Global Conveyor Belt

What is the role of the global conveyor belt in the world's food chain?

• It decreases the amount of nutrients in the water

• It has no significant role

• It increases water salinity

• It enriches surface waters with nutrients and carbon dioxide

What role do ocean currents play in the global climate?

• They have no effect on the climate.

• They only affect coastal regions.

• They distribute heat around the planet.

• They cool the planet by moving warm water to the poles.

What is the global conveyor belt?

• A large-scale ocean circulation system that moves warm and cold water around the globe.

• A method for predicting weather patterns globally.

• A system for transporting goods across continents.

• A type of oceanic plant that grows in warm waters.

How does the global conveyor belt affect ocean currents?

• The global conveyor belt drives the movement of ocean currents by redistributing heat and nutrients across the world's oceans.

• The global conveyor belt only affects freshwater systems, not ocean currents.

• Ocean currents are solely driven by wind patterns, not the global conveyor belt.

• The global conveyor belt has no impact on ocean currents.

What role does the global conveyor belt play in climate regulation?

• The global conveyor belt regulates climate by redistributing heat and influencing weather patterns.

• The global conveyor belt increases ocean acidity.

• The global conveyor belt only affects marine life.

• The global conveyor belt has no impact on climate.

What are some potential consequences of a disrupted global conveyor belt?

• Enhanced biodiversity in coastal regions

• More stable ocean currents

• Consequences include extreme weather, altered marine ecosystems, and impacts on food security.

• Increased global temperatures

What is the relationship between the global conveyor belt and carbon dioxide levels?

• Carbon dioxide levels are solely determined by atmospheric conditions.

• The global conveyor belt influences carbon dioxide levels by regulating oceanic absorption of CO2.

• The global conveyor belt only affects temperature, not carbon dioxide.

• The global conveyor belt has no effect on carbon dioxide levels.

How does pollution affect the global conveyor belt?

• Pollution has no impact on ocean currents or temperatures.

• Pollution disrupts ocean temperatures and salinity, affecting the global conveyor belt's circulation.

• Pollution increases ocean biodiversity, enhancing the global conveyor belt.

• Pollution only affects coastal areas, leaving the global conveyor belt unaffected.
