geo-, ge- +

The branch pf geology pertaining to ancient geological conditions or situations: Wendy was quite interested in the geological formations of the distant past and so she decided to study archaeogeology at the university in her city.

Any systematic collection of ancient geophysical data: The Geological Society in London has lecture programs set up regarding archaeo-geophysics for those who are interested in the ancient past.

The use of geological techniques and methods in archaeological work: Archeological geology is different from geoarchaeology in that it is a subfield of archaeology focusing on the physical context of deposits.

A branch of geology that studies the geological formations of the remote past: Archeogeology integrates some archaeological fields with relevant geological sciences to investigate the geological effects on historical sites, monuments, and other properties concerning constructive materials (type, situation, and position of mines and other natural resources) and destructive geological forces in the environment, such as earthquakes, faults, and earth movements.

Archeogeologies make use of geological maps that indicate prehistoric layers of the earth's crust, faults, hisoric and recently found mines, hydrology layers, and seismological information all of which provide basic information in this field.

1. A biogeographical and zoogeographical area, or division, comprising the Holarctic: The Arctogaea includes the Nearctic, Palaearctic, and the Oriental and Ethiopian regions.
2. Etymology: Greek Arktos, "Great Bear" plus gaia, "earth".

Other forms include: Arctogaean, Arctogean, Arctogaeal, Arctogeal, Arctogaeic, and Arctogeic.

The study of the origin, history, and structure of cosmic bodies other than Earth; the geology of celestial bodies: Astrogeology is the science dealing with the arrangement and composition of planets and other heavenly bodies in the solar system.

The circulation of chemical components through the biosphere from, or to, the lithosphere, atmosphere, and hydrosphere: The biogeochemical cycle includes the exchange of elements, like oxygen, carbon, or nitrogen, in the environment between storage pools, such as the atmosphere, biota, oceans, soils, the earth's crust, and human society.

The branch of science that studies the biological, chemical, and geological aspects of environmental processes: Biogeochemistry deals with the relation of chemicals found in the soil to living organisms. It is the biological application of geochemistry.

Biogeochemistry is the study of the influence of living organisms and life processes on the chemical structure and history of the Earth.

Biogeochemistry also includes the study of the interactions between the biosphere and its mineral environment, for example, the study of the effect of living organisms on the weathering of rocks and of the concentration of elements by living systems.

A diagram , a collection, or a chart showing the geographical distribution of living things: Judy had to analyse the biogeograph of animals and vegetation in her region in order to give a talk to the class the following week.

1. A specialist in biogeography, or someone who studies the distributions of living things: Tom's father was a biogeographer who was an expert in plant and animal life in the earth's environment and knew a lot about the biological and historical factors that produced such distributions.
2 .A scientist who studies the spacial distributions of individual organisms in biotic communities: The biotic communities that a biogeographer is concerned with are composed of plants and animals and of ecosystems, or environmental systems, which are associations of biotic communities interacting with their environments.

An ecosystem may be defined and studied at sites in areas ranging from a small pond to a global biome, such as prairies or tropical rain forests.

A reference to the science of the geographical distribution of living things: Mr. Jackson was very interested in the biogeographic spreading of wild animals in his country.

Referring to the study of the geographic or earthly distribution of living organisms: Mrs. Thompson found a book in the library dealing with the biogeographical aspects of plants and animals.

A description of how situations involve the geographic or the worldly distribution of living organisms: In class, Judy learned about a biogeographically isolated area of plants and animals.

The science of the geographical distribution of living things, animal (zoogeography) and vegetable (phytogeography): Biogeography is the study of the geographical distributions of organisms, their habitats (ecological biogeography), and the historical and biological factors that produced them (historical biogeography).

In ecology, that part of the lithosphere within which living organisms can exist: The biogeosphere is the region of the earth that reaches from the surface of the top crust down to the maximum depth in which organisms can live.
