RockCycle
Storyboard Text
- I am rocky. I am now an igneous rock. I was formed from cooling and hardening of magma and lava.When the magma or lava cools,it may crystallize and harden, a process known as solidification.The rock that forms as a result is known as igneous rock.I have a glassy texture.
- This is me! I was broken down into sediments due to weathering and erosion. Wind and water gather sediments into a pile called sediment bed.
- If I move deeper into the Earth in the form of a metamorphic rock then I will have to melt and become back to magma. In this stage, I have ribbon like layers. Stratification,the layering that occurs in most sedimentary and igneous rocks formed at the earths surface,as from lava flows and volcanic fragmental deposits.
- Overtime the sediment beds get buried. The pieces of rock become cemented together to form sedimentary rock. Now I am a sedimentary rock due to compaction and cementation. I look like a crystal rock in this stage!!
- If I could stay in the same spot without getting buried, due to erosion and weathering I will change into a sediments again.
- If I get buried in the Earth, I will have to undergo metamorphosis. That means the heat and pressure from the Earth will bake me into a new rock called metamorphic rock. In this stage, I have ribbon like layers.
- When the magma cools down I will again become an igneous rock. This is how my life works, the rock cycle.
- I started my life as an igneous rock which happenend when magma cooled and hardened, but by a process called weathering it became sedimentary rock. While I was buried, I went through metamorphosis. Heat and pressure made me a metamorphic rock. If I go deeper into the Earth, I will have to undergo melting and become magma again thus the rock cycle continues.
