WebMantle convection is characterized by mobile plates on its top surface, which have no chance to be recovered in experiments with a rigid top boundary since the latter imposes … WebThe asthenosphere is ductile due to great pressure and temperatures. The outer core is liquid iron that circulates and moves the lithospheric plates above. Deep mantle convection moves the asthenosphere and the lithosphere above it. The asthenosphere is composed of melted rock that moves easily.
WebMay 21, 2008 · How Do Plates Move? Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It … WebSome plate models show that two thirds of the Earth’s surface move faster than the underlying mantle so there appears to be little or no evidence that convection currents in …
