Whatever drives the movement, plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed ...

As the overlying plate lifts up, it also forms mountain ... that eventually build up into island arcs like Japan. At divergent boundaries in the oceans, magma from deep in the Earth's mantle ...

Longest mountain range, running through the Atlantic Ocean, separating the Eurasian and North American plates in the north, ...

Underwater, though, submarine mountains usually form as two plates drift apart at a so-called divergent boundary and magma spews out. But far away from these plate boundaries, at the center of ...

Four types of plate tectonic activity are demonstrated in this feature. Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ...

In regions of convergence, one plate can sink under another in a subduction zone, or two colliding plates can form a mountain belt. At divergent boundaries, plates move away from each other and ...

Geodynamics Modeling; Large Igneous Provinces and Global Climate Perturbations; Tectonics and Magmatism at Large Igneous Provinces and Divergent Plate Boundaries I have intrinsic motivation in ...

This is called a constructive or divergent plate boundary. These are usually found under oceans. As the plate moves apart, magma rises to the surface and cools, forming shallow-sided volcanoes.
