groin

Where the atmosphere and ocean are in contact, energy is passed from the moving air to the water through ____________.

emergent

The densest water in all of the oceans is formed in ____________ waters.

Antarctic

Other than wind, the most significant factor that influences the movement of ocean water is the ____________.

Coriolis effect

In the open sea, the movement of water particles in a wave becomes negligible at a depth equal to about ____________ the distance from wave crest to wave crest.

one-half

Deep-ocean circulation is referred to as ____________ circulation.

thermohaline

The large central area of the North Atlantic which has no well-defined currents is known as the ____________ Sea.

Sargasso

Highly irregular coasts with numerous estuaries frequently characterize a(n) ____________ coast.

submergent

The largest daily tidal ranges are associated with ____________ tides.

spring

Turbulent water currents within the surf zone that flow parallel to the shore are called longshore currents.

true

Evaporation and/or freezing tend to make the remaining water less salty.

false

The two most significant factors in creating a dense mass of water are temperature and depth.

false

Hard stabilization techniques used to reduce erosion along a coast include groins, breakwaters, and seawalls.

true

In the Southern Hemisphere, ocean currents form counterclockwise gyres.

true

The tide-generating potential of the Sun is slightly less than half that of the Moon.

true

Cold ocean currents often have a dramatic impact on the climate of tropical deserts along the west coasts of continents.

true

Ocean currents transfer excess heat from the tropics to the heat-deficient polar regions.

true

In the Northern Hemisphere, the Coriolis effect causes ocean currents to be deflected to the left.

false

The lowest daily tidal ranges are associated with neap tides.

true

In the open sea, it is the wave form that moves forward, not the water itself.
