ocean current_2_16.1

What is the primary driving force behind surface ocean currents?

• Temperature changes

• gravitational force

• wind

• Eaerthquakes

What primarily drives deep ocean currents?

• Marine animal migration

• Seismic activity on the ocean floor

• Wind patterns

• Density differences in the water

Which factor contributes to the thermohaline circulation in the ocean?

• Salinity variations

• Solar radiation

• Wave action

• Coastal erosion

What is the effect of the Coriolis force on ocean currents?

• It causes currents to flow in a straight line

• It deflects currents to the right in the Northern Hemisphere

• It has no effect on ocean currents

• It increases the speed of currents

How do ocean currents influence global climate?

• By redistributing heat around the planet

• By increasing rainfall in coastal areas

• By reducing wind speeds

• By creating underwater volcanoes

How do ocean currents affect marine biodiversity?

• By providing nutrients to surface waters

• By increasing ocean temperatures

• By reducing the number of fish species

• By creating barriers to migration

Which phenomenon is caused by the interaction of ocean currents and wind?

• El Niño

• Ocean acidification

• Coral bleaching

• Thermal expansion

How does the Coriolis effect influence ocean currents?

• It deflects ocean currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

• It causes ocean currents to move in a straight line across the globe.

• It increases the speed of deep ocean currents.

• It has no effect on ocean currents.

What role do ocean currents play in regulating sea surface temperatures?

• They have no significant impact

• They help to maintain consistent temperatures

• They only affect temperatures in the polar regions

• They increase temperature fluctuations

Which of the following is a consequence of changes in ocean currents?

• Altered weather patterns

• Increased volcanic activity

• Decreased salinity levels

• More frequent earthquakes
