Which best describes how ocean ridges form? a. decaying materials filter from above, creating ridges. b. corals grow on a submerged rim, forming circular ridges above the water. c. the flat action of the water shears off the top of a seamount, creating a ridge. d. pressure from lava being pushed up from the earth adds new material to the ocean floor, creating a ridge.

D.  Pressure from lava being pushed up from the Earth adds new material to the ocean floor, creating a ridge.
