我想問環保和大氣層有什麼關係

The first thing people see, in the morning, when they walk outside is the sky or the colored sun. Is this world giving us the privilege of seeing the natural colors of the sun
through all the layers of pollution within the air (Dinanike 31)? Not only are beautiful
sights such as this hidden behind the pollution this world causes everyday,
but an increase in diseases, infections and death occurs. What causes pollution?
What can we do to prevent it, and get rid of it? Is it fair to the children of the future to
have to suffer the consequences that pollution causes? Why not take care of the problem now? Factory and business owners care of the problem now? Factory and business owners have the ability to prevent air pollution..
Air pollution is the presence in the atmosphere of harmful gases, liquids, or solids.
Air pollution, known as smoke pollution for many years, resulted from coal combustion
(Hodges 526). Smog has been a problem in coal-burning areas for several centuries.
Smog finally decreased when coal combustion was replaced by oil and gas combustion.
Air pollution is caused by a number of different types of pollutants.
Acid rain is a problem that has plagued earth for years. It is poisoning our waters,
animals, plants, soil, and more. It is a problem that can not be ignored or it might have
catastrophic results on our environment. Acid rain is caused by air pollution, which is
Scientists have discovered that air pollution from the burning of fossil fuels is the
major cause of acid rain. Power plants and factories burn coal and oil, which is used to
produce the electricity we need to heat and light our homes and to run our electric
appliances. We also burn natural gas, coal, and oil to heat our homes, and our cars,
trucks, boats, and airplanes use gasoline to run, which is another fossil fuel.
The smoke and fumes from burning fossil fuels rise into the atmosphere and combine
with the moisture in the air to form acid rain. The main chemicals in air pollution that
create acid rain are sulfur dioxide and nitrogen oxides. Acid rain usually forms high in the
clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants.
This forms a mild solution of sulfuric acid and nitric acid. Sunlight then increases the rate
of these reactions. Rainwater, snow, fog.

Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen,21% oxygen, 0.93% argon, 0.04% carbon dioxide, and trace amounts of other gases, in addition to water vapor. This mixture of gases is commonly known as air. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night.
There is no definite boundary between the atmosphere and outer space. It slowly becomes thinner and fades away into space. Three quarters of the atmosphere's mass is within 11 km of the planetary surface. In the United States, persons who travel above an altitude of 50.0 miles (80.5 km) are designated as astronauts. An altitude of 120 km (75 mi or 400,000 ft) marks the boundary where atmospheric effects become noticeable during re-entry. The Karman line, at 100 km (62 miles), is also frequently used as the boundary between atmosphere and outer space.
The temperature of the Earth's atmosphere varies with altitude; the mathematical relationship between temperature and altitude varies between the different atmospheric layers:
troposphere: From the Greek word "tropos" meaning to turn or mix. The troposphere is the lowest layer of the atmosphere starting at the surface going up to between 7 km (4.4 mi) at the poles and 17 km (10.6 mi) at the equator with some variation due to weather factors. The troposphere has a great deal of vertical mixing due to solar heating at the surface. This heating warms air masses, which then rise to release latent heat as sensible heat that further uplifts the air mass. This process continues until all water vapor is removed. In the troposphere, on average, temperature decreases with height due to expansive cooling.
stratosphere: from that 7–17 km range to about 50 km, temperature increasing with height.
mesosphere: from about 50 km to the range of 80 km to 85 km, temperature decreasing with height.
thermosphere: from 80–85 km to 640+ km, temperature increasing with height.
exosphere: from 500-1000 km up to 10,000 km, free-moving particles that may migrate into and out of the magnetosphere or the solar wind.
The boundaries between these regions are named the tropopause, stratopause, mesopause, thermopause and exobase.
The average temperature of the atmosphere at the surface of Earth is 14 °C
Air pollution is a chemical, physical (e.g. particulate matter), or biological agent that modifies the natural characteristics of the atmosphere. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the earth's ecosystems.
Worldwide air pollution is responsible for large numbers of deaths and cases of respiratory disease. Enforced air quality standards, like the Clean Air Act in the United States, have reduced the presence of some pollutants. While major stationary sources are often identified with air pollution, the greatest source of emissions are actually mobile sources, principally the automobile. Gases such as carbon dioxide, which contribute to global warming, have recently gained recognition as pollutants.
