geographical unit, geographic unit
An area based primarily on hydrologic boundaries adjusted as needed using a specified set of criteria to accommodate the inventory and analysis of natural resources.

A geographic unit can vary in scale depending on the criteria used, the level of inventory and analysis needed, and the problems perceived. In all cases, geographic units incorporate both groundwater and surface water.

Characterized by the scientific study of the surface of the earth including the topographical features of a region, or regions, of the earth.
1. The study of the natural features of the earth's surface, comprising topography, climate, soil, vegetation, etc. and man's responses to them.
2. The physical features of a region, area, or place; usually, the surface features.
3. The science that deals with the description of land, sea, and air and the distribution of plant and animal life, including humans.
4. The scientific study of the earth, including its composition, structure, physical properties, and history.

Geology is commonly divided into subdisciplines concerned with the chemical makeup of the earth, including:

  • The study of minerals (mineralogy) and rocks (petrology).
  • The structure of the earth (structural geology) and volcanic phenomena (volcanology).
  • Landforms and the processes that produce them (geomorphology and glaciology).
  • The geologic history, including the study of fossils (paleontology).
  • The development of sedimentary strata (stratigraphy).
  • The evolution of planetary bodies and their satellites (astrogeology).
  • Economic geology and its various branches; such as, mining geology and petroleum geology.
  • Also, some major fields closely allied to geology are geodesy, geophysics, and geochemistry.
geography of energy
The study of energy development, transportation, markets, or the use of patterns from a geographical perspective.
geolith; rock-stratigraphic unit; lithologic unit; lithostratic unit; lithostratigraphic unit; rock unit

Rock-stratigraphic units include groups, formations, members, and beds.

geological oceanography; marine geology; submarine geology
The study of the features of the floors and margins of the oceans, including descriptions of topography, composition of bottom materials, interaction of sediments and rocks with air and sea water, the effects of movements in the mantle on the sea floor, and action of wave energy in the submarine crust of the earth.
