Gopal warming and green house effect

Answer 1

Green House Effect and Global Warming
=====================================

The phenomenon in which atmosphere of earth traps the heat coming from the sun and prevents it from escaping into the outer space is called green house effect. Certain gases, called green house gases [carbon dioxide, methane, ozone, chlorofluorocarbon compounds (CFCs) and water vapour] in the atmosphere absorb the heat given by earth and radiate back it to the surface of the earth. Thus, warming of the earth led to the warming of air due to green house gases. which is called global warming.

Consequences of Green House Effect (or Global Warming)

1. The green house gases are useful in keeping the earth warm with an average temperature of about 15° to 20°C.

2. There may be less rainfall in this temperature zone and more rainfall in the dried areas of the world.

3. Increase in the concentration of CO2 in the atmosphere leads to increase in the temperature of the earth’s surface. As a result evaporation of surface water will increase which further help in the rise of temperature and results in the melting of glaciers and polar ice caps and hence, level of sea water may rise.

Answer 2

global warming is the rise in the average temperature if earth's atmosphere.
its natural process which harms the earth. effect are:
glyceror are melting due to which there are chances of tsunami increasing.
2. ozene layer is getting depleted due to green house effect which cause skin cancer because UV rays come in direct contact with humans skin.
