e. SST (sea surface temp)- Water temp close to the surface
f. Tides
1. Ebb Tide- The receding or outgoing tide
2. Flood Tide- The incoming or rising tide
3. High Tide-When sea level is at its highest point.
4. Low Tide- When sea level is at its lowest point.
g. Currents
1. Open ocean- Refers to the motion of the ocean water driven by tides, winds or differences in density.
2. Littoral- Current produced by the transport of the water caused by the breaking action of the waves that strikes a beach.
3. Rip- Strong channel of water flowing seaward from near the shore cause by the piling up of water along the shore when waves are parallel to the shore.
h. Surf zone- The area from the water up rush outward to the point which waves first show any indication of breaking..
i. Breaker type
1. Spilling- Occurs with a gentle and flat beach slope. Crest of wave undergoes deformation and destabilizes, resulting in spilling over front of wave
2. Plunging- Crest of wave curls over and crashes into base of wave, creating sizable splash and occurs with moderate to steep beach slopes.

j. Ocean fronts- Ocean boundaries between water masses of different density

k. Ocean bottom
1. Topography- The configuration of the of the sea floor and ocean surface.
2. Composition- What the ocean floor is made up of (rocks, silt, sand, ect.)
