Rocks and the Rock Cycle: Complexities of the Rock Cycle

The video explains the rock cycle, highlighting how sedimentary and igneous rocks can melt into magma, and how sedimentary rocks undergo weathering to form sediment. It also covers how igneous and metamorphic rocks transform under heat and pressure into metamorphic rocks, using granite and gneiss as examples. The rock cycle is depicted as a complex web of ongoing changes.

Describe the process by which igneous rocks can transform into metamorphic rocks.

How does the rock cycle illustrate the concept of continuous change in rocks?
