Environmental Studies - Assignment Example

[Due Environmental Studies STEP a) Shallowest is 130 meters, while deepest is 2060 meters. b) It increases. This is because the oldest ice or gas is usually found in the deepest depths. c) Ice and gas are two different elements with different qualities. It so happens that their age would also differ depending on their qualities. d) 2.53 years younger. e) It is smallest at the bottom of the core. This is because it is exposed to elements. STEP 2 b) Very reliable c) 160.73 and 28.1 years ago respectively STEP 3 10.

Carbon dioxide and temperature are directly proportional 11. CH4 is more closely correlated with temperature. This is because it is lighter than CO2. 12. They are inversely proportional 13. 199.81 and 594.65 14. CO2 = 289.76 – 189.23, which is 100.53. CH4 = 273.4 – 197.37, which is 76.03 A combination of effects of the Antarctic, Southern Ocean, processes in the tropics and in the Norther Hemisphere, where the primary sources of methane are located, had a big influence. The close correlation between CO2 concentration and Antarctic temperature indicates that the Southern Ocean played an important role in causing the CO2 increase.

However, the similarity of changes in CO2 concentration and variations of atmospheric methane concentration suggests that processes in the tropics and in the Northern Hemisphere, where the main sources for methane are located, also had substantial effects on atmospheric CO2 concentrations. Part 3: Hypothesis Activity The time period with extremely elevated atmospheric carbon dioxide levels, combined with the rings has a big influence on the patterns of increasingly hot summers and increasing torrential storms in the two cities.
