WebConvection currents also stress the lithosphere above, and the cracking that often results manifests as earthquakes. According to. asthenosphere, zone of Earth’s mantle lying beneath the lithosphere and believed to be … WebConvection The movement of warm and cool air creates a convection current. Birds, like this soaring bald eagle, use convection currents to rise and fall with very little effort. So do gliders which are aeroplanes without engines. An aeroplane tows a glider up into the sky.

As the current descends, it gradually moves from the northeast to the southwest, back toward the Equator. The consistently circulating patterns of these air masses are known as trade winds.

WebConvection is the exchange of heat energy by the development of a liquid (fluid or gas) between regions of various temperatures. Warm air is less thick than cold air, thus convection flows are created within the sight of a temperature angle. WebConvection Currents The heat from the core causes the mantle to be heated at its base. The hot rock rises gradually towards the crust. As it rises, it moves further away from its heat source at the core and starts to cool down. When it reaches the crust, it is forced out sideways because it cannot easily pass through the solid rock above it.
