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.

WebConvection: Hot air rising, cooling, and falling (convection currents) An old-fashioned radiator (creates a convection cell in a room by emitting warm air at the top and drawing in cool air at the bottom). Radiation: Heat from the sun warming your face Heat from a lightbulb Heat from a fire great wall qinWebApr 16, 2024 · What is a convection current BBC Bitesize? Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Air current close to a radiator. Heat energy is transferred from hot places to cooler places by convection. great wall quitoWebSome plate models show that two thirds of the Earth’s surface move faster than the underlying mantle so there appears to be little or no evidence that convection currents in the mantle move plates (apart maybe from some very … great wall quizWebSep 27, 2024 · Mantle convection is the slow, churning motion of Earth’s mantle. Convection currents carry heat from the lower mantle and core to the lithosphere. Convection currents also “recycle” lithospheric materials back to the mantle.
