Work for Mrs. Freeman's science class. 4/4/13
Alright class today we are going to learn about the rock cycle. What are the tree main rock types?
Igneous, sedimentary and metamorphic.
Step 1. When Igneous rocks weather and erode, it creates sediments.
Step 2. The water moves sediments and after a long time layers form on top.
Step 3. These sediments go through cementation and heat and pressure squeezes them into sedimentary rocks.
Final Step. Then because of heat and pressure they turn into metamorphic rocks. then, depending on location they melt into lava or magam and cool into igneous rocks.
So what did u learn today?
I learned about the rock cycle!
