Do we gain any warmth from the earths core.?

Question

The earths core being very warm, do the ocean's or the mantle receive any conductive heat from it, and if so, is it slowley getting colder. Could the human race survive with a cold core.

Answer 1

The hard lithosphere does not conduct heat to the surface except in areas where it is extremely thin - such as at plate boundries or at geothermal "hot-spots" like hawaii and yellowstone. This is proven by the fact that at one time the earth was totally molten, and it has COOLED enough for the outer layers of the planet to harden into a crust.

BUT - with a cold core we would not have a magnetic sphere surrounding the planet and solar radiation would make it impossible for life as we know it to exist on the surface (although it could probably survive deep in the ocean and underground).

A side note: The reason that you can send pipes down to heat/cool your house is because this shallow part of the crust maintains a fairly constant temperature, but it is not because it is warmed by the inner-earth. It is warmed by the sun, but its temperature just changes very slowly compared to the surface because earth is a good insulator. The same parts that are warmer in the winter are cooler in the summer.

Answer 2

we do get some warmth from the earth's core but if for any reason the earth's core became cold we wont die because we get the main heat from the sun but the core will never be cold for many many resasons and the main reason is that there is not even a iny open in the earth that might pass any cool air to the core and if there an tiny open it will affect the air with the core heat not the core with the cool heat. hope i helped.

Answer 3

The core certainly convects heat to the surface though it is a very slow process. The mantle also has heat from the original accumulation process and from disintegration of radioactive isotopes. In a few billion years when our core cools enough and becomes solid, we will lose our magnetosphere which protects us from most of the solar winds. Without that protection, the planet's atmosphere should begin to be degraded and "blown away" by the solar winds.

Answer 4

A cold core wouldn't convect. Therefore we would lose the magnetic field that protects the earth from EM from the sun. Scientists think that's what happened to Mars. We would end up a dead planet.

Answer 5

yes of course we receive heat from the core. that is why the ground is always warmer and it gets colder the higher up in the atmosphere you go. we could not survive with a "cold" core.

Answer 6

no, the hard layers stop it, but their are some places where theirs water that gets heating by teh earth's core and is warm. those places are places where the waters closer to the core then the actual solid ground. the sun gives us warmth. : )

Answer 7

physique warmth no longer temperature, rigidity on the element. In some sexual arousal etc. there's a commencing off at coccyx element & cerebral fluid would leak. Feeling of uncomplicated air bypass at this element.

Answer 8

I think that geothermic heating utilizes this.
You sink rods into the ground to power underfloor heating.

Answer 9

Not unless the sun alone could warm the entire planet effectively.

Answer 10

Yes! Think Yellowstone Park!

Last question, probably not.
