Question
10. Mt. Peale is a 12,600' Peak in the La Sal Mountains of southeast Utah. Several watercourses develop on the flanks of Mt. Peale before heading generally to the west towards the Colorado River in the Canyonlands. Stream A rises on the NW side of the mountain and the segment measured falls by 5,050 feet over a map distance of 16,896 feet. Stream B rises on the SW side of the mountain and the segment measured has an upper elevation of 10, 234 feet and a lower elevation of 4608 feet. The map distance between these two elevations is 5.8 miles. (4) A. What is the gradient of Stream A? B. What is the gradient of Stream 8? Report the slopeof Stream Aas the percent slope. Which stream is likely to be the higher order one? c. D. 11. Given: A topographic map with a scale of 1:10,000 and a topographic profile with a vertical horizontal scale exaggeration of 25x, determine the vertical scale used for the profile (VE vertical scale). (ANSWER EITHER 12 OR 13. Answering both will result in my grading Problem 1) 12. Metamorphic Facies Diagram (below). (A) What is the pressure and temperature at the point where Andalusite, Kyanite, and Sillimanite coexist as three phases? (B) What is the pressure range for Andalusite? (C) What is the temperature range for Andalusite? (D) At 300P C, how much would the pressure have to drop for Eclogite to transform into Prehnite-Pumpellyite? (2) 14 12 10 Eclogte Blueschist 2. 100 200 300 400 5006000 800 900 Temperature CExplanation / Answer
10) A. gradient of stream A is = 0.298
Gradient = 5050 / 16896 = 0.298
B. gradient of stream B is = 0.184
10234 - 4608 = 5626 feet, 5.8 mile = 30624 feet, So, gradient = 5626 / 30624 = 0.184.
C. Slope of stream A as percentage slope is = 29.8
D. Strem A is likely to be higher order.
11) Topographic map with scale 1 : 10,000
1cm in map scale is equal to 100m in real world.
vertical exaggeration is = 25x
VE = horizontal scale / vertical scale
vertical scale = horizontal scale / VE = 10,000 / 25 = 400
So, here the vertical scale is 1 : 400.
12) A. Pressure is greater than 3kb but less than 4kb, and temperature is ~500oC.
B. Pressure range for andalusite is 0 to less than 4kb.
C. Temperature range for andalusite is 200 to 750oC.
D. ~3kb pressure have to drop.
