Does earth's mantle flow
WebJul 6, 2016 · By recording seismic waves generated by earthquakes, they were able to look deep inside the earth and create images of the mantle’s flow, similar to the way a doctor images a broken bone. Illustrations show how (a) pressure gradient-driven flow and (b) density-driven small-scale convection could work in the asthenosphere. WebJan 17, 2024 · “Heat from the base of the mantle contributes significantly to the strength of the flow of heat in the mantle and to the resultant plate tectonics.” The researchers estimate up to approximately 50 percent of plate dynamics are driven by heat from the Earth’s core and as much as 20 terawatts of heat flow between the core and the mantle.

Earth has three layers: … WebBecause it is a fluid mix of iron and nickel, currents result when the Earth rotates. This flow of conductive fluid induces electric currents, which in turn creates a magnetic field. This is the "Dynamo theory", which proposes that a "rotating, convecting, and electrically conducting fluid" can maintain a magnetic field. ( 6 votes) Jazz Falcon
WebMantle convection is the main way heat from Earth’s interior is transported to its surface, and this heat escapes principally through mid-ocean ridges. In fact, the connected mid-ocean ridge system is in essence a 80,000 km long volcano. Escaping heat along these ridges causes hot water to circulate through the crust in a “hydrothermal system.”
