Chemistry Of The Atmospere Flashcards
Phase 1
During the first billion years of the earths existence. There was intense volcanic activity that release gases that formed the early atmosphere and what are people that condensed to from the ocean
It was mainly carbon dioxide which lead to no oxygen gases
Lekan activities also release nitrogen, which part of the atmosphere overtime, as well as water vapour, and small amount of methane and ammonia
Phase 2
When the water vapour in the atmosphere contains informed oceans
Lots of carbon dioxide was removed from the atmosphere as its dissolved into the ocean
How oxygen increase?
Audi and plants produce the oxygen that is now in the atmosphere by photosynthesis
How do you fest produce oxygen about two .7 billion years ago and soon after the oxygen I paid in the atmosphere
Over the next billion years, plants, evolved, and the percentage of oxygen gradually increase the level that enable animals to evoke
How did Carbon dioxide decrease?
Algae and plants decrease the percentage of carbon dioxide in the atmosphere by Photosynthesis
Carbon dioxide was also decreased by information of sedimentary rocks and fossil fuels that contain carbon
Formation of deposits of limestone, coal, oil and natural gas
Crude oil and natural gas was formed from deposit of plankton these fossil fuels from reserves under the seabed when they are trapped in rocks
Coal is a sedimentary rock made from thick plants deposits
Limestone is a sedentary rock. It is mostly made up of calcium carbonate deposits from the shows and skeletons of marine organisms.
Green house gases
Greenhouse gases act like an insulating layer in the edge atmosphere to keep the Earth warm enough to support life
particles absorb certain frequencies of radiation greenhouse gasesDon’t absorb the incoming short wave length radiation but the absorb the long with length radiation that gets reflected back of the earth, then they re-radiate it in all directions
The long wavelength is the radiation resulting in warming the surface of the earth. This is the greenhouse effect.
Human factors that increase greenhouse effect
Deforestation
Burning fossil fuel
Agriculture
Creating waste
Global climate change
 and it’s consequences
An increasing average global temperature is a major cause of climate
And increasing global temperature candid to polar ice cap, melting, causing arise in sea levels, increase flooding in coastal areas and coastal erosion
Changes in rain for pans, cause some reason to get too much or truly to Water. This also changes the temperature that may affect the ability for certain regions to produce food.
The frequency and severity of stomach may be increased
Changing temperature, and the amount of water available in a habitat may affect species leading to differences in distribution
Carbon footprint
The total amount of carbon dioxide and other greenhouse gases emitted over the full life circle of your product, service or events
Reducing carbon footprints
Renewable energy, stores or nuclear energy should be used instead of fossil fuels
Using more effective processes could conserve energy and cut out waste
Government tax companies or individual based on the amount of greenhouse gases, the emits
Governments can also put a cap on a mission of all greenhouse gases that companies make
Technology that captures the CO2 produced by burning fossil before released into the atmosphere
Problems with actions that produce emission of carbon dioxide
Governments are worried that making these changes within impact the economic rules of communities
It will be hard to get everybody to agree
It would be hard to get people to change their lifestyles
Technology has no fully advanced to be able to lower CO2 emissions
Combustion of fuel
This is a major source of atmospheric pollutants
If incomplete, combustion takes place, solid particles of soot and on brand fill are released and carbon monoxide can be produced as well as carbon dioxide
Carbon monoxide
Carbon monoxide can stop our blood from its job of carrying oxygen around the body
This occurs by binding the haemoglobin in your blood that normally carry oxygen select. Oxygen is able to be transported around the body.
A lack of oxygen in the blood can lead to faint in a coma or even death
Carbon monoxide doesn’t have any colour or smell, so it’s very hard to detect
Particulate in the air and their problems
If particles are inhaled, they can be stuck in the lungs and caused damage which can cause respiratory problems
Particulates could reflect sunrise back into space, which would mean there was less light to reach the Earth, which would cause global dimming
So far dockside and oxides of nitrogen
Euphoric dioxide is released to the combustion of fossil fuse, such as cool that contains sulphur impurities
Nitrogen oxides are created from the reaction between the nitrogen and oxygen, the air, caused bye, the heat of the burning
When is gases mixed with cloud, deform, dilute, acid or dilute nitric acid which falls as acid rain
