The Rock Cycle
We have learned that igneous rock is formed when rock is melted and then cools, like the process that occurs when lava from a volcano cools. We demonstrated this process by melting and cooling chocolate. We also have learned that metamorphic rock forms when igneous rock and sedimentary rock are impacted by heat and pressure to form a new rock. We demonstrated this process by applying alot of pressure to broken up fruit chews to make a new form. Tomorrow we will learn about the sedimentary rock formations.
