Explanation:
The behavior of the rocks is influenced by the temperature and pressure conditions inside the earth, this also includes the rate of stress applied upon the rock mass. More the heat and pressure of rocks more will be here transformation.
Convective currents that rise from the asthenosphere are responsible for the movement of plates from the source, as these forces cause the plates to rotate and break up when the gases are released from below the surface of the earth in a very sudden manner.
The layers found within the earth are called core crust and mantle but no such layer atmosphere exists on or above the surface of the earth in any form what so ever.
