What are the 3 basic types of rocks?

There are three kinds of rock: igneous, sedimentary, and metamorphic. 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.

Which cools faster magma or lava?

When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface. … This magma will also cool, but at a much slower rate than lava erupting from a volcano. The kind of rock formed in this way is called intrusive igneous rock.
