Answer 2

Answer:

About 2.5 centimeter per year

Explanation:

At the divergent boundaries the earth lithospheric plates moves away from each other . This occurrence might be in the continental plate/crust or oceanic plates/crust. The divergent boundary can be noticed in the middle of an ocean . This is the type of boundary occurring in the Atlantic ocean. The diverging rate at the Atlantic ocean is very slow at about 2.5 cm per year. The plates are moving away from each other thereby causing the up-welling of magma to create a new oceanic crust.  The divergent boundary on the ocean floor like Atlantic ocean is usually found on the crest of the mid oceanic ridges. The boundary is also marked by shallow earthquakes and faults.
