Oceans Review 4-Spheres-how they are interconnected and how they relate to one another. Geosphere Biosphere Atmosphere Hydrosphere Mapping the Ocean Floor Echo profiling/echo sounding Plotting Data- D=VxT (divided by 2) Ocean Topography (labelling and identifying) -know how to draw both Atlantic and Pacific Ocean floor Continental shelf, slope and rise, trench, submarine canyon, seamount, guyot, mid-ocean ridge, rift valley, abyssal plain. Active Continental Margin vs Passive Continental Margin Sediments: 4 kinds and how they are created Tectonic Plates: Features of Plate Boundaries -difference between Oceanic and Continental Crust-what they are made of (granite (cc)/Basalt (oc) 1. Convergent: Two plates colliding (Ocean-ocean, ocean-continent) Subductioncreates deep ocean trenches. Know how to draw. 2. Divergent: Two plates moving away from each other- Creates new oceanic crust at mid-oceanic ridge. 3. Transform: Two plates are sliding against each other. Earth’s Interior -Crust/mantle/outer core/inner core -Lithosphere/asthenosphere/mesosphere/ core -Know density/location and state (solid, liquid etc…) Seismic Tomography -how do scientists use this to visualize the layers of the earth.
