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 ...

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 crust of volcanically active Venus could be churning with convection currents just like the Earth's mantle. This is the conclusion of researchers from the Washington University in St. Louis, who ...

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 ...

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 ...

Sara is freezing so she asks her handy science app, Ada, for help. Ada explains the process of conduction, convection and radiation. Ada takes Sara through various scenarios, discussing how she could ...

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 ...
