It might be called an Occum's razor … WebDec 19, 2024 · The Earth is made of three layers: the crust, mantle and core. The brittle crust and uppermost mantle are together called the lithosphere. Beneath the lithosphere, the mantle is solid rock that can flow, or behave plastically. The hot core warms the base of the mantle, which cause mantle convection.

Is the crust a convection? - Answers

WebConvection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere. The … WebApr 23, 2024 · How Convection Works Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. dakota plains federal credit union lemmon sd

WebSep 2, 2024 · Convection currents within the mantle provide one potential driving force for plate movement. The plastic movement of the mantle material moves like the flow of mountain glaciers, carrying the lithospheric plates along as the convection movement in the mantle moves the asthenosphere. Web• Convection currents: Movement caused by the gain and loss of heat energy. In the Earth’s mantle, the mantle closest to the core gains heat energy and becomes less dense than the surrounding cooler mantle. As it becomes less dense, it rises towards the crust. As it reaches the crust, the mantle cools and WebJul 29, 2012 · The interesting question is how the much slower flow in the solid mantle influences the heat flow and its spatial distribution at the core-mantle boundary, and how this will affect the Earth's ... biotics caprin

"WebThe mantle’s convective motions break the lithosphere into plates and move them around the surface of the planet. These plates may move away from, move by, or collide with each other. This process forms ocean basins, shifts continents, and pushes up mountains. 1. convection drag - the idea that when magma moves to the surface, where the … " - How does mantle convection affect the crust

How does mantle convection affect the crust

WebThe mantle allows the crust to move and also, in a way, drives the motion of the tectonic plates. The mantle is more or less solid rock, but the high temperatures (>1000°C / 1832°F) and forces present far below Earth's surface can deform the mantle, albeit slowly. The mechanism for motion of tectonic plates is still an open question. WebFrom the geothermal gradient it is also obvious that the outer core/mantle boundary is a big insulater. Since these two are separate heat transfer from the outer core to the mantle is also mainly by conduction. For the mantle it is a story of both convection and conduction. I dont think the final answer is known here. As an extra note.
