M INE2200 - Wint er 201 9 Lab 6 - Plate Tectonics pg. 1 / 9 pts Name: B00: Name: B00: Your total= / 4 4 PLATE TECTONICS EXERCISE 6 . 1 Sources of Heat for Earth Processes o Some of the heat that affects geologic processes comes from the Sun and some comes from inside the Earth. Each one of these heat sources play a role in Earth processes . o In the upper 10 km of the crust, the geothermal gradient is typically about 25°C per km, but can range from 15°C/km to 50°C/km. In the diagram below, plot these three geothermal gradients for the upper 10 km of the Earth. .. ...... .......................... ............................................................................................ . ..( 6 pts ) o The deepest mine on Earth (TauTona in Carletonville, South Africa) penetrates to a depth of about 3 895 m . Using the geothermal gradients, you just drew, what range of temperatures would you expect in the mine ? .. ... ............................................................................................................................. ...... .... ..( 3 pts )
