True:
- The majority of igneous rock is formed beneath the surface. — Most igneous rock by volume is intrusive (plutonic) rock that cooled slowly underground.
- A large amount of igneous rock can be found near tectonic plate boundaries. — Volcanism and magma generation at divergent and convergent boundaries produce lots of igneous rock.
- Magma is made up of rock that has been melted. — Magma is molten rock (often with crystals and dissolved gases) below the surface.
- Igneous rock is formed through the cooling and solidification of molten materials. — This is the defining process for igneous rocks.
False:
- The majority of igneous rock is formed on the surface of the Earth. — Surface (extrusive) igneous rocks exist, but they are smaller in volume than the intrusive rocks formed beneath the surface.
