tem N sample standard deviation / D. RATES 1. Our current best estimate is that the western Grand Canyon in Anton began to be wwwvated by ever trosien about 6 million years ago. The greatest depth of the Grand Caryn is about 1.6 km. .. What is the mean (average rate that the Grand Canyon has been wroded into the Colorado Palau during the past 6 million years, expressed in millimeter per yearl Show your work below. beration of the Grand Canyon proceeded at that rate during the most recent century, how much deeper is it today than it was on the day you were bom? Show your work. 2. During Earth’s very early history, our planet was whacked by meteorites large and small and eventually grew to its current size. Earth probably went through a period in which it war molten from near the surface to its center. Throughout its history. Earth has been hotter at its center than at its outer surface a. In caves just below Earth’s ground surface in continental crust, the temperature tends to be a constant -15°C (-99*F). That’s why people use caves for wine storage. The deepest mine on Earth is currently the Mponeg gold mine just southwest of Johannesburg, South Africa, which reaches just over 4 km below the surface. At the bottom of that mine, the rock temperature reaches 66°C (151°F). Using the cave temperature to represent the surface temperature of the crustat -0 km depth, what is the rate at which temperature changes in Earth between 0 and 4 km–the near surface geothermal gradient? “C/km b. The temperature at the bottom of the lithosphere in Earth is often inferred to be around 1300°C. If we assume a depth to the base of the lithosphere of 100 km, what is a reasonable estimate for the geothermal gradient between 0 km and -100 km? *C/km c. The center of Earth at an average depth of 6371 km below the surface has a temperature that has been estimated to be approximately 6000ºC. What is the average geothermal gradient from Earth’s surface to its center? *C/km d. Write a brief statement of a hypothesis you think might best explain the variation in the geothermal gradient within Earth. .com/private manifestim.content/543533…SSTA&Signature opCOLTOOXA SKOZIT94%3D&Expires=1611769412 Page 2 of 2
