Earth cutaway from core to exosphere Geothermal drill machine in Wisconsin, USA. Temperature within Earth increases with depth. Highly viscous or partially molten rock at temperatures between 650 and 1,200 °C (1,200 and 2,200 °F) 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 ...
The temperature of the inner core can be estimated from the melting temperature of impure iron at the pressure which iron is under at the boundary of the inner core (about 330 GPa). From these considerations, in 2002, D. Alfè and others estimated its temperature as between 5,400 K (5,100 °C; 9,300 °F) and 5,700 K (5,400 °C; 9,800 °F). [ 5 ]
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 19% of Earth's radius [0.7% of volume] or 70% of the Moon's radius. [32] [33] The inner core was discovered in 1936 by Inge Lehmann and is generally composed primarily of iron and some ...
Core temperature, also called core body temperature, is the operating temperature of an organism, specifically in deep structures of the body such as the liver, in comparison to temperatures of peripheral tissues. Core temperature is normally maintained within a narrow range so that essential enzymatic reactions can occur. Significant core ...
The potential temperature of the mantle is estimated to be about 1350 C today. There is an analogous potential temperature of the core but since there are no samples from the core its present-day temperature relies on extrapolating the temperature along an adiabat from the inner core boundary, where the iron solidus is somewhat constrained.
134 K, highest-temperature superconductor at ambient pressure, mercury barium calcium copper oxide; 165 K, glass point of supercooled water; 184.0 K (–89.2 °C), coldest air recorded on Earth; 192 K, Debye temperature of ice; 273.15 K (0 °C), melting point of bound water; 273.16 K (0.01 °C), temperature of triple point of water; c. 293 K ...
Hence, a comfortable temperature in a heated building may be 18 - 22 degrees Celsius (64.4 - 71.6 degrees Fahrenheit). [ 6 ] [ 7 ] Humans produce an obligatory 100 W (0.13 hp) of heat energy at rest as a by-product from basic processes like pumping blood, digesting, breathing, biochemical synthesis and catabolism etc.
The Earth core's heat flow—heat leaving the core and flowing into the overlying mantle—is thought to be due to primordial heat, and is estimated at 5–15 TW. [23] Estimates of mantle primordial heat loss range between 7 and 15 TW, which is calculated as the remainder of heat after removal of core heat flow and bulk-Earth radiogenic heat ...
