Kids Geo has an interactive image that allows visitors to use the mouse to highlight the various parts of the rock cycle. Rocks In A Hard Place has a diagram of the rock cycle as well.Continue Reading
Annenberg Learner offers a free interactive website where students can learn about rocks and the rock cycle. It even includes an assessment that explores various parts of the rock cycle.
The rock cycle includes three main types of rocks, igneous, sedimentary, and metamorphic. Each type of rock is formed in different ways, and each type of rock can be turned into another type of rock. The rock cycle is the process that makes and recycles rocks.
Igneous rocks are formed when magma cools and solidifies into rocks. Weathering and erosion causes igneous rocks to break into smaller and smaller pieces. Wind and water carry the small pieces to piles called sediment beds. The sediment beds eventually get buried, and the rock in them cements together, creating sedimentary rocks. If the sedimentary rock gets buried in the Earth, heat and pressure bake it, turning it into metamorphic rock.
Metamorphic rock can also be eroded to form sedimentary rock. If it becomes buried even deeper in the Earth it can melt and become magma. When the magma solidifies it forms an igneous rock.Learn more about Geology
