The process where incoming solar radiation of relatively short wavelength is absorbed by the earth and reradiated as longer wavelength, infrared radiation, which is absorbed by the earth's atmosphere. The net result being an increase in the earth's surface temperature. Greenhouse Effect Top of Page Heat Flow Dissipation of the earth's internal energy by conduction and radiation at the surface. Hot-dry Rock A method of developing geothermal energy where two wells are drilled in an area with a high geothermal gradient. The rocks are fractured between the two wells.
Cold water is pumped down one well and hot water is pumped up the other well.
A natural spring who's water has an anomalously high temperature that is associated with a hydrothermal system. Hydrothermal System Hydrocarbon A compound composed of carbon and hydrogen atoms that was derived from organic matter. Requirements for the development of hydrothermal systems include, a heat source, permeable rocks, the presence of water and a cap rock. The process of converting loose, unconsolidated sediment into a solid rock. Naturally occurring gasses found in sedimentary rocks.
