Metamorphic Rocks

Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming.

Some examples of metamorhic rocks are Quartzite, Slate, Marble

+info

Igneous Rocks

Some examles of igneous rocks are Obsidian, Granite, Pumice

Igneous rocks form when hot, molten rock solidifies.

+info

Sedimentary Rocks

Some examples of sedimentary rocks are Sandstone, Limestone, Shale

Sedimentary rocks are formed from weathered rock that settle in layers.

Transitions

Sedimentary rock may be broken down into sediment once again by weathering and erosion. It may also form another type of rock. If it becomes buried deep enough within the crust to be subjected to increased temperature and pressure, it may change into metamorphic rock.

On the surface, weathering and erosion break down the igneous rock into pebbles, sand, and mud, creating sediment, which accumulates in basins on the Earth's surface. As successive layers of sediment settle on top of one another, the sediment near the bottom is compressed, hardens, and forms sedimentary rock.

Transitions

Weathering is the process of breakdown of rocks through the action of wind, air, water and by the action of organisms. The metamorphic rocks get gradually converted into sedimentary rocks through this process. The big rocks change into small rock particles called sediments.
