real input please. PLLEASEEEEEE HELPP!! need it for homework!?

Question

I need a good answer, not what you THINK, something fact-like.
-->what do you think happens to the majority of water (not ice) at the poles?
-->what do you think happens to the majority of water at the equator?
-->what two characteristics of water combine to form a thermohaline current?

Answer 1

The majority of water near the poles sinks, Much also freezes some evaporates(sublimes). Majority of water at the equator rises and evaporates. 2 characteristics of water that combine to form a thermohaline current are density and specific heat. More salt dissolves in warmer water.

Answer 2

Giving you the answers is not as valuable as giving you the reasons.


Why does a hot air balloon rise? Because the air in the baloon expands when heated. It occupies more space, so each cubic foot weighs less than a cubic foot of cold air. Since it weighs less, it wants to rise.

Air over a hot surface rises, for the same reason.

Water, too, expands when heated. Warm water will rise above cold water.

When water freezes, it expands, so ice is lighter than water.

Ice is a pretty good insulator, so water at the poles is likely to be pretty much at the same temperature from top to bottom. Not likely to be much up and down movement.

Water molecules are always bouncing around. When they are at the surface, some escape into the air. This of course, we call evaporation. It is why clothes get dry, and why it is likely to be humid at the beach.

Water is also what we call fluid. Something can push its way through a fluid.

Salt water is heavier than fresh water, and the more salt, the heavier.

When saltwater evaporates, the salt stays behind. The surface water is then heavier than the water just below. So what happens?

Now you should be able to answer the questions. If not, ask some more.

Answer 3

The thermohaline circulation (THC) is a term for the global density-driven circulation of the oceans. Derivation is from thermo- for heat and -haline for salt, which together determine the density of sea water.

Answer 4

2nd Question is that it evaporates or it becomes ground water.
