Right. But the fountains themselves were cold.
Lunacy!
The fountains were superhot simply because they had constant ongoing force and mass and were not isolated geysers like Old Faithful.
Atom bomb mushrooms clouds are hot!
A little science for you:
"A mushroom cloud forms when an explosion creates a very hot bubble of gas. The hot air is buoyant, so it quickly rises and expands. The rising cloud creates a powerful updraft which picks up dust, forming the stem of the mushroom cloud.
"The fireball from an H-bomb rises so high that it hits the tropopause, the boundary between the troposphere and the stratosphere. There is a strong temperature gradient at the tropopause, which prevents the two layers of the atmosphere from mixing much. The hot bubble of the fireball initially expands and rises. By the time the bubble has risen from sea level to the tropopause, it is no longer hot enough to break through the boundary.The same thing happens to big summer thundercloud when they rise up to the tropopause, producing a characteristic flattened-anvil shape.
So according to Dividers thunder clouds are too cool to climb with their load of moisture? Quote: They grow vertically instead of horizontally, forming into dense towers that can reach 20,000 feet, though they've also been known to go as
high as 75,000 feet! Fancy cold water climbing that high!
The updraughts of the water jets picked up dust, water and organic matter - which is what is found in asteroids, comets ...
Perhaps I ought to give you some real science THAT IS SO FAR ABOVE YOUR UNDERSTANDING THAT YOU WILL SNEER LIKE A FOOL? But as Schopenhauer wrote:
All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as self-evident.
Here goes: Volcanoes are burning organic matter from the flood. Supercritical water can ignite organic matter - pretty much like pure oxygen can?
IN the years before the flood Earth was nice and warm courtesy of the underground heating GOD designed into it. This same underground heating is what caused the mist to rise. The poor near-autistic Greta Thunberg hasn't a clue about how this underground heating is the global warming she howls about.
As the flood started and the crust began shattering into pieces rhe supercritical water and massive jolts of electricity combined to make superfires by burning the minerals in Earth: lava is made of
the elements silicon, oxygen, aluminum,
iron, magnesium, calcium, sodium, potassium, phosphorus, and titanium (plus other elements in very small concentrations.
Have volcano like fires burst into flame under the crust and the resulting geysers woul have plenty power to blast material into outer space.
Despite what all the evolved monkeys claim volcanoes cannot be ancient outlets of molten iron from inside Earth as uncontrolled vulcanism would occur via supercritical water reacting with magma.
Let's do a little Schopenhauer math: One cubic foot of water expands to 1700 cu.ft steam. One cubic mile expands to 1700 cu.miles. One cubic mile restrained to a one mile square column would climb 1700 miles? If said cubic mile was constantly replenished how high would it rise allowing for cooling of outer edges of rising column? If the cubic mile was superhot stam and a combusting mixture of those elements in lave the column would be self sustaining as it climbed out into space to pummel the Moon with masses of debris to pockmark its front face?
