and rise to the top of the room. This forces down the cooler air so that it becomes heated, thus creating a convection current. Thermal radiation generates from the emission of electromagnetic waves.

Convection currents can be seen in lava lamps.The wax ... radiators actually transfer most of their heat to a room by convection, not radiation (see Convection above). So, radiators are the ...

One explanation may be convection currents, or the lack of them. The room’s thermostat is likely to be positioned roughly midway between floor and ceiling. On a 20°C day in the summer ...

In this activity from Lawrence Hall of Science, you’ll use hot and cold water to see how fluids at different temperatures move around in convection currents. Be sure to share what you’ve learned about ...

Directly below the lithosphere is the inner mantle known as the aesthenosphere. Convection currents are generated in the earth’s inner mantle as molten rock forms from the radioactive decay of ...
