By: Eglantina Brewer Chemistry 10-1 Discuss the Relationships Among Earth’s Systems and How Those Systems are Being Modified Due To Human Activity By: Eglantina Brewer Chemistry 10-1
OBJECTIVES
The Destruction of Earth’s Systems What is human activity? Actions that people do that might have a negative consequence Source of food supply An energy source Source of recreation and constructions Major source of medicines Natural resources for industrial products Earth’s system can provide us humans with Desires/ Solutions Destruction of the “pure” system
Biosphere - Atmosphere NATURAL: Biosphere releases carbon into the atmosphere through the biomass; therefore there is a small quantity of CO2 in the air HUMANS: Interrupting this pure relationships by releasing more carbon dioxide into the atmosphere Deforestation (eliminating carbonsinks)(construction) Burning fossil fuels Burn forests Certain agricultural practices Waste management CAUSES: Global warming, change in the ecosystems, and acidification of the ocean
Atmosphere - Cryosphere NATURAL: The atmosphere provides the perfect conditions for the cryosphere to exist HUMANS: Releasing a lot of carbon dioxide/ greenhouse gasses(methane, nitrous oxide, etc.) 2/3rds of the current rates- glacial melting is due to human activity 25% - 1851 to 2010 65% - 1991 to 2010 Aerosols CFC’s (coolants) Eating meat Production of cattle CAUSES: Global warming (greater impact) Ocean Circulations are disrupted Sea levels rise Less habitat for the animals in the poles
Cryosphere - Hydrosphere (minor) CAUSES: Change in temperature More water in ocean Greater storms (force) Sea levels rise Over population (central regions) Floods (coastal regions) http://ocean.nationalgeographic.com/ocean/critical-issues-sea-level-rise/
Hydrosphere - Biosphere NATURAL: Provides a habitat for many animals/ plants Crucial sphere- benefits to humans and animals HUMANS: Wastes Grand quantity of litter Excess of carbon CAUSES: Fish intoxicated Human health Resource of food Decrease in result of animals/ plants Ocean becomes acidic
Geosphere - Biosphere NATURAL: Geosphere provides pure soil when it comes to the formation of the biosphere HUMANS: Mining Extraction Ore Extraction Chemicals Intoxication (pesticides/ fertilizers) CAUSES: Polluting our ecosystems Natural Vegetation will be scarce Biomass won’t develop properly Loss in species
Conclution https://www.youtube.com/watch?v=WfGMYdalCIU Earth’s systems are vital Many ways humans can decrease the harmful activites Consciousness Being informed (consequences) https://www.youtube.com/watch?v=5eTCZ9L834s
QUIZ TIME! What were the five important relationships of shperes that I talked about?
Answer #1 Biosphere- Geosphere Biosphere - Hydrosphere Hysrosphere - Crynosphere Atmosphere - Crynosphere Biosphere - Atmosphere
Q #2 What are some human activities that are destroying the relationship between the geosphere and the biosphere? (Be specific)
Answer #2 Mining extraction Chemicals Pesticides and Fertilizers Ore extraction Chemicals Pesticides and Fertilizers
Q #3 What are the causes of human activity interfering with the relationship between the crynosphere and the hydrosphere?
Answer #3 Change in temperature More water in ocean Greater storms (force) Sea levels rise Over population (central regions) Floods (coastal regions)
Reflection Out-loud Everyone has to come up with something they’ll do or stop doing to help decrease the impact on the relationship between spheres. Explain which sphere you chose and what will you do.
