Geography | the study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources, land use, and industries. |
Character of a place | include land forms, bodies of water, climate, soils, natural vegetation, and animal life. |
Absolute location | A point on the earth's surface expressed by a coordinate system such as latitude and longitude. |
GIS | geographical information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data. |
Hemisphere | half of the terrestrial globe or celestial sphere, especially one of the halves into which the earth is divided. |
