The amount of iron they contain. The lesson describes each rock and how it forms throughout the process. In some places, weathering and erosion occurs more often than in other. Rocks and the Rock Cycle. Erosion is an important factor in the rock cycle because it moves weathered rocks from one place to another by wind, ice, water, or gravity. The atoms and molecules in magma rearrange themselves into mineral grains.

Extrusive rocks occur in two forms: (1) as lava flows that flood the land surface much like a river and (2) as fragmented pieces of magma of various sizes (pyroclastic materials), which often are blown through the atmosphere and blanket Earths surface upon settling. igneous rock, any of various crystalline or glassy rocks formed by the cooling and solidification of molten earth material. Two moles of SiO2 are needed to be combined with one mole each of CaO and Al2O3 to make the calcium-rich plagioclase, CaAl2Si2O8 (anorthite).
