Geography 

Geography is derived from the Greek word "geographia" which may be translated literally as "description of the earth". One aspect is known as physical geography which consists of the systematic study of the earth such as landforms, climate, oceans, and other natural resources. The field of the geographers is limited to a thin shell of the earth's surface extending about 45 kilometers into the atmosphere and about four kilometers toward the earth's interior. Only within this zone, some 49 kilometers in thickness are found the conditions that make ordinary life possible. This referred to as the human habitat.
