What is the Gulf Stream current?

Back

The Gulf Stream 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

What are the causes of ocean currents?

Back

Ocean currents are caused by wind direction, differences in water temperature, and differences in salinity. Air pollution is NOT a cause.

Front

What is the deepest part of the ocean called?

Back

The deepest part of the ocean is called an ocean trench.

Front

How do temperature differences affect ocean currents?

Back

Cold water sinks while warm water rises, creating currents.

Front

At what depth might scientists make an error entering data?

Back

Scientists might make an error entering data at a depth of 1500 meters.

Front

What is an ocean trench?

Back

An ocean trench is a deep, narrow depression in the ocean floor, often formed by tectonic plate movements.

Front

What role does wind play in ocean currents?

Back

Wind drives surface currents in the ocean, affecting their direction and speed.

Front

What is salinity?

Back

Salinity is the measure of salt concentration in water, which can affect water density and currents.

Front

What is the continental shelf?

Back

The continental shelf is the underwater land that extends from a continent, usually shallow and rich in marine life.

Front

What is the continental slope?

Back

The continental slope is the steeply sloping area between the continental shelf and the deep ocean floor.
