Convection currents are found in which layer
WebSep 2, 2024 · Convection Currents in the Mantle. Heat in the mantle comes from the Earth's molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending tectonic plates. The heat in the outer core results from residual energy from the Earth's formative events and the energy generated by decaying radioactive elements.

WebThe 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. WebAboutTranscript. There are three forms of thermal energy transfer: conduction, convection, and radiation. Conduction involves molecules transferring kinetic energy to one another through collisions. Convection occurs when hot air rises, allowing cooler air to come in and be heated. Thermal radiation happens when accelerated charged particles ...
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. WebThe Earth's outer core is in a state of turbulent convection as the result of radioactive heating and chemical differentiation. This sets up a process that is a bit like a naturally occurring electrical generator, where the …
