Atmosphere:It contains all the gaseous layers that surrounds the earth and held tightly by earth’s gravity.
Cryosphere:It is composed of all melting glaciers and polar ice caps of the mountains.
For billions of years all these layers are interlinked and deeply affected one another.For instance,melting of glaciers and polar regions ice (cryosphere) returns to the oceans (hydrosphere) results sea level water rises which turn into floods and destroys the low-lying land (lithosphere) and affect coastal regions life (biosphere).
