• Nutrients move from warm, shallow areas to deep, colder areas.

• Nutrients move from warm, shallow areas to deep, colder areas.

• Nutrients move from deep, colder areas to warm, shallow areas.

Multiple Choice

Multiple Choice

What does NOT drive the ocean conveyor belt (thermohaline circulation)?

• temperature

• salinity

• coriolis effect

• Oceans distribute heat to the poles causing melting of the ice caps, thus influencing climate changedd

Multiple Choice

Multiple Choice

Cold ocean currents generally come from

• The North Pole 

• The South Pole

• The Equator

• Both A and B

Multiple Choice

Ocean currents have an affect on which two things

• climate and weather

• temperature and density

• land and sea

• equator and poles

Multiple Choice

Heat absorbed by the ocean is moved from one place to another, but it doesn’t disappear. The heat energy eventually re-enters the rest of the Earth system. What other key indicators of climate change are affected by the warming oceans?

• By melting ice shelves, evaporating water, or directly reheating the atmosphere.

• By creating larger waves with more heat energy that will increase erosion

• By increasing methane into the atmosphere

• By decreasing the amount of carbon diffused into the ocean

Multiple Choice

What is the importance of the ocean conveyor belt to global climate?

• It helps to cool temperatures in the tropics

• It keeps surface water cool

• It moderates the world climate by redistributing heat from the tropic

• It moderates the world climate by moving water through ocean currents

Multiple Choice

Oceans can have a significant influence on climates around the globe. Which of the following does not accurately describe this influence?

• Oceans moderate coastal climates by absorbing heat from the atmosphere.

• Oceans moderate climates by transporting heat from the tropics to higher latitudes.

• Oceans change precipitation patterns by absorbing excess water vapor from the atmosphere

• Oceans reduce concentrations of greenhouse gases by absorbing carbon dioxide from the atmosphere

Multiple Choice

Surface ocean currents flow clockwise in the Northern Hemisphere and counter clockwise in the Southern Hemisphere. What can be inferred about the effects from these surface currents on the climates at the same latitude (40 degrees N) on the east and west coast of North America?

• They will both be cool.

• They will both be warm.

• It will be cool on the west coast and warm on the east coast.

• it will be warm on the west coast and cool on the east coast

Multiple Choice

Our oceans play a large role in climate change. Which is a specific role played by the oceans in regards to climate?

• Oceans moderate the climates of the world by moving water through currents.

• Oceans create cool temperatures in the tropics by transporting cool water from the poles.

• Oceans absorb carbon dioxide, a major greenhouse gas, contributing to climate change.
