Ocean Currents, Tides and Waves Test

Front

What happens to a current when it comes in contact with a continent or landmass?

Back

It changes direction.

Front

How do warm-water currents affect the coastal areas along which they flow?

Back

They warm the coast.

Front

What type of tides are created by the alignment of the Earth, Moon, and Sun during a full moon or new moon?

Back

Spring tide.

Front

What is responsible for the Earth's tides?

Back

The gravitational pull of the sun and moon.

Front

Where do cold ocean currents generally originate from?

Back

Either Pole.

Front

Define ocean currents.

Back

Large-scale movements of water within the world's oceans, driven by factors such as wind, temperature, salinity differences, and the Earth's rotation.

Front

What is the difference between a neap tide and a spring tide?

Back

Neap tides occur when the sun and moon are at right angles to each other, resulting in lower high tides and higher low tides; spring tides occur when the sun and moon are aligned, resulting in higher high tides and lower low tides.

Front

What is the Coriolis effect?

Back

The deflection of moving objects, such as ocean currents, caused by the rotation of the Earth.

Front

What role do ocean currents play in climate regulation?

Back

They help distribute heat around the planet, influencing weather patterns and climate.

Front

What is thermohaline circulation?

Back

A global system of surface and deep ocean currents driven by temperature and salinity differences.
