How do geophysicists determine whether the mantle convects heat from the molten-iron core to the surface crust, rather than conducting heat through motionless rock?
The water coming out of the vent is very hot but nearby it's quite cold, because water is not a good conductor of heat and the heated water from the vent convects upwards, drawing cold water in from the environment.
There is also a lot of evidence regarding how the outer core of the Earth convects and that helps to establish the temperature.
Because the air above 6 feet is not mixed, about half the heat gain from people and nearly all the lighting gain is convected out of the space before it causes a temperature gain in the occupied zone.
The fin frame allows the motor to conduct and convect heat, which smoothbody motors don't do as well.
