Ocean Currents

What is the difference between waves and tides?

• Waves are caused by the gravitational pull of the moon, while tides are caused by the wind.

• Tides are caused by the gravitational pull of the moon, while waves are caused by the wind.

• Waves and tides are the same thing.

• Waves are permanent water currents, while tides are temporary changes in water direction.

What is defined as a large stream of water that flows through the oceans?

• Wave

• Tide

• Current

• Ripple

What is the primary function of ocean currents?

• To regulate global climate

• To produce marine energy

• To increase sea pollution

• To decrease marine biodiversity

What is the Coriolis Effect primarily responsible for in terms of ocean currents?

• The temperature of the currents

• The salinity of the currents

• The depth of the currents

• The curving/deflection of the currents

In which direction do currents flow in the Northern Hemisphere due to the Coriolis Effect?

• Counterclockwise

• Straight line

• Clockwise

• Inward

How do currents in the Southern Hemisphere move as a result of the Coriolis Effect?

• Clockwise

• Straight line

• Counterclockwise

• Outward

What causes surface currents in the oceans?

• The moon's gravitational pull

• Underwater earthquakes

• Winds and the spinning of Earth

• Marine life movement

What causes deep ocean currents in the oceans?

• The moon's gravitational pull

• Underwater earthquakes

• Winds and the spinning of Earth

• Differences in Density

How do surface currents generally move in the oceans?

• In a straight line

• In a zigzag pattern

• In circular patterns

• Randomly

Compared to deep ocean currents, the temperature of surface currents is usually:

• Colder

• The same

• Warmer

• Variable
