Definitions and importance of the study of Physical geography: Geography is the science in which the study of ‘earth’s surface’ and description is done in context to human world and human habitation, in terms of its total characteristics and reciprocal relation. The earth’s surface is not evenly formed over the earth. Human actions also have their impact, everywhere in the field. Geography makes a detailed explanation of all of these. Therefore, it is said that geography is the science of distributions. It analyzes surface variations.

The following are the major definitions of geography:

1. According to Hatner: “The study of variation in the factors related to reasonably related different parts of the earth’s domains.” 

2. According to the geographical dictionary: “Geography is the science of the earth’s surface and its inhabitants.” 

3 According to the Hartshorne: “Geography is the science that explains the description and interpretation of the transformation from one place on earth to another, in the form of the human world.”

Over time, the soil gets mature and this soil is helpful in the creation of the life and its survival.

Land forms are the basis on which human activities are performed. Different, types of human activities develop on different land forms and different types of cultural landscapes are formed.
