GNED 1525: Lab 1 Climate and Atmosphere – Hannah McSweeney This lab requires you to apply what you have learned in Weeks 1 to 3. Due Date : Week 4 (See DC Connect Calendar for your CRN’s due date) Value: 7.5% Submission Format: Electronic, DC Connect Assignments Answer all of the questions below. Use course concepts and terms in your answers. 1. Using Mars as an example, explain how weather and climate are different. (2 marks) Weather is considered the state of the atmosphere at a particular time, usually describing temperature, wind or precipitation. On Mars one example of weather would be that Mars does have seasons, though they vary greatly from what we experience here on Earth. The length of a Martian spring is 194 days, summer is 178 days, autumn is 142 days and winter is 154 days (Mars' atmosphere: Facts about composition and climate, 2023). Climate is considered the average weather conditions prevailing over a place over a long period of time. On Mars and example of climate would be that the average temperature on Mars is about -60°C. 2. In one sentence, what is the main difference in the career of a meteorologist and a climatologist? (1 mark) The main difference between in the career of a meteorologist and a climatologist is that a meteorologist studies short term weather patterns and a climatologist studies long-term weather patterns (climate). 3. Explain how knowing the class average lets you make a "relative" comparison of your work with the class. (1 mark) Knowing the class average helps you make a relative comparison of your work with the class because it allows you to compare whether your mark is above or below the class average. You can then use this comparison to judge how well you are doing in the class in comparison to your peers. 4. Which location would have lower air pressure? Explain why. (2 marks) a. Thun, Switzerland b. Engelberg, Switzerland Engelberg, Switzerland would have a lower air pressure than Thun, Switzerland. This is due to Engelberg having a higher altitude of 3301 feet (Worldwide Elevation Finder, 2023) while Thun only has an elevation of 1841 feet (Worldwide Elevation Finder, 2023). As altitude rises, air pressure drops therefore Engelberg would have lower air pressure.

5. Give three ways that carbon moves through the Geosphere and the Biosphere. (3 marks) One way that carbon moves through the Geosphere to the Biosphere is through photosynthesis; the process where plants use sunlight, water and CO 2 to create oxygen and energy. Another way that carbon moves through the Geosphere and the Biosphere is through the physical weathering process which returns carbon to water and the atmosphere A third way that carbon moves through the Geosphere and the Biosphere is through burning or combustion. 6. Why do global carbon dioxide levels rise from December to March and fall from May to August? (1 mark) Carbon dioxide levels rise from December to March and fall from May to August due to plants absorbing a more substantial amount of carbon dioxide from the atmosphere through photosynthesis during the spring and summer in comparison to the winter. 7. Convert the list below. (3 marks)  1 degree Celsius into kelvin i. 1°C = 274.15°K  29 degrees Celsius into kelvin i. 29°C = 302.15°K  -14 degrees Celsius into kelvin i. -14°C = 259.15°K Assignment length: 300 - 500 words (plus APA references where required) If you are not sure about APA referencing, check out this Durham College resource https://guides.library.durhamcollege.ca/ld.php?content_id=12795278 *DC Connect Assignments uses turnitin.com to check for plagiarism.
