What Are Convection Currents? - Science Trends

WebThe convection currents happen down in the mantle. Our continents and plates are dragged along on top as the mantle stuff moves underneath. When two plates rub against each other there is an earthquake. When one plate gets pulled under another bits of it melt and push their way back to the surface - that's a volcano.

WebOct 30, 2024 · Convection currents within the magma drive plate tectonics. Heat produced through the radioactive decomposition of elements buried in the interior of the Earth results in magma (molten rock) in the aesthenosphere. The aesthenosphere (70km to 250 km) is the mantle's part, the central sphere of the Earth that stretches up to 2900 km. Answer 3: WebThe mesosphere works basically the same way. It provide a solid barrier so that the iron cannot go up, so the iron is basically confined to the layer of the earth it inhabits. Yes, the fluid in the core is extremely densely packed. The sheer pressure there compresses the iron atoms extremely close together. cvjećarna diva ogulinWebThe force that moves the plates is thought to be convection currents in the mantle under the Earth’s crust. The mantle is solid in the short term, but flows very slowly over geologic timescales. dji icon
