How does downwelling support life
WebCurrents are powerful physical forces in the seas. They move water and heat around the globe, and help determine the chemical make-up of the water column. Currents also are a major factor in ocean ecosystems. Two types of current motion, upwelling and downwelling, strongly influence the distribution and abundance of marine life. Upwelling. WebUpwelling causes sea level to lower along the coast and rise further out to sea. Downwelling causes sea level to rise on the coast but lower out to sea.
