WebThese convection currents cause the plates to slowly move about like crackers on a bowl of boiling soup. One plate may slide past or override another, or rising volcanic material may push the plates apart at mid-ocean ridges. You need to upgrade your Flash Player WebJan 15, 2001 · This sort of magma production is called spreading center volcanism. At the point where two plates collide, one plate may be pushed under the other plate, so that it sinks into the mantle.

WebConvection Currents. The Earth's mantle has convection currents because the heat of the core acts similarly to the light bulb in our lava lamp. The core's heat energy is transferred to the mantle, causing it to rise … WebApr 9, 2010 · This semisolid magma continues to move upwards through the crust, experiences less pressure and so becomes more fluid. The result is the lava we see erupting from active volcanoes. Getting through the crust. The superheated molten rock in the mantle doesn’t normally make it through the many kilometres of crust that forms the …

WebJan 30, 2004 · In addition to this plate-scale flow, plumes of hot material can rise at various places from within the convecting mantle to form ocean island volcanoes or “hotspots” such as Hawaii. Indeed, convection currents in the mantle are responsible for most of the volcanic and tectonic processes that we see at Earth’s surface.
