IB ESS

How do ocean currents regulate global temperatures?

• By increasing solar radiation

• By redistributing heat from the equator to the poles

• By reducing atmospheric pressure

• By increasing precipitation in deserts

What is the role of the Hadley Cell in the tricellular model?

• It creates high-pressure zones at the poles.

• It drives air circulation near the equator.

• It regulates ocean currents.

• It reduces precipitation in temperate regions.

Which of the following INCREASES your IB ESS teacher's ecological footprint the most?

• Your teacher composts most of her biodegradable waste.

• Your teacher buys most of her produce from local farmers.

• Your teacher eats small amounts of meat about once or twice a week.

• Your teacher flies in an airplane across to the other side of the country each year.

• Your teacher's small old house doesn't have air conditioning.

Answer explanation

Flying is HORRIBLE for anyone's ecological footprint! Some companies have started programs that allow those who fly an opportunity to buy carbon offset credits to attempt to balance out their impact on climate change.
