T/F Oceanagraphy

Marine algae is classified based on its color

True

Blue light penetrates the ocean more than red light

True

Ocean bottom water always contains more nutrients than surface water

True

Mangroves act to prevent coastal erosion

True

Kelp is a vascular plant

False

Coral polyps open during the day to photosynthesize

False

Most bioluminescence is red

False

Most organisms in the deep ocean are red in color

True

Toothed whales are generally larger than baleen whales

False

The steady increase in fishing yields indicates that fish populations have been increasing

False

H.A.B.s are caused by low oxygen levels

False

Prey fish school to pray for their survival

False

In the seasonal seas, there is a strong productivity spike in the summer when nutrient-levels are at their highest levels

False

The primary reason whales travel such great distances in the ocean is to take advantage of intense productivity in the high latitudes

True

Most beaches will be eroded in the summer and build-up in the winter

False

Metabolic rate increases with increasing temperature

True

Biological amplification increases with each trophic level

True

The amount of energy increases at each trophic level

False

Tidal inlets are maintained by tidal currents and are often "closed-off" by longshore transport.

True

Tides promote water exchange between estuaries and the open ocean

True

Narrow continental shelves occur at passive continental margins

False

Active continental margins are often associated with rocky coasts

True

Passive continental margins loose sand to the deep ocean

False

Steep beach profiles are associated with fine beach sand

False

Land animals come to the coast to breed

False

Warm core eddies in the Atlantic rotate clockwise

True

Eddies off the southern tip of Africa rotate clockwise

False

As wave period increases wave frequency also increases

False

Perihelion spring tides are associated with a large tidal range

True

Tides promote water exchange between estuaries and the open ocean

True

Equatorial tides are notably "small" tides

True

Wave refraction occurs because waves slow down in shallow water

True

Coriolis causes cold and warm core eddies to rotate in opposite directions

False

Spilling waves indicate a steep off-shore area

False

A wave with a wavelength of 50 meters will have a wave base of 100 meters

False

Condensation releases heat

True

Warm air can hold more moisture than cold air.

True

When a gas expands it cools

True

It gets colder with altitude due to a decrease in atmospheric pressure.

True

Solar heating causes atmospheric circulation

True

High pressure occurs at 30 degrees N & S latitude where chronic upwelling occurs

False

Westerlies occur because Coriolis deflects surface winds to the west (in the Northern Hemisphere)

False

In the Northern Hemisphere low pressures systems rotate in a clockwise sense

False

The summer monsoon is due to preferential heating of the land relative to the ocean

True

The winter monsoon is a result of warm land temperatures and cool ocean temperature

False

During the winter monsoon, a high pressure system is located over Asia

True

Trade winds blow from west to east on both sides of the equator

False

It is thought that the loss of Arctic Sea Ice will speed-up atmospheric circulation.; False

A sea breeze occurs due to preferential heating of the land

True
