Ocean Currents

What effect could global warming have on the global conveyor belt?

• It could slow down the conveyor belt
• It could strengthen the conveyor belt
• It could cause the conveyor belt to collapse
• It could have no effect on the conveyor belt

What is the hydrological cycle?

• The process of water evaporation
• The movement of water on Earth
• The process of water filtration
• The movement of water in the oceans

What drives the global conveyor belt?

• Wind patterns
• Tides
• Differences in water density
• Earth's rotation

What is the global conveyor belt?

• A system of ocean currents that distribute heat energy
• A device used to measure water density
• A type of fishing net used to catch marine animals
• A large belt made of plastic that floats in the ocean

What is the impact of warm water moving towards the Polar Regions on the air temperature?

• It decreases the air temperature
• It has no effect on the air temperature
• It increases the air temperature
• It fluctuates the air temperature

How does temperature affect water density?

• Temperature has no effect on water density
• Warmer water is more dense
• Water density is only affected by salinity
• Colder water is more dense

What happens to water density as it warms?

• It fluctuates
• It increases
• It remains the same
• It decreases
