IN OUR PRESENTATION WE WILL DISCUSS THE THREE ATMOSPHERIC EFFECTS OF AIR POLLUTION,.

The Greenhouse Effect and Global Warming are one of the major problems that the world is facing today. An in-depth explanation of global warming and the greenhouse effect along with its causes and effects is given below ..

What is the Greenhouse Effect?. The greenhouse effect is the process thanks to which Earth has a higher temperature than it would have without it. The gases that radiate heat also known as greenhouse gases absorb the energy radiated out by the Earth and reflect a part of it back to Earth. Of all the energy that the Earth receives from the Sun, a part of it around 26% is reflected back to space by the atmosphere and clouds. Some part of it is absorbed by the atmosphere, around 19%..

The rest hits the ground and heats the surface of the Earth. This absorbed energy is radiated out of the earth in the form of Infrared Waves . These IR waves warm the atmosphere above the Earth. The atmosphere again radiates this energy it received from the Earth both upwards and downwards. The energy sent downwards results in a higher equilibrium temperature than if greenhouse gases were absent. This greenhouse effect is essential to supporting life on Earth..

What are Greenhouse Gases?. The greenhouse gases responsible for the greenhouse effect are: Water Vapour Carbon Dioxide Methane Ozone.

Causes of Greenhouse Effect. The following are the factors that are responsible for the cause of greenhouse effect: Deforestation: This is considered to be one of the most responsible factors for the cause of the greenhouse effect. This is due to the reduction in the release of oxygen and absorption of carbon dioxide by the plants. Fossil fuel burning : Fossil fuels such as coal, oil, and natural gases are used as a means of energy which releases a huge amount of harmful gases into the environment. Population: As the population increases, the need for space increases which again results in deforestation..

Global Warming. Global warming refers to the increasing temperature of the Earth’s climate system and its related effects..

What is thinning the ozone layer?. ozone depletion, gradual thinning of Earth’s ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica..

Acid Rain. Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average..

What causes acid rain?. Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain..
