In physics, thermal convection of a fluid is exhibited by the appearance of geometric structures through which the fluid moves, forming closed circuits. This phenomenon is of vital importance for many ...

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 ...

A study proposes that imbalanced forces and torques in the Earth-moon-sun system drive circulation of the whole mantle. The new analysis provides an alternative to the hypothesis that the movement of ...

Convection is the flow of heat energy from a region of high temperature to a region of low temperature by movement of a fluid. Convection only occurs in fluids (liquids and gases). Convection in a ...

THE recent spell of hot sunny weather in England made possible a series of experiments concerning the existence and magnitude of thermal convection currents in the air, arising from the reflection of ...

Ocean currents, the atmosphere of Venus, the surface of the sun and a bowl of miso soup all have one thing in common: They convect. Here's how to check that out. More home experiments » Clock the ...

IT has become clear in recent years that there is a formidable case for continental drift. The most convincing single piece of evidence comes from palæomagnetism 1, but this is amply supported by a ...
