Lesson 2.2 Ocean Floor *Refer to Chapter 3 in your Textbook

Learning Goals: I can identify & label the ocean zones I can label & identify ocean floor features I can describe the composition of the seafloor

Ocean Zones Hortizontal: Intertidal Zone: area closest to shore, covered during high tide and exposed to air during low tide Neritic Zone: extends from the intertidal zone to the continental shelf Oceanic Zone: extends from the continental shelf to the end of the continental slope

Ocean Zones Vertical: Pelagic Zone: “open ocean” Photic: portion of the pelagic zone with sunlight Aphotic: portion of the pelagic zone without sunlight Benthic Zone: “bottom of ocean,” ocean floor Hadal Zone: below the bottom of the ocean floor (trenches)

Ocean Floor Bathygraphic features: are the physical features of the ocean VS Topographic features of land Ocean Floor Divided into 2 regions: Continental Margin: from continental shelf to rise Ocean Basin: from continental rise to open ocean

Continental Margin: Continental Shelf: top of margin Continental Slope: sharp drop from shelf Continental Rise: bottom of slope, gradual drop Submarine Canyon: deep cut in continental margin

Ocean Basin: Abyssal Plains: flat ocean bottom Seamounts: single underwater pointed mountain Guyots: single underwater flat mountain Trenches: deep cut in the ocean floor Ridges: a continuous series of underwater mountains

Ocean Basin

Composition of the Ocean Floor Basalt rock covered by a layer of sediment Types of Sediment: Hydrogenous: forms from chemical processes in the seawater Biogenous: forms from the shells & skeletons of living organisms Terrigenous: carried into the ocean from the land Cosmogenous: particles from outer space
