Front

Surface currents are a result of: Global Wind Patterns, Earth's Rotation, Density, All of the above

Back

Global Wind Patterns

Front

Which object in the solar system has the greater effect on Earth's tides? Options: Sun, Saturn, Moon, Venus

Back

Moon

Front

What is an upwelling?

Back

Wind current push away surface water, allowing deep water to flow up.

Front

Ocean water with a high salinity is...

Back

more dense and sinks

Front

Which of the following is not a process that decreases the salinity of seawater? runoff from land, icebergs melting, precipitation, evaporation

Back

evaporation

Front

How does excess (too much) carbon dioxide in the atmosphere change the ocean?

Back

it reduces the pH of the water making it more acidic

Front

The food web in the ocean can be disrupted by changes in the gas concentrations in the atmosphere, such as carbon dioxide.

Back

true

Front

What is the main way energy is transferred (moved around) in the ocean? Options: conduction, radiation, convection, whales mix it up

Back

convection

Front

How can ocean surface currents affect continents? Options: draw water away from the land, cause more frequent precipitation, cause more frequent flooding, make the coast warmer during the winter and cooler during the summer

Back

make the coast warmer during the winter and cooler during the summer

Front

The densest seawater flows along the seafloor. It is most dense because it is

Back

very cold and very salty
