P567 at Port Ellen Primary have been doing Geology. This includes learning about rocks. So, we learned about how all the rocks are formed. They are formed by a cycle which is the Rock Cycle. There are 3 types of rock groups: Sedimentary rock, Metamorphic rock and Igneous rock. First, little broken up pieces of rocks, called Sediments cement and compact together to make Sedimentary rock. Sedimentary rock then heats up and gets lots of pressure building up on it. Then it turns into a Metamorphic rock. Next the Metamorphic rock travels to the core of the Earth and melts into magma. When magma crystallizes, it makes Igneous rock. Finally, Igneous rock then experiences Weathering, Erosion and Depostition. Then the Igneous rock turn back into Sediments. Then, It starts again. The process of the rock cycle takes millions of years to complete. When we were learning about the Rock Cycle, we all made A3 posters and we drew a diagram on the Rock Cycle. I thought learning about The Rock Cycle was really fun.
