convection currents in the mantle
convection currents in the mantle
The plates move in response to the slow convection currents in the mantle.
Convection Currents. The mantle
Mantle CONVECTION. Convection occurs because the density of a fluid is
Convection currents in the crust, known as the lithosphere
Inside the mantle, convection currents rise slowly, fueled by heat in the
Convection currents within the mantle
Various convection current systems proposed for tectonic movement.
The food coloring moves through the water as a result of convection currents
These convection currents are created by heat from within the earth - much
(mantle plumes, subduction zones, midocean ridges, convection currents,
ride on the asthenosphere, which flows due to convection currents.
The mantle is a hotbed of unrest, with swirling convection currents
the upper mantle towards
The Mantle
This creates a slow vertical current in the mantle.
Note the assumed mantle convection. When a fluid is heated from beneath,
The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of
the convection currents in the mantle moves the plates of the Earth.
The movement of the plates is driven by convection currents in the mantle.
