Green house effect and global warming.

Green house effect and global warming.

The increase in temperature of earth in globe due to green house gases is called global warming.

Explanation:

When solar energy strike on  earth  it heat up surface of earth, some of heat is absorbed by earth and some radiate back to upper atmosphere, but due to presence of green house gases in atmosphere do not allow heat to escape from atmosphere as a result temperature of earth in globe increase so it is called global warming.

Green house gases:

The gases that are present in atmosphere in higher concentration  and trapped solar heat after emitting from earth surface and do not allow to escape from earth atmosphere, these gases are called green house gases included carbondioxide,60% methane 20%, chlorofluorocarbons,10% water vapour and oxide of nitrogen 5%.

All these gases mainly come from industrialization and other source of pollution. 

The normal temperature of earth atmosphere is near about 15 degree Celsius, but in last decade temperature increase 0.6 degree due to pollution, due to this reason polar ice caps melted and water body in ocean increase, polar ice caps are responsible for weather cycle and that is also effected due to green house gases.
