The rock cycle also is dependent upon the tectonic cycle for energy and the hydrologic cycle for water. The three main types of rocks are igneous, sedimentary, and metamorphic. The igneous rock is formed from the internal heat of the tectonic cycle from molten material near the surface. Also, they can be formed from the melting of sedimentary or metamorphic rocks. The weathering and erosion of igneous rocks transform them into sediments. Sedimentary rocks are found and formed wherever sediments are stored or found. Some places that sedimentary rocks accumulate are the bottom of oceans, low-lying coastal deltas, and river channels. Sedimentary rocks are typically formed from the breakdown or weathering (chemical or physical) of other rocks. Lastly, metamorphic rocks are formed when heat, pressure and chemical reactions alter igneous or sedimentary rocks. Metamorphism occurs when heat, pressure, or
