Warm-up Week 2 # 1 ______ are associated with mid-ocean ridges. a. rift valleys c. extreme temperatures b. mountainous topography d. volcanic structures The gently sloping submerged surface extending from the shoreline toward the deep ocean is called ____. a. continental shelf c. continental rise b. continental slope d. submarine canyon Differences in ocean-surface height can be measured by ____. a. sonar c. submersibles b. satellites d. none of the above

“Seafloor Sediments and Resources” 14.3/14.4

Q: What processes create sediment in the Ocean? Turbidity Currents! Q: How else might sediment get into the Ocean?

Distribution of Sediment Coarse! Fine. Sediment covers most of the Seafloor. 1. Coarse = Beach 2. Fine = Ocean

Types of Ocean Sediment. Classified by Origin: (where from.) Terrigenous From Land Transported Biogenous From living things Yuck. Hydrogenous Minerals from Ocean Water

Any useful sediment deposits?... Energy Resources: Oil Natural Gas Gas Hydrates Water + Natural Gas! Most useful!

Other Ocean Resources… Sand & Gravel 2nd Most Important Economic Industry 1st = Oil.

Review. Which type of Sediment is likely to settle on the Ocean Basin Floor, far away from the coast? What are the 3 types of Ocean Sediment? Where does Biogeneous Sediment come from? Fine Sediment, Small Particle Size = CLAY Terrigenous, Biogenous, Hydrogenous Shells & Skeletons!
