●● During the spring and fall where is solar radiation strongest?
Answer: At the equator.


●● Why does air rise at the equator?
Answer: At the equator there is more solar radiation so the air is warmer
and less dense so it rises


●● Why does air sink at the poles?
Answer: At the poles there's less solar radiation. So the air is colder and
more dense so it sinks.


●● Why is atmospheric circulation critical in moderating Earth'a
climate?
Answer: The circulation of hot air at the equator to the poles
and
cold air at the poles to the equator moderates earths climate.

, ●● Where in the world is there minimal to no layering in the ocean?
Answer: Near the poles! Where there are high latitudes.


●● Is there a positive or negative relationship between salinity and
density?
Answer: It is a positive relationship. As salinity increases density
increases.


●● How does salinity in the middle of the ocean compare the edges of
the continents?
Answer: There is lower salinity near the continent because river run offs
are adding fresh water


●● Process that deflects wind (and ocean) currents
Answer: The Coriolis Effect. It occurs because objects in the equator
rotate faster than object closest to poles.


●● What drives horizontal movement of surface currents?
Answer: Wind


●● What drives vertical flow in the ocean?
Answer: Density.
