Document Summary

Echo sounder sends sound waves and a receiver will reflect the signal down to the ocean floor. There are mountain ranges on the sea floor almost as high as the mountain ranges on land. Continental shelf: gentle gradient to about 130m depth. Continental slope: steeper slope beyond the shelf. Continental rise: gentle slope under deep sea fan sediments. Valleys carved by rivers into the continental slope during lower sea level or by turbidity currents. Active: at subduction zones with deep-ocean trenches and accretionary wedges. Deep-ocean trenches: at the edges of subduction zones. Abyssal plains: flat hide rugged terrain covered with fine seds. Reef: skeletal remains of corals that grow in warm sunlit sea water up to 45 m deep. Submarine ridge system with wide rift valleys that are offset by transform faults.
