1) Lithosphere - The land or crust is known as Lithosphere wich is made up of soil, rocks, etc.
2) Atmosphere - The thick layer of air surrounding the earth is known atmosphere. It consists of air.
3) Hydrosphere - The water bodies like ocean, sea, lakes, etc. make up the Hydrosphere. Hydro means water.
4) Biosphere - The realm of the Earth where the other three realms interact is known as biosphere.

The four realms of the earth are:-
i. Lithosphere - the solid portion of earth
ii. Hydrosphere - all the water bodies on earth
iii. Atmosphere - the blanket of air around us
iv. Biosphere - the living world
i. Lithosphere
A lithosphere is the rigid, outermost shell of a terrestrial-type planet or natural satellite that is defined by its rigid mechanical properties. On Earth, it is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater. The outermost shell of a rocky planet, the crust, is defined on the basis of its chemistry and mineralogy.
ii. Hydrosphere
The hydrosphere is the combined mass of water found on, under, and above the surface of a planet, minor planet or natural satellite.
iii. Atmosphere
An atmosphere is a layer of gasessurrounding a planet or other material body, that is held in place by the gravity of that body. An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low.
iv. Biosphere
The biosphere is the worldwide sum of all ecosystems. It can also be termed as the zone of life on Earth, a closed system (apart from solar and cosmic radiation and heat from the interior of the Earth), and largely self-regulating. By the most general biophysiological definition, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere. The biosphere is postulated to have evolved, beginning with a process of biopoiesis (life created naturally from non-living matter) or biogenesis (life created from living matter), at least some 3.5 billion years ago.
