Components # 1. Hydrosphere:
It includes water in the oceans, lakes, ponds, etc., and covers about 73% area of the earth’s surface. Water is the major inorganic nutrient needed by all living organisms, hence, water is essential to all life. First life originated in water.
The means of obtaining and conserving water have shaped the nature of terrestrial life; means of living within the water have the overwhelming influence on aquatic life. Water is one of the main agents in pedogenesis and is also the medium for several different ecosystems.
Components # 2. Atmosphere:
It is a thick gaseous mantle which envelopes the hydrosphere and earth’s surface, called the air. It supplies oxygen, nitrogen, carbon dioxide and other gases and is subjected to physical cycles by the sun and spin of earth. Cooled polar air sinks, while warm equatorial air rises and the axial rotation of the earth causes to shift air masses laterally resulting into the formation of global air currents.
Components # 3. Lithosphere:
The solid component of earth is called lithosphere. It is multilayered and includes following three main layers: crust, mantle and core (outer and inner). The core is the central fluid or vapourized sphere having diameter of about 2500 km from the centre and is possibly composed of nickel-iron. The mantle extends about 2900 km above the core. This is in a molten state.
The crust is the outermost solid zone of the earth and it is about 8 to 40 km above mantle. The crust is very complex and its surface is covered with the soil supporting rich and varied Cross section of earth showing different layers, biotic communities. The soil provides food, shelter, anchorage and concealment from predators to living organisms.

The biosphere is made of three parts, called the lithosphere, atmosphere and hydrosphere. Some portions of each may not support life, however; for example, the upper regions of the atmosphere do not support life, while the lower regions do.
