Calculate the height of mountain if the temperature at the foot is 30 and its top is ( -6)
The amount change in temp = temp. at its foot - at its top= 30-(-6) = 36 degree c H of mountain = change in temp/ 6.5=36/6.5= 5.53 KM
................ is the coldest layer
mesosphere
.....................Used in extinguushing fire
halons
............ radiation has thermnal effect
infarred
G.R van- Allen Belts play an important role in protecting earth
Bec. they scatter the harmful charged cosmic radiation away from the earth
ozone layer is extends from ...... to ........ KM above sea level
20 to 40
............ is region between mesosphere and thermossphere
mesopause
What happen when there are no van allen belts?
The harmful cosmic ray will reach the earth surface
give example for Greenhouuse gase
halons
What happen when overuse of freon
Erosion of ozone layer increase, and also the temp. of the earth increase
Write the scientific term : It is type of UV rays that doesn't pentrates the ozon layer by a percentage 100%
far UV rays
true or false infared radiation has chemical effect
false UV
