A fresh stool sample is cultured to identify the cause of diarrhea and disease carriers. Most common pathogens, such as Salmonella species, Shigella, and E coli 0.157, can be grown on standard media. Yersinia and Campylobacter require a special culture medium.
And while scientists have never sent a probe to our planetâs core to obtain accurate measurements, various estimates have been made. For instance, it is believed that the temperature of the Earthâs inner core is as high as 7000 Â°C, whereas the outer core is thought to be between 4000 and 6000 Â°C. Meanwhile, the mantle, the region that lies just below the Earthâs outer crust, is estimated to be around 870 Â°C.
The earth's core is divided into two separate regions: the liquid outer core and the solid inner core, with the transition between the two lying at a depth of 5,156 kilometers (3,204 miles).here are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.
