1. MEANING OF GREEN HOUSE1. MEANING OF GREEN HOUSE

A greenhouse is a building made by glass sheet where A greenhouse is a building made by glass sheet where plants are cultivated.plants are cultivated.

In briefly, a greenhouse is a structure with a glass or In briefly, a greenhouse is a structure with a glass or plastic roof and glass or plastic walls. When the sun’s plastic roof and glass or plastic walls. When the sun’s ray reflects on glass then the house gathers heat by ray reflects on glass then the house gathers heat by radiation and the house keeps remain hot because the radiation and the house keeps remain hot because the glass blocked the sun rays. In that types of house glass blocked the sun rays. In that types of house some plants are cultivated where normal temperature some plants are cultivated where normal temperature is not enough for cultivate plants. Here is one image is not enough for cultivate plants. Here is one image of a normal look green house,of a normal look green house,

2.MEANING OF GREEN HOUSE EFFECT2.MEANING OF GREEN HOUSE EFFECT

The greenhouse effect discovered by Joseph The greenhouse effect discovered by Joseph Fourier in 1824 and first investigated by Arrhenius in Fourier in 1824 and first investigated by Arrhenius in 1896.1896.

The Earth has a natural temperature control The Earth has a natural temperature control system. Certain atmospheric gases are maintain the system. Certain atmospheric gases are maintain the system and are known as greenhouse gases. On average, system and are known as greenhouse gases. On average, about one third of the solar radiation that hits the earth is about one third of the solar radiation that hits the earth is reflected back to space. Some is absorbed by the reflected back to space. Some is absorbed by the atmosphere but most is absorbed by the land and oceans. atmosphere but most is absorbed by the land and oceans. The Earth's surface becomes warm and as a result emits The Earth's surface becomes warm and as a result emits infrared radiation. The greenhouse gases trap the infrared radiation. The greenhouse gases trap the infrared radiation, thus warming the atmosphere.infrared radiation, thus warming the atmosphere.

Naturally occurring greenhouse gases include water Naturally occurring greenhouse gases include water vapors, carbon dioxide, ozone, methane and nitrous vapors, carbon dioxide, ozone, methane and nitrous oxide, and together create a natural greenhouse effect. oxide, and together create a natural greenhouse effect. However, human activities are causing to increase the However, human activities are causing to increase the greenhouse gas levels in the atmosphere in an extreme greenhouse gas levels in the atmosphere in an extreme stage that so the full process of natural green house is stage that so the full process of natural green house is happened massively that is called green house effect. happened massively that is called green house effect. Though the full process is look like the green house so Though the full process is look like the green house so is called green house effect also. Here the carbon is called green house effect also. Here the carbon dioxide gas is like glass sheet and we are like plants.dioxide gas is like glass sheet and we are like plants.Here is a simple figure which mentions total process of Here is a simple figure which mentions total process of green house effect, green house effect,

3. MAIN CAUSES OF GREEN HOUSE EFFECT3. MAIN CAUSES OF GREEN HOUSE EFFECT

Human are mainly accused for the green house effect. Human are mainly accused for the green house effect. We know that the enhancement of carbon dioxide in an We know that the enhancement of carbon dioxide in an extreme range is the main reason for green house effect. extreme range is the main reason for green house effect. So from where the carbon dioxide is produced they are So from where the carbon dioxide is produced they are the main cause for green house effect.the main cause for green house effect.Here some examples are mentioned what are really Here some examples are mentioned what are really responsible for producing carbon dioxide,responsible for producing carbon dioxide,

a. Deforestationa. DeforestationPlant destruction in a large scale is one of the main Plant destruction in a large scale is one of the main reasons for green house effect. Because trees are absorb reasons for green house effect. Because trees are absorb the Carbon-dioxide and produce Oxygen gas.the Carbon-dioxide and produce Oxygen gas.

b. Increasing of population :b. Increasing of population :

A huge number of human produced a huge Carbon-dioxide so it A huge number of human produced a huge Carbon-dioxide so it another reason of green house effect.another reason of green house effect.

Here is an example for that,Here is an example for that,

c. Burning fuel:c. Burning fuel:Burning fuel like petrol, diesel, octane, coal and kerosene in Burning fuel like petrol, diesel, octane, coal and kerosene in a vast scale is another main reason for increasing Carbon-a vast scale is another main reason for increasing Carbon-dioxide. That is responsible for green house effect. Here this dioxide. That is responsible for green house effect. Here this image will make it clearimage will make it clear, ,

d. Industrial Carbon-d. Industrial Carbon-dioxide production:dioxide production:

Different type of Different type of industries produced industries produced Carbon-dioxide and Carbon-dioxide and other harmful gases in other harmful gases in a large scale. This a large scale. This picture mentioned itpicture mentioned it,,

e. C.F.C. gas:e. C.F.C. gas:

Many man maid Many man maid things like things like refrigerators, refrigerators, aerosol cans, fire aerosol cans, fire extinguisher extinguisher chemicals chemicals produced C.F.C. produced C.F.C. gases that are gases that are most helpful for most helpful for green house green house effect. It is like,effect. It is like,

f. Nuclear reactor:f. Nuclear reactor:

In modern world nuclear reactor is used in commonly In modern world nuclear reactor is used in commonly is also responsible for produced carbon-dioxide in a is also responsible for produced carbon-dioxide in a large scale. This is happened like this,large scale. This is happened like this,

g. Inconsiderate Urbanization: g. Inconsiderate Urbanization: Inconsiderate urbanization is another cause of green house effect Inconsiderate urbanization is another cause of green house effect that means some one build infrastructure with out planning. that means some one build infrastructure with out planning. Here is an example,Here is an example,
