Which plate boundary and movement commonly create ridges, like the mid-atlantic oceanic ridge? explain how ridges can be created by plate tectonics.

A constructive plate boundary creates ridges

Explanation: A constructive plate boundary, sometimes called a divergent plate margin, occurs when two tectonic plates move apart. Volcanoes are formed as magma wells up to fill the gap and molten rocks from the mantle below spread out and harden, eventually forming a ridge of new land/rock. The Mid-Atlantic ridge is an example of a constructive plate boundary.

Hope this helped x

Divergent boundaries because I just know and because that’s how it opens
