what causes equatorial open ocean upwelling? select one: a. heavy rainfall b. high primary productivity c. converging surface currents moving toward the equator in both hemispheres d. diverging surface currents moving away from the equator in both hemispheres e. strong solar heating

Converging surface currents moving toward the equator in both hemispheres causes equatorial open ocean upwelling.Currents may transport cold, deep ocean water to the surface through a process called upwelling. Winds and the rotation of the Earth cause upwelling. The open ocean close to the equator experiences upwelling as a result of the Coriolis phenomenon. At the equator, trade winds move surface water both north and south, allowing deeper water to upwell.On its axis, the Earth revolves from west to east. Winds have a tendency to veer right in the northern hemisphere and left in the southern hemisphere as a result of this rotation. The Coriolis effect, which dominates upwelling in coastal areas, is what is known as it.Learn more about Coriolis Effect here:https://brainly.com/question/1557014#SPJ4
