Question

why are divergent plate boundaries Constructive ​

Answer 1

Answer:

A constructive plate boundary, sometimes called a divergent plate margin, occurs when plates move apart. Volcanoes are formed as magma wells up to fill the gap, and eventually new crust is formed. An example of a constructive plate boundary is the mid- Atlantic Ridge .

Answer 2

Answer:

Generally, beneath the ocean, two plates move apart resulting in gushing out of magma from the interior of the earth. This magma or lava, on cooling forms new crust (plates) and mid- ocenic ridges at the bottom of the ocean. The plate boundary is known as divergent or constructive plate boundary.
