Ocean Currents, Tides and Waves Test

Front

What is upwelling?

Back

Upwelling is the process by which deep waters rise to the surface when surface currents separate, bringing nutrients to the surface.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the phenomenon that causes moving objects, like water, to turn and twist rather than move in a straight line due to the rotation of the Earth.

Front

How do water particles behave in a wave?

Back

Water particles in a wave move in a circular pattern, rising and falling as the wave passes.

Front

What type of water does the Gulf Stream carry?

Back

The Gulf Stream carries warm water from the east coast of the United States to the west coast of Europe.

Front

What shape do ocean currents typically follow?

Back

Ocean currents typically flow along curved paths due to the movement of the Earth and winds.

Front

What is thermohaline circulation?

Back

Thermohaline circulation is the large-scale movement of water driven by differences in temperature and salinity, affecting global climate.

Front

What causes tides?

Back

Tides are caused by the gravitational pull of the moon and the sun on Earth's oceans.

Front

What is the difference between a wave and a current?

Back

A wave is a disturbance that moves through water, while a current is a continuous flow of water in a particular direction.

Front

What is the role of wind in wave formation?

Back

Wind transfers energy to the water surface, creating waves as it pushes against the water.

Front

What is a tidal range?

Back

The tidal range is the difference in height between high tide and low tide.
