The earth is made up of several concentric layers as follows:
A.The lithosphere
B.The mesosphere
C.The Barysphere
D.The hydrosphere
E.The atmosphere
THE LITHOSPHERE: This refers to the Earth's crust which comprises two distinct parts namely the sial and the sima.The sial and Sina are collectively referred to as the Earth's crust.
THE MESOSPHERE: Immediately beneath the lithosphere is the mantle otherwise known as the mesosphere.It is a very thick layer rich in a mineral called olivine.
THE BARYSPHERE: The inner-most layer is known as the core of Barysphere which was generally believed to be in liquid state because of high temperature and high pressure in the interior.
THE HYDROSPHERE: The ocean and seas found on the sial the outer part of the Earth's crust are collecting referred to as the hydrosphere.
THE ATMOSPHERE: Above the sial and extending skywards is the atmosphere made up of a mass of gases.
