Geography is a wide – domain science whose study area is very extensive. Everything that is visible on the earth’s surface is included in the subject matter of geography. Geography is like a tree in which there are innumerable branches which are related to different facts. But physical geography is the very foundation of all the branches of geography.

The existence of geography remains intact due to physical geography. Without a physical environment, it is not possible to imagine geography. The branches of the geography tree study each aspect of human activity. Direct relationship of all these human actions is given stability in the form of a geography tree by physical geography.

Study is done in the form of physical geography of various terrestrial forms, seas and oceans, biosphere and atmosphere. According to all these, the activities of human beings are accomplished. Physical geography is the synthesized study of many land sciences. Physical geography encompasses all human and social sciences and their branches.

It is not possible to imagine geography without physical geography, as without the roots, the trunk and branches cannot be imagined. Physical geography was developed along with the origin of the earth. Therefore the history of physical geography is very old as is geography. Geography and physical geography both complement each other.

Earth is studied primarily in physical geography and geography is also related to earth. The physical geography is detailed and comprehensive in relationship. Physical geography involves the study of lithosphere, hydrosphere, atmosphere and biosphere. All these components have now become a huge branch of geography, in which the branches have developed in the form of many subjects of science.

Analytical study of the distribution, format and interconnection of physical and biological environment is done under physical geography. It provides information about various components of physical and biological environment and their interaction. It plays its role in the same way as the root of the tree is sure to grow and strengthen the tree.

In the same way, by the growth and development of physical geography, the geography tree has been developed more strong. It can be said in general, that geography without physical geography has no existence of its own. Physical geography is the cornerstone of geography.
