Earth’s Interior Is Cooling “Much Faster Than Expected”


Recommended Posts

So, it's cooler on the inside and warmer on the outside?

Quote: "The evolution of our Earth is the story of its cooling: 4.5 billion years ago, extreme temperatures prevailed on the surface of the young Earth, and it was covered by a deep ocean of magma. Over millions of years, the planet’s surface cooled to form a brittle crust. However, the enormous thermal energy emanating from the Earth’s interior set dynamic processes in motion, such as mantle convection, plate tectonics, and volcanism.
Still unanswered, though, are the questions of how fast the Earth cooled and how long it might take for this ongoing cooling to bring the aforementioned heat-driven processes to a halt.
One possible answer may lie in the thermal conductivity of the minerals that form the boundary between the Earth’s core and mantle.

A little bit of the inside cooled down the other day when that volcano blew in Tonga….there’s always a heat transfer from the inside to the outside when that happens….lots of variables involved in global warming/cooling….. last time I checked, NASA was saying that the major contributor to the shrinking polar icecap in Antarctica was geologic (volcanic) vs. anthropogenic.

I wish I could find the old link I read… but thanks for the good read….
