Which action occurs at diverrgent plate boundaries?

a - metamorphic rock formation

b - seafloor spreading

c - mountain building

d - rock strata formation

The answer is d, strata formation. because the earth's ground, even under water, is always shifting, after some time, rock formations can occur. it can sink, create sink holes, crack apart, and residual rock & earth can form new strata.

Seafloor spreading occurs at divergent plate boundaries

Answer: Option B

Explanation:

At divergent plate boundaries where the plates diverge from each other, sea floor spreading takes place. Sea floor spreading is the formation of a new oceanic crust.

The volcanic activity results in the formation of a new oceanic crust. Once the new oceanic crust is formed, it separates itself from the ridge and the plate boundary where it was formed. The formation of the new oceanic crust causes the tectonic plates to diverge more and more.
