When soil and surface materials erode over time, they leave layers of sediments. Over long periods of time, layer upon layer of sediments form, putting intense pressure on the oldest layers. Under great pressure and heat, lower layers of sediments eventually turn into rocks.
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.
