<h2><u>Air particles at different layers of the atmosphere</u></h2>

Earth's atmosphere has four layers namely Troposphere, Stratosphere , Mesosphere and Thermosphere where troposphere is nearest to the earth and thermosphere is farthest and temperature increases with increase in altitude of the layer of atmosphere. So, temperature is highest in thermosphere and lowest in troposphere. so the ascending order of temperature is Troposphere < Stratosphere < Mesosphere < Thermosphere.

Dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and a small amounts of some other gases by volume. It also contains a varied amount of water vapor, around 1% at sea level, on average and 0.4% over the entire atmosphere.

The lithosphere consists of a crust and a portion of a solid upper mantle.
Below the lithosphere is the asthenosphere.
There are two types of crusts: the continental crust and the oceanic crust.

Write a short story describing the application of the system of classification of living creatures

Citrus2011 [14]

All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other. A practical way of understanding the classification of living organisms is that organisms are linked to other similar organisms via family trees. The classification of all living creatures includes at least four levels: order, families, genus and species.
