Definition of Physical Geography:
The physiological environment of the surface of the crust and the different geophysical processes acting in it, the study of the science of science is considered as a natural geography. Most geographers are interested in dividing geography into two categories called natural and human. Again many people are not able to ignore biosphere ecology on earth, and divide the geography into three branches called natural, human and biosphere. Over the past few decades, massive changes have been made in definition, content and reading methods of natural geography. Initially, natural geography could only mean the study of natural environment (landlessness, water and air). For example, according to Arthur Homs (Arther Holmes, 1960), "the surface of the Earth's surface, the oceans and the atmosphere, which constitute the natural environment, its study is the natural geography. According to Carl Ritter, (1779-1859), "Natural Geography is the branch of science that considers all of the Earth's composition, diversity and relationship as a distinct unit." Hartshorn said, "True, well-defined and reasonable description and explanation of the dynamical properties of the earth Provided natural geography.
From this point of view, natural geography is not only the comprehension of certain geological-related topics, it also reviews the interaction type of human activity with natural environment. As a founding branch of geography, natural geogs study the spatial type and the relativistic relations of the elements of the earth's surface in the regional context. In addition, it also explains the reasons for the intercourse with the regional nature, as well as the reasons for the change in the elements of the environment. From this it can be said that the detailed study of the biosphere, which is the basis for the land, air, water and livelihood of animals and plants, is the study of natural geography.
