erosion is when the particles are carried somewhere else, 
- Hi, I'm finally a sedimentary rock!
- Transportation happens when eroded rock particles are carried away by wind or by rain, streams, rivers, and oceans.
- Time to turn into a Metamorphic rock!
- Deposition occurs when the rivers flow into oceans and a layer of sediments is created as the rock particles mix with soil and sink. 
- I will now melt and turn into magma!
- Compaction and Cementation occurs when layers of sediment stack up and the weight and pressure compacts the bottom layers. After years of compaction and cementation, the sediment turns into sedimentary rock.
- Metamorphism occurs when sedimentary or igneous rocks that are buried deep underground are exposed to high heat and pressure. They transform into metamorphic rocks. 
- Rock melting takes place when metamorphic rocks underground melt to become magma. When a volcano erupts, lava comes out. As the lava cools it hardens and becomes igneous rock. As soon as the new igneous rock is formed, the processes of weathering and erosion begin, starting the whole cycle over again!
