It depends on where you are, in many places the answer is zero. NDAWN Deep soil temperatures Current Deep Soil Temperatures This page shows deep soil temperatures for those stations which are equipped with deep soil temperature probes. About 10 GW of geothermal electric capacity is installed around the world as of 2007, generating 0.3% of global electricity demand. 1998 Childrens Online Privacy Protection Act (COPPA). April 19, 2019. Nafziger, E.D. Highly viscous or partially molten rock at temperatures between 650 and 1,200C (1,200 and 2,200F) are found at the margins of tectonic plates, increasing the geothermal gradient in the vicinity, but only the outer core is postulated to exist in a molten or fluid state, and the temperature at Earth's inner core/outer core boundary, around 3,500 kilometres (2,200mi) deep, is estimated to be 5650 600 Kelvin. If the gradient of the stabilized regime is projected above this point to its intersection with present-day annual average temperature, the height of this intersection above present-day surface level gives a measure of the extent of Holocene uplift and erosion. Your question has an incorrect assumption built in. As a general rule, the crust temperature rises with depth due to the heat flow from the much hotter mantle; away from tectonic plate boundaries, temperature rises in about 25-30 C/km (72-87 F/mi) of depth near the surface in most of the world. Another important consideration is soil temperature. North Central River Forecast Center (NCRFC) Soil Temperature Network - The NCRFC operates this network of 47 stations (12 in Michigan) that collect weekly readings of soil temperature at depths of 2, 4, 8, 20, 40 and 60 in at locations throughout the north central US.

Click In most years we stay in the optimum application window for at least a couple weeks, if not longer, so you'll have some time to make applications. Values are in degrees Celsius and are updated hourly. To obtain accurate bottom hole temperature estimates, it is necessary for the well to reach stable temperature. [22] Mean heat flow is 65mW/m2 over continental crust and 101mW/m2 over oceanic crust. Embedded hyperlinks in a thesis or research paper. To put this in perspective, the maximum and minimum soil temperatures at 2-inch depth at the Michigan State University Enviroweather station in Coldwater on April 8, 2019 (the warmest soil date so far this year), were 62.4 and 50.9 F, respectively. The uppermost layers of the solid planet are at the temperature produced by the local weather, decaying to approximately the annual mean-average ground temperature (MAGT) at a shallow depth of about 10-20 metres depending on the type of ground, rock etc;[8][9][10][11][12] it is this depth which is used for many ground-source heat pumps. If you can routinely get 30 C colder than day time air temps, then you only have to store a few days worth of coolth instead of a years worth. stations. collected and stored as either discrete. Geothermal energy is derived from the natural heat of the earth.
