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.
At the center of the sun, the temperature is 27 million degrees Fahrenheit (15 million degrees Celsius). As the temperature on its surface rises and falls, the sun boils and bubbles. Particles escape from the star from the sunspot regions on the surface, hurtling particles of plasma, known as solar wind, into space. It takes these winds around 40 hours to reach Earth.
