Classical plume models offer insights into intraplate volcanism and seamount chain formation by assuming a cylindrical upwelling of hot materials from the core-mantle boundary. The interaction of ...
While seafloor spreading and subduction explain much of the volcanic activity in Earth’s oceans, magmatism occurring within tectonic plate interiors requires a deeper mantle explanation. Various types ...
Over 40,000 seamounts—undersea mountains that don't breach the ocean's surface—are scattered across the ocean floor. Some ...
