Ocean Floor, Plate Tectonics, Water Test Review
Ocean Floor
 Seafloor (ocean basin) features:
- abyssal plain (deep-sea - continental slope
floor)
- fracture zone
- continental rise
- guyot
- continental shelf
- island arc



Test date: _____________
-
mid-ocean ridge
seamount
submarine canyon
trench
Ocean basin versus continents – BE SPECIFIC (use numbers where required!)
­ Rock composition, density, thickness
Layers of the earth (Crusts, upper mantle (flowing and rigid), lower mantle)
Mapping the ocean floor (Be able to plot data and identify seafloor features)
Plate Tectonics
 Plate tectonics - Continental drift:
­ Pangaea, Alfred Wegener
­ Evidence to support his idea (fossils, rock age/type, continent shapes)
 Boundaries:
­ Diverging, converging, sliding
­ Types of convergent zones
- ocean-ocean - ocean-continent (subduction) - continent-continent (collision)
 Features at plate boundaries
­ Mountain, volcanoes, trenches, valleys and (earthquakes)
 Plate names (ocean names)
African plate
Indo-Australian plate Pacific plate
Antarctic plate
Juan de Fuca plate
Philippine plate
Caribbean plate
Nazca plate
Scotia plate
Eurasian plate
North American plate South American plate
 Seafloor spreading (Henry Hess, new crust is formed)
Water
 Water cycle (condensation, evaporation, precipitation)
 Distribution of water (know the %)
- rivers, lakes, ponds
- groundwater - oceans and seas
- glaciers, ice sheets
 Properties of water
- surface tension
- universal solvent - freezing
- evaporation
- freezing point
- light absorption
- melting
- condensation
- frost formation
- heat capacity
- sublimation
- triple point
- hydrogen bonds
- adhesion
- cohesion
- density
Q – what properties does water have that other liquids do not?
 Properties of saltwater (seawater)
­ Salinity (units: o/oo) - How does the salt get there? Where does it go?
­ Depth effect on density, temperature, salinity
­ Density compared to fresh water, change in buoyancy
