WebConvection currents are present everywhere, from the atmosphere to magma within the plates. The basic principle of a convection current is that warm air rises because of the extra energy it received in the form of heat … WebConvection currents enable hot air balloons to rise, and also explain why it is often hotter in houses upstairs rather than downstairs. Most of our winds are caused by convection …

WebSome 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 … Webgenerated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart.. Where convection currents converge, plates move towards each other.. The movement of the plates, and the activity inside the Earth, is called plate tectonics.
WebApr 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. WebConvection is a way in which heat travels. It occurs when heat is transferred by the movement of liquids or gases. The other methods of heat transfer are conduction and radiation.

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. gptx trash pickupWebSep 27, 2024 · The currents descend back toward the ground at about 30° north latitude. 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.
