WebAug 3, 2024 · Thirty miles up (about 50 kilometers), temperatures range from 86 to 158 Fahrenheit (30 to 70 Celsius), a range that, even at its higher-end, could accommodate Earthly life, such as “extremophile” microbes. And atmospheric pressure at that height is similar to what we find on Earth’s surface. WebLithosphere: The lithosphere is the outermost layer of the Earth that consists of the entire crust and the top-most portion of the mantle.; The average thickness is ~70km, but ranges widely: It can be very thin, only a few km thick under oceanic crust or mid-ocean ridges, or very thick, 150+ km under continental crust, particularly mountain belts.; Depth- 0-100 km computing one sided limits
