Is the force behind surface currents

What is the Wind

100
These are density driven.
What is a deep water current?
100
The highest part of the wave.
What is the crest?
100
The moons gravitational pull is the major contributor for these.
What are high and low tides?
100

Animals in the ocean use this to communicate.

What is sound?

200
There are 2 of these circular current patterns in the Northern Hemisphere.
What is a Gyre?
200
This brings nutrient rich water to the surface, therefore increasing biological productivity.
What is upwelling
200
The horizontal distance between two consecutive crests.
What is the wavelength?
200
Two high tides and two low tides in a 24 hour period are characteristic of this type of tidal pattern.
What is semi diurnal?
200

ROV stands for...

Remotely opperated vehicle

300

Something that float uses this type of force.

What is the positive buoyancy?

300
Name two factors that increase with depth.

What are density and salinity?

300
This shoreline would produce a spilling wave.
What is a gently sloping shoreline?
300
Tides that occur during the full and new moon phases are known as these.
What are spring tides?
300

This is the color of most ROVs.

What is yellow?

400

Looking to float? This sea is the best saltiest spot in the world.

What is the Dead Sea?

400

These currents are caused by changes in salinity and temperature.

What are thermohaline currents?

400
A type of wave caused by an earthquake.
What is a Tsunami?
400
This location has the highest tidal range in the world.
What is the Bay of Fundy?
400

Scientists may use this type of vehicle if they want to collect data by leaving it at sea for a long period of time.

What is an AUV?

500

This is a feature fish have in order to stay buoyant. 

What is a swim bladder?

500
The most dense water in the ocean currents have these 2 characteristics.
What are coldest and saltiest?
500

Wind duration, fetch and wind speed will determine this.

What is wave size?

500

The average salinity of the ocean is ___ ppt.

What is 35 ppt.

500

Explain why the poles are less salty than the rest of the ocean.

Because of iceburg melting
