Unit 4 TEST

Front

What is the Gulf Stream Current?

Back

The Gulf Stream Current is a warm ocean current that originates in the Gulf of Mexico and flows up the eastern coast of the United States, influencing climate and weather patterns.

Front

When is seawater the densest?

Back

Seawater is densest when salinity is high and its temperature is low.

Front

What creates ocean tides?

Back

Ocean tides are created by the gravitational pull of the Sun and Moon on Earth's water.

Front

Why do bodies of water in Georgia evaporate more quickly than those in New England?

Back

Bodies of water in Georgia evaporate more quickly because the temperature of the water is warmer along the Georgia coast.

Front

What does the continental slope symbolize in oceanography?

Back

The continental slope is represented by the number 2 in oceanographic illustrations.

Front

What is salinity?

Back

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

Front

How does temperature affect water density?

Back

As temperature decreases, water density increases; colder water is denser than warmer water.

Front

What role does the Moon play in ocean tides?

Back

The Moon's gravitational pull causes the water on Earth to bulge, creating high tides.

Front

What is the difference between ocean currents and tides?

Back

Ocean currents are continuous flows of water in the ocean, while tides are the periodic rise and fall of sea levels caused by gravitational forces.

Front

What is the North Atlantic Drift?

Back

The North Atlantic Drift is a warm ocean current that extends from the Gulf Stream across the Atlantic Ocean, affecting the climate of Western Europe.
