Nations like China, U.S, Russia, cause most air pollution as they are responsible for large scale production at global level as compared to the developing countries like India and Indonesia.
As they have long historical pasts of the utilization of natural resources and have large scale oil and gas refineries and factories like the china, presence of global warming and the spread of greenhouse gases are due to the industrial development of the developed countries.
Larger scale burning of forests, cutting of trees, oil spills and the differences in land use patterns are major factors that influence the pollution.
What usually happens when a parcel of air cools more slowly the air in motion, leads to the formation of clouds as moisture accumulation takes place. Thus the vertical ascent of air reduces its capacity to store or hold water and hence condensation occurs at dew point.
The rising parcel of air cools and descents down the original dew point and results in net condensation. Thus the lifted parcel of air reaches o its 100% concerning Adiabatic cooling.
