answer explanation . Extrusive igneous rocks form when magma reaches the Earth's surface a volcano and cools quickly. Metamorphic rocks form when any existing rock undergoes … igneous rocks form from magma that erupted onto the surface as lava, where it cooled quickly. Sedimentary rock are neither intrusive or extrusive. Magma is molten (liquid) rock under Earth’s surface. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Extrusive igneous rocks are formed by cooling the molten magma on the surface of the Earth. Because of this slow cooling process, crystals in the rock have more time to form, and are therefore larger and usually visible to the naked eye. Extrusive rocks, because of their small crystals and glass, are less durable.
