Atmospheric pauses are the dynamic boundaries between each of the earths atmospheric layers. Each pause contains characteristics of both layers in varying concentrations.
the tempetature varies in each of the atmospheric layers; search up in Google images "Temperature of atmospheric layers" for a graph image. It's sure to help :)
As you go higher, air (atmospheric) pressure gets reduced.
Different layers of atmosphere protect us. They do it by blocking the unwanted radiations of the sun.
they are called layers
In ancient times, it was believed that there were seven heavens, one above the other. God sat in the highest heaven, while various angels and spirits inhabited each of the lower heavens. Rather than based on atmospheric layers, it was really based on the motions of the sun, moon, planets and stars, since each was believed to occupy a different level in the heavens.
1- why should alternate layers be laid at 90 degrees to each other?
wet ice causes ice layers to slide over each other
Because there different kind of layers and they each are totally different from each other!
There is no interaction of ozone layer with other layers. All of them are independent of each other.
If both layers are water, then make one of them warmer than the other one.
