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 ...
A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with a high gradient of distinct temperature differences associated with depth.
The heat (or cold) storage medium is the water and the substrate it occupies. Germany's Reichstag building has been both heated and cooled since 1999 with ATES stores, in two aquifers at different depths. [9] In the Netherlands there are well over 1,000 ATES systems, which are now a standard construction option. [10] [11]
A bathythermograph. The bathythermograph, or BT, also known as the Mechanical Bathythermograph, or MBT; [1] is a device that holds a temperature sensor and a transducer to detect changes in water temperature versus depth down to a depth of approximately 285 meters (935 feet).

The geologic temperature record are changes in Earth's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time.
Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of 150 °C (300 °F), and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation.

Judging from the descriptions the TPRC has put the wrong labels on their bricks, and if that is the case then Brick #1 is "Common Brick" and Brick #2 is "Red Brick." Tadokoro, Y., Science Repts. Tohoku Imp. Univ., 10, 339–410, 1921, TPRC pages 493 & 1169. [32] Bronze: 26 [36] 42 [51]-50 [35] [51] 293 [35]-296 [51] 5,882,000 [51] - 7,143,000 ...
