S ustainable E nergy S cience and E ngineering C enter Plate Tectonics Source: http://geothermal.marin.org/GEOpresentation Earth's crust is broken into huge plates that move apart or push together at about the rate our fingernails grow. Convection of semi-molten rock in the upper mantle helps drive plate tectonics.

S ustainable E nergy S cience and E ngineering C enter Source: http://geothermal.marin.org/GEOpresentation New crust forms along mid-ocean spreading centers and continental rift zones. When plates meet, one can slide beneath another. Plumes of magma rise from the edges of sinking plates. Plate Tectonics

S ustainable E nergy S cience and E ngineering C enter Magma Source: http://geothermal.marin.org/GEOpresentation Thinned or fractured crust allows magma to rise to the surface as lava. Most magma doesn't reach the surface but heats large regions of underground rock.

S ustainable E nergy S cience and E ngineering C enter Geothermal Reservoir Source: http://geothermal.marin.org/GEOpresentation When the rising hot water and steam is trapped in permeable and porous rocks under a layer of impermeable rock, it can form a geothermal reservoir. Geothermal reservoirs can reach temperatures of 370 o C.

S ustainable E nergy S cience and E ngineering C enter Geothermal Plant Source: http://geothermal.marin.org/GEOpresentation Natural steam from the production wells power the turbine generator. The steam is condensed by evaporation in the cooling tower and pumped down an injection well to sustain production.
