Geography 121, Global Physical Environment Problem Set 5 Graded problem set. Please turn in to Blackboard. 1. For this problem set, there is a single problem. The problem is: calculate the wind speed and direction based on the following information. Lake Superior North wind: 20 knots East wind: 44 knots Please express the speed in miles per hour and the direction in degrees.
Geography 121, Global Physical Environment Problem Set 2 Please make sure to show all work. When you compose your assignment, make sure to retype the problem questions before starting your calculations. Work can be submitted as a Microsoft Word or PDF document (as long as appropriate work is included). Feel free to scan your work prior to sending in the assignment. 1. If the temperature outside is 10° F, calculate this temperature in degrees Celsius (° C). Please express your answer to one decimal place accuracy. 2. A meteorologist reports that a thunderstorm is producing heavy rain at the rate of 6 centimeters per hour. Calculate this rate in inches per hour. Please express your answer to one decimal place accuracy. 3. If a river is discharging at 9,000 cubic feet per second at its delta, calculate the river’s velocity if the width is 40 meters and the depth is 3.5 meters. Please express your answer using English units and to one decimal place accuracy. 4. Convert the outside air pressure to millibars. The current outside air pressure is 29.65 inches of mercury. Please express your answer to one decimal place accuracy. 5. If the outside air is holding 4.7 g/kg of water vapor and at the current temperature could hold 6.1 g/kg of water vapor, what is the relative humidity? Please express your answer to one decimal place accuracy.
Geography 121, Global Physical Environment Graded Problem Set 4 1. Light travels across space to reach Earth and “feed” plants. Sunlight travels at the speed of light, or 299,792,458 meters per second (m s-1). What is this speed in miles per hour? Also, if the round-trip distance between Key Largo, Florida, and Fairbanks, Alaska, is 9,930 miles, how many trips could be taken in one second at this rate of speed? Please express your answers to one decimal place accuracy. 2. Using the rate from Problem 1 (speed of light in miles per hour), calculate the amount of time it takes sunlight to reach Earth during early January (sun is closest to Earth at this time). Assume the distance from the sun to Earth is 91,500,000 miles. Please express your answer to one decimal place accuracy. 3. Via the food-making process of photosynthesis, plants use 200 billion tons of carbon dioxide from the atmosphere every two years. At this rate of removal, how many pounds of carbon dioxide are removed from the atmosphere every month? Please express your answer to one decimal place accuracy. 4. A very large tree in the Redwood forest of California is 400 feet tall. Calculate this height in centimeters, meters, inches, yards, and rods (one rod is equivalent to 16.5 feet). Please express all answers to one decimal place accuracy. 5. Snow and ice only exist on a mountain above 16,000 feet in the summertime. Calculate this height in meters and rods. Please express your answers to one decimal place accuracy.
Geography 121, Global Physical Environment Problem Set 1 Please make sure to show all work. When you compose your assignment, make sure to retype the problem questions before starting your calculations. It is expected an appropriate atlas will be used to look up latitude for questions 3-5. 1. If 0.95 centimeters on the map represents 17 miles highway distance, what is the Representative Fraction (RF) scale? Please express your answer in appropriate RF scale format. 2. If 0.2 inch on the map represents 9 miles of open water on Lake Superior, what is the RF scale? Please express your answer in appropriate RF scale format. 3. Calculate the sun angle (noon sun angle) for Oklahoma City, Oklahoma, on June 21. Please express your answer to one decimal place accuracy. 4. Calculate the sun angle (noon sun angle) for Cape Town, South Africa, on June 21. Please express your answer to one decimal place accuracy. 5. Calculate the sun angle (noon sun angle) for Perth, Australia, on the fall equinox. Please express your answer to one decimal place accuracy.

1. If the temperature outside is 10° F, calculate this temperature in degrees Celsius (° C). Please
express your answer to one decimal place accuracy.
1𝐹 = −17.2222°𝐶
𝑇ℎ𝑒𝑟𝑒𝑓𝑜𝑟𝑒;
10𝐹 = (10 ∗ −17.2222)
= −172.2°𝐶
2. A meteorologist reports that a thunderstorm is producing heavy rain at the rate of 6 centimeters
per hour. Calculate this rate in inches per hour. Please express your answer to one decimal
place accuracy.
1𝑐𝑚 = 0.393701𝑖𝑛𝑐ℎ𝑒𝑠
9𝑐𝑚 = (9 ∗ 0.393701) 𝑖𝑛𝑐ℎ𝑒𝑠

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
