There's a small problem with Earth's magnetic field: It should not have existed, as Earth's rock record indicates it has, for the past 3.5 billion years. Motions in the Earth's molten iron core ...

Radioactive potassium, common enough on Earth to make potassium-rich bananas one of the “hottest” foods around, appears also to be a substantial source of heat in the Earth’s core, according to recent ...

Findings from a table-top experiment have revealed that the primary driver of a type of fluid flow called solutal convection has been overlooked. What's more, once this driver is accounted for, it ...

Sound waves have been used in the lab to mimic the role that gravity plays in driving convection in huge rotating bodies such as stars and planets. The new experiment was created by Seth Putterman and ...

Heat can be transferred from one place to another by convection in liquids and gases (fluids). A beaker is heated and the coloured fluid inside shows convection currents This is because the particles ...
