โลกของเรามีชั้นของบรรยากาศห่อหุ้มอย

Our world class atmosphere enveloped by a thick layer of the atmosphere about 15 miles above consists of nitrogen, oxygen, water vapor and dust. And microorganisms in the amount of these gases.Life on Earth is oxygen and the layer of the atmosphere has enough oxygen. To life with a thickness of 5-6 km. Which usually contain various gases is relatively constant nitrogen 78.20.94% oxygen, 09% carbon dioxide and inert 0.We refer to these conditions as "bad air" or "air pollution".

Our world is a layer of the atmosphere wrapped around a thick, about 15 kilometres of the atmosphere. Oxygen, nitrogen, steam, gas, dust and microbes in the amount of these gases. Life on Earth is oxygen gas and oxygen gas has a layer of the atmosphere enough. Dugongs have a thickness of just 5-6 km. Which usually has a composition of various gas-nitrogen gas is somewhat 78.9% oxygen gas 20.94% carbon dioxide inert gas and 0.97% in the quantities of these gases, we considered the fresh air, but whenever a change to the air component has a quantity of dust. Gas smell of smog steam vapor Carbon particles and radiation in kammantaphap more We call these conditions as "bad" or "air, air pollution," he said.

Our world has a layer of atmosphere is wrapped around the thick layer of approximately 15 km, the atmosphere contains oxygen nitrogen gas steam dust and bugs in the gas.As a result of the world's greenhouse gas emissions and oxygen level of the atmosphere is oxygen gas for living with a thickness only 5 - 6 km only, which is normally a component of gas, nitrogen gas is relatively constant 78.09 % gas Ajarn inertia sensor 0 % carbon dioxide and greenhouse gas emissions.97 % of the total volume of gas would be this, we hold that it is a pure air, but when any changes to the components of the air volume of the gas particle smell the smoke the steam with soot and radioactivity in medicine, climateWe call this condition, the "air" or "air pollution".
