As crops go into bins, growers will be looking to maintain quality until their marketing opportunities improve. Some ongoing ...

The possible causes of convection in the Earth's mantle are examined, and it is concluded that radiogenic heating together with thermal conduction is most likely to provide the driving force for any ...

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 ...

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 ...

How are ocean currents caused, and how do they affect climate? These questions were hotly debated in the nineteenth century. Some argued that water is simply pushed along by the wind; others ...

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 ...

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 ...
