Notes 8/30 Tuesday Earth’s atmosphere Stratosphere The layer of the earth’s atmosphere above the troposphere where ozone depletion happens. Also, above the mesosphere so it’s on top and it’s cold in that layer. Troposphere The layer of the earth’s atmosphere that’s located on the very bottom and it’s very hot due to it being a thermal layer of the earth’s atmosphere. ~We live in mesosphere which is the middle layer of the earth’s atmosphere. Increased Greenhouse gases will cause a positive radiative force so the average temperatures will increase seen on the surface. Outcome of this is an enhanced Greenhouse Effect. Carbon cyclea biochemical cycle which has a series of processes involving carbon compounds. Respiration Decomposition; The process involving living organisms with the production of energy and will usually involve the intake of oxygen with the release of carbon dioxide Carbon Cycle: Co2PhotosynthesisOrganic Carbon/Decaying of organismsDead organisms and waste productsRoot RespirationCo2 ~It’s in a circle since it’s a cycle. PhotosynthesisThe process in which a plant uses sunlight to make food from carbon dioxide and water Root respirationThe production of carbon dioxide has respired and or photosynthesis is halting due to the production of carbon dioxide. Decaying: Decomposition of organic matter so breaking down the organic matter CombustionThe process of something being burned Agricultural processing Manufacturing that will process raw materials from the agricultural industry 44% of Co2 is stored in the atmosphere while 26% is stored in the ocean and 30% on land. GDP per capita Climate, water power, wind power, nuclear power, etc can cause a high emission per capita of carbon dioxide so population isn’t always the case. GDP=Gross domestic product and it factors in the average income in that particular country Per Capita What is for each individual in relation to what is taken from each individual person in that particular country EX of Per Capita: China has the most emission of carbon dioxide per capita while the U.S. has nd the 2 most though India has more people so leading back to population isn’t always the case. Climate Climate change is a long term change within the averages of the conditions while climate variation is a shorter term in a change and is a like a cycle in conditions. Anomalies The abnormalities of what is normal and or expected Yes global warming is still an issue and it causes an increase in temperatures. The increase in temperatures due to global warming can cause climate change. Ocean Acidification The decrease in PH levels of an ocean that causes the rise in Co2 and isn’t caused by climate change. Ocean water tends to bit basic so has a PH level of above 7 while if the ocean water were a bit and or overly acidic then PH level would be under 7. Sea levels rising can cause glaciers and ice in the sea to melt, decrease albedo and or increase in decomposition and or increase photosynthesis. Sea levels lowering can cause an increase in albedo, the formation of ice and glaciers, and a decrease in photosynthesis. ~Increase albedo will cool the earth while a decrease in albedo will warm the earth.
