Rock Cycle

Rock Cycle By: Woudloper/Woodwalker

The rock cycle is the process in, which rocks change into different forms of rock, through processes like weathering and erosion. There are three types of rock, Sedimentary, Metamorphic, and Igneous. An important part of the rock cycle is any form of rock can change into any other form of rock. When a rock goes through weathering and erosion, then compression and compacting it turns into Sedimentary rock. When a rock goes through a lot of heat and pressure it turn into a Metamorphic rock. When a rock melts, and then it cools, it turns into an, Igneous rock.

SP2: Developing and using models
The model we used in class was a version of the rock cycle, where a student represents a rock in the rock cycle and we roll a dice to see where we are going next. Another model we used was gizmo that helped use describe the processes a rock goes through during the rock cycle, it also helped us see that there are various smaller cycles in the rock cycle.

XCC: Patterns
A pattern we observed in class, was the pattern that we use to find out the relative age in rocks, as in the age of a rock compared to the ones around it. The pattern that we saw was that, when rocks appear on multiple layers, those layers must be next to each other. If a rock is on one layer, but not the next then that rocks lifespan is over (We use fossils found in the rocks lifespans). Using these patterns we can find out the relative age of a rock.
