P1B Oceanic Conveyor Belt Quiz

What is the driving force behind the Oceanic Conveyor Belt?

• Winds and density differences

• Tides and currents

• Solar radiation and precipitation

• Volcanic activity and earthquakes

How long does it take for one complete circuit of the Oceanic Conveyor Belt?

• 100 years

• 500 years

• 1,000 years

• 10,000 years

Which current is created by the Gulf Stream flowing across the Atlantic to the coast of Europe?

• North Atlantic Drift

• Kuroshio Current

• Agulhas Current

• Brazil Current

What happens to the Gulf Stream near Iceland?

• It becomes warmer and less saline

• It sinks to the bottom of the North Atlantic

• It splits into two parts

• It flows into the Indian Ocean

What happens to the deep-sea current flowing around Antarctica?

• It becomes warmer and less saline

• It splits into two parts

• It flows into the Pacific Ocean

• More dense cold and saline water is added to it

What causes the two currents in the Indian and Pacific Oceans to rise to the surface?

• Warmer and less saline water

• Strong winds

• Volcanic activity

• Tidal forces

What is the impact of the warm Gulf Stream on coastal regions of Western Europe?

• Decreased temperatures and precipitation

• Increased temperatures and precipitation

• No impact on temperatures and precipitation

• Increased temperatures and decreased precipitation

What does the oceanic conveyor belt bring to the surface by upwellings of deep-sea currents?

• Carbon dioxide

• Oxygen

• Nutrients

• Salt

What role does the oceanic conveyor belt play in carbon dioxide distribution?

• It removes carbon dioxide from the atmosphere

• It releases carbon dioxide into the atmosphere

• It has no impact on carbon dioxide levels

• It converts carbon dioxide into oxygen

Why is the oceanic conveyor belt important for ecosystems in the surface waters?

• It provides nutrients

• It regulates temperature

• It controls salinity

• It increases oxygen levels
