Welcome to the Geography Quiz 66

Why do we learn Geography ? I guess, because it helps us to understand the places, and the relationship of people with its environment. Also did you ever try to find out how the Geography word was formed. Well, here is the answer – The word geography can be broken into the two basic elements of “GEO” and “GRAPHY.” Geo comes from the Greek word for Earth (the word Gaea, also meaning earth, derives from the Greek as well). The “ography” part comes from the Greek word graphein, which is literally to write about something. How well do you know about places, environment and our connect with it ?
