Introduction
Why do you think climate change will impact developing nations the most?

areas, and species and natural areas?

area?

What is the ITCZ?
Why does the ITCZ vary with the seasons?

Explain the Coriolis Effect or why things are deflected to the right in the Northern
Hemisphere and to the left in the Southern Hemisphere.
Cold water currents are usually found on this side of the oceans (eastern or western?
Warm water currents are usually found on this side of the oceans (eastern or western?
How do surface currents help regulate our climate? Can you give an example?
Which current run along the margin of California?
What is Ekman transport?
How does Ekman transport influence upwelling and downwelling?
Regarding El Nino; (ANSWER T OR F)
1. Warm water moves across the Pacific and piles up on the western margin of S &
N. America
2. The thermocline is shallower
3. Upwelling increases
4. The atmospheric circulation completely reversed to form one circulation cell
moving air in the opposite direction.
5. The trade winds are stronger
6. El Nino impacts on fishing, droughts, corals, disease are only in the Pacific
Region
7. Less disease is associated with El Nino in Peru
8. In Peru, upwelling stops and the fishing industry collapses during El Nino.
How does the Pacific Decadal Oscillation differ from El Nino?
Heat & Currents
Why is it warmer at the poles than at the equator?
What happens to solar radiation as it enters the atmosphere? (How much is reflected,
absorbed, etc)
Heat is transferred to the poles through these two processes.
What is salinity?
Is organic matter a salt?
In 1000 grams of seawater, how many of those grams are salts?
These are the two most abundant salts.
Where did the cations and anions that form the salts come from?
Why does ice float?
Do salinities increase or decrease in regions of the oceans where ice is forming?
Which two factors control the salinity of ocean water? Explain.
How does salinity vary with latitude (e.g. 0 degrees latitude, 10-40 degrees latitude, 6090 degrees latitude)?
Explain in detail why the oceans are stratified and how thermohaline circulation
develops.
Towards the polar region the salinity of the ocean water is less than that of waters in
areas of the middle waters. Yet the polar waters are denser. Why?
Why is the Pacific Ocean not as well stratified as the Atlantic?
Refer to the slide about the Atlantic and Deep Water Circulation. Explain the connection
between surface currents and deep ocean currents?
How does the connection between surface and deep ocean currents impact the climate?
What is the thermocline?
What is the halocline?
