Question

The type of plate boundary where plates move apart, resulting in upwelling of material from the mantle to create new seafloor, is referred to as a _____ plate boundary. oceanic-oceanic divergent transform fault convergent

Answer 1

divergent plate boundary

Answer 2

The correct answer is - divergent.

The divergent plate boundaries are the boundaries formed at the places where two tectonic plates are moving away from one another. Because the plates are moving away from one another, they open up a gap, and the crust in this part is becoming much weaker. The weaker crust enables the high pressure and high temperatures from the mantle to crack it, and the magma to rise towards the surface. As the magma reaches the surfaces, it cools down and creates the new crust in the form of igneous rocks.
