If the Fountains of the Deep did and could shoot upwards with such force that the water went into near-space or orbit or almost into orbit, would that remove a large quantity of "heat" from the earth (and put into space) and thus cool the earth enough to have an "Ice Age?"
I think you're asking the wrong question.
If enough heat could be removed, yes, of course it could cause an Ice Age. But you might as well ask, "If the world was turned inside out...?" or "If pigs could fly...?"
The "if" is so big that it makes the rest of the question irrelevant.
You need to look at if the "fountains of the deep" scenario is possible before you can detail its consequences.

Re: kinetic energy does not necessarily convert to heat
TheLiteralist writes:
When something is propelled upwards, it stops momentarily at the peak before returning towards the earth. At this point ALL kinetic energy has been turned into potential energy....
This is where you make your mistake, if we are talking about objects in orbit.
An object in orbit, such as the space shuttle, is not just thrown "upward". It must have a "forward" velocity of around 18,000 mph to stay in orbit - i.e. it still has kinetic energy. It is that kinetic energy which must be dissipated as heat to reduce the "forward" speed from 18,000 mph to 0.

You are completely wrong about this...completely
TheLiteralist writes:
Braking DOES convert ALL kinetic energy to heat.
The point is that all of the kinetic energy has to go somewhere.
Try this experiment:
Lay an iron bar on an anvil and beat on it for a while with a hammer. What happens?
The iron bar will heat up. The anvil will heat up and the hammer will heat up. The kinetic energy from your arm swinging the hammer is converted to heat. And nothing moved.
Similarly, your idea of raindrops transferring kinetic energy to the earth and "cancelling each other out", is wrong.
Take a scenario with only two raindrops on opposite sides of the earth. Their vectors "cancel out" as you say. But they can't move the earth, since they are exerting equal forces from opposite directions. So, where does their kinetic energy go?
Heat.
Taken as a statistical population, all the raindrops of your forty-day rain will "cancel each other out" as far as movement of the earth is concerned. So, where does their kinetic energy go?
Heat.
There's no escape. All that kinetic energy has to go to heat, whether it's heating up the atmosphere by friction or heating up the earth by impact.

Re: deformation
TheLiteralist writes:
... does all the kinetic energy become heat given that there is deformation?
But we're talking about raindrops, aren't we? How much do you expect raindrops to deform the earth?
Remember also that the raindrops have already given up most of their energy to atmospheric friction before they reach the earth.
