Unit 9 : Oceanography TEST Review

Front

What are spring tides?

Back

Spring tides are tides that occur when the moon, Earth, and sun are aligned in a straight line, resulting in a larger tidal range.

Front

What causes high salinity in the Mediterranean Ocean?

Back

High salinity in the Mediterranean Ocean is primarily caused by high evaporation rates.

Front

What is the Gulf Stream?

Back

The Gulf Stream is a warm ocean current that influences weather along the east coast of the U.S. and up toward Europe.

Front

What are neap tides?

Back

Neap tides are tides that have a smaller range and occur when the sun and moon are at right angles to each other.

Front

How does ocean depth affect temperature and density?

Back

As ocean depth increases, the temperature gets colder and the density becomes more dense.

Front

What is oceanography?

Back

Oceanography is the study of the ocean, including its ecosystems, currents, and the physical and chemical properties of seawater.

Front

What is salinity?

Back

Salinity is the measure of the amount of salt in water, usually expressed in parts per thousand (ppt).

Front

What is the role of ocean currents?

Back

Ocean currents help regulate climate by distributing heat around the planet and influencing weather patterns.

Front

What is the difference between surface currents and deep currents?

Back

Surface currents are driven by wind and affect the upper layer of the ocean, while deep currents are driven by differences in water density and temperature.

Front

What is upwelling?

Back

Upwelling is the process where deep, cold, nutrient-rich water rises to the surface, supporting marine life.
