Oceans Review
4-Spheres-how they are interconnected and how they relate to one another.
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.
