1. weather is condition of atmosphere over short period of time, climate is the average weather condition of the area over a long period of time

2.temperature, pressure, humidity,wind and precipitation

3 nitrogen 78% and oxygen 21%

4. industrial and automobile gases

5. prevents us from UV rays of the sun

6. from lowest to higest is troposphere, stratosphere,mesosphere,inosphere and exosphere

temperature first decreases and then increases and finally falls when reaches to the upper most layer
