4. Geography Its Nature And Perspective

5. Population Density
Density is measured with a ration of the number of items within a defined unit of area. For exampled, human population density is typically measured according to the number of inhabitants per square mile or square kilometer of land. Because it is a ratio of quantity per unit of area, density always expresses a relative value

6. Environmental Determinism
Definition: The belief that the physical environment has played a major role in the cultural development of a people or locale. Also called environmentalism.
Examples: In previous years, environmental determinism was popular and it was acceptable to believe that cultures were ruled by their environment.
The well-known contrast between the energetic people of the most progressive parts of the temperate zone and the inert inhabitants of the tropics and even of intermediate regions, such as Persia, is largely due to climate the people of the cyclonic regions rank so far above those of the other parts of the world that they are the natural leaders.
Ellsworth Huntington, Principles of Human Geography, 1940

7. Environmental Possibilism
A philosophy seen in contrast to environmental determinism that declares that although environmental conditions do have an influence on human and cultural development, people have varied possibilities in how they decide to live within a given environment.
Even possibilism has its limitations, for it encourages a line of inquiry that starts with the physical environment and asks what it allows. Yet human cultures have frequently pushed the boundaries of what was once thought to be environmentally possible by virtue of their own ideas and ingenuity.
Harm de Blij, Human Geography, 7th ed., page 33.

8. Site and SITUATION
Site refers to a place’s absolute location, often described in terms of its physical geography. Situation, on the other hand, refers to a place’s location relative to external social relations, systems, or networks
