3.2 Ocean Currents

Front

What is the Gulf Stream?

Back

The Gulf Stream is a warm ocean current that carries warm water from the east coast of the United States to the west coast of Europe.

Front

What weather phenomenon can cause increased flooding on the California coast?

Back

El Niño years can cause increased flooding on the California coast.

Front

What is upwelling in ocean currents?

Back

Upwelling is the process where winds cause warm surface water to be replaced with colder, nutrient-rich water.

Front

What causes an increase in density in ocean water?

Back

An increase in density can occur when warm water loses energy to its surroundings and cools.

Front

How do ocean currents affect global climates?

Back

Ocean currents can influence climate by transporting warm or cold water to different regions, affecting temperature and weather patterns.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects, such as ocean currents, due to the rotation of the Earth.

Front

What is the difference between surface currents and deep ocean currents?

Back

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

Front

What role do ocean currents play in marine ecosystems?

Back

Ocean currents help distribute nutrients and organisms, supporting diverse marine ecosystems.

Front

What is the significance of the thermohaline circulation?

Back

Thermohaline circulation is a global system of ocean currents driven by temperature and salinity differences, crucial for regulating climate.

Front

What is the impact of melting icebergs on ocean currents?

Back

Melting icebergs add fresh water to the ocean, which can affect water density and disrupt ocean currents.
