Which statement is true about this picture?
this is a volcanic ridge along a convergent plate boundary.
this is a divergent plate boundary which traps magnetic polarity reversals as the lava cools.
this is a divergent plate boundary showing layers of new rock and old rock.
this is a divergent plate boundary which causes changes in magnetic polarity by forming a mid ocean ridge.

This is a divergent plate boundary which causes changes in magnetic polarity by forming a mid ocean ridge

Explanation:

There are three main types of tectonic plate boundaries they are as follows:

Convergent boundaries : Here two plates collide with each other.

Divergent boundaries : Here two plates are moving apart

Transform boundaries: two plates slide pass each other

Divergent boundaries: the space is filled with molten magma. It forms within the continents and finally open up to form ocean basins.

On land divergent boundaries produces rifts in continents.

Under the sea: the most active plates are between the oceanic plates are often called mid-oceanic ridges
