Bitesize convection currents
WebThe denser cold liquid or gas falls into the warm areas. In this way, convection currents that transfer heat from place to place are set up. Convection currents can be seen in lava lamps. The wax inside the lamp warms up, becomes less dense than the liquid and so rises. When it rises, it cools and becomes denser again, so it sinks. 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 …

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 … WebSep 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. Seafloor spreading occurs at divergent plate boundaries.
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. WebAug 8, 2024 · Convection facts for kids. Convection is the movement of heat because of the movement of warm matter. For example, atmospheric circulation moves warm air to cool places, causing wind. Wind, in turn, …
