How does the greenhouse effect work and what does it have to do with climate change?

greenhouse gases absorb IR radiation and keep some in atmosphere which keeps atmospheric temp stable as long as gas amounts remain
stable.
the gases make things colder
it doesnt have to do with climate

what are deep ocean currents, how do they affect Earth and how are they formed?

they are driven by density and temp gradients and formed by differences in water temperature and density. They're called submarine rives and flow under ocean...
they are caused by heat
they don't exist

what way do gyres and air flows go in the N. Hemisphere compared to S. Hemisphere?

In N. Hemisphere things move clockwise while S. Hemisphere has counterclockwise movement.
In N. Hemisphere things move counterclockwise while S. Hemisphere has clockwise movement.
In N. Hemisphere things move clockwise and in S. Hemisphere there is clockwise movement.

What is the Coriolis Effect?

It causes surface currents to turn and twist into semicircular whirls called gyres.
It causes deep ocean currents to turn and twist into whirlpools.
It causes surface currents to cause tornados.
