Three Types of Rock: Igneous, Sedimentary Metamorphic | AMNH

Three Types of Rock: Igneous, Sedimentary Metamorphic | AMNH

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. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineralladen water. Most rocks are made of minerals containing silicon ...

Sedimentary rock

Sedimentary rock

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological ...

How Are Metamorphic Rocks Formed?

 · Metamorphic rocks are rocks that have changed from one type of rock to another. While sedimentary rock is formed from sediments, and igneous rock is formed from molten magma, metamorphic rock is rock made from preexisting rocks. These rocks undergo a change, either caused by high heat, high pressure, or exposure to mineral rich hot liquid, which transforms the existing rock .
