Geological Survey , the magnetic field protecting Earth is generated by the electric currents caused by the convection currents or heat transfer of molten iron in the outer core.
More than 80 years on, she finally discovered that the stripes control body temperature by creating convection currents as heat is lost from the skin.
considering the role of heat energy and convection currents in the movement of tectonic plates; and
It was assumed by scientists like Mick Pearce that termite mounds regulate temperature through a system of convection currents. A convection current is created when less dense, warm air rises and more dense, cool air sinks.
Exactly what mechanism or mechanisms are behind their movement is still debated, but are likely to include convection currents within the asthenosphere and the forces generated at the boundaries between plates.
can hay but it "The gusts can lift deposited pollen from surfaces and the downdraughts can bring pollen down from higher levels in the air where it has been lifted by convection currents," said Dr Emberlin.
The prevailing theory holds the trouble occurs around tropical storms in which strong convection currents move moist air from low altitudes to high altitudes where the local temperatures are very cold, creating high concentrations of ice crystals.
Vents and/or exhaustion systems are istalled on the warehouse roofs aiming to equalize the silo in ternal pressure during the loading/unloaing processes, since providing the aeration air exit makes easier to re move gases originated from the stored grain ecosystem and dislocating the hot air acculated in the warehouse upper part through the convection currents. There fore, the possibility of water vapor concentrated in the warehouse ceiling, the oxidtion of metallic structures, the grain germination, the proliferation of plagues and safety risks are reduced (JIAN & JAYAS, 2012).
Convection currents will be much weaker, reducing cooling effects and giving problems with cooking, ventilation and more.
It is my best guess that this venting system was a way to actively force the convection currents in the rooms to allow them to be more comfortable." Seabold plans on reinstating this energy-saving system.
The patented design employs convection currents rather than active pumping in the most corrosive and radioactive part of the reactor, thus eliminating materials challenges within other designs.
