Web5 aug. 2024 · Whether or not a bit of rock counts as part of the asthenosphere is decided by its temperature. To count as part of the asthenosphere, the rocks' temperature has to have reached at least 1300°C. 3) The asthenosphere was discovered and named by a British geologist (a scientist who studies rocks) called Joseph Barrell in 1914. WebThe temperature at the earth's surface is near 0º C (freezing temperature of water). The temperature increases rapidly to about 1500º C at 100 km depth. From a depth of 100 km to about 2800 km, the temperature increases slowly by only 30º C per 100 km to a temperature of about 2500º C.
