1. The sum total of all terrestrial life: Mrs. Timmons bought a book about geobenthos in order to read about living creatures existing on land, but not in aquatic regions.
2. That part of the bottom of a stream or lake not covered by vegetation: Mrs. Smith's friend borrowed a book from the library about geobenthos, which was all about seabeds and lakebeds.

An individual who studies the biosphere, or in the combination of geology and biology: A geobiologist specializes in the interdisciplinary field of scientific research that explores interactions between the biosphere, the lithosphere, and the atmosphere.

The study of the biosphere and the physical Earth: Geobiology is a relatively new field and its subject areas flow into portions of ecology, microbiology, palaeontology, soil science, and evolutionary biology.

Geobiology is an interdisciplinary field of scientific research that explores interactions between the biosphere and the lithosphere and/or the atmosphere.

Geobiology is also concerned with the study of terrestrial life.

A plant that is associated with dry land: Mr. Plant asked his students to look up information regarding geobions, or vegetation that grows on land, and not those plants that grow in water.

In biology, an organism spending its whole life in the soil or in the ground: Earthworms, grubs, centipedes, millipedes, snails, slugs, and insect larvae are just a few forms of life that are considered to be geobionts and exist in soil.

Geobionts permanently inhabit the soil and affect its structure.

A reference to an organism that spends its entire life in the ground: In the garden, little Alice watched a geobiontic earthworm crawl around in the flowerbed.

The total life of the land; terrestrial life: Geobios entails that part of the Earth's surface which is occupied by terrestrial organisms.

A reference to the scientific study of the effects of various geological environments on plants: Jane discovered some geobotanical articles at the library that she could use for her botany class at school.

In geology, the visual study of plant life to discover ore: Geobotanical prospecting includes distribution and morphology to determine the possible presence of ore deposits, climatic conditions, soil composition, etc.

Someone who studies the geographic distribution of plants: Mr. Tree was a geobotanist who loved studying plants in comparison to their geological environments.

The study of the geographic distribution of plants: Geobotany deals with plants in relation to geography, ecology, and their geologic habitat.

Pertaining to fruit maturing underground as a result of the young fruit being pushed underground by curvature of a stalk after fertilization: An example of a geocarpic fruit is the peanut, one of very few such geocarpic plants!

The production, or ripening, of fruits underground: Besides peanuts, potatoes, sweet potatoes, and ginger go through the process of geocarpy

Referring to the solar system when it is regarded as having the Earth as its center: From a geocentric point of view, many people think of the Earth as being the center of all matter.

A geocentric theory or belief maintains that the Earth and its inhabitants are the center of existence.

A certain geocentric location of the Earth is thought to be a reference point for measurement.

1. In astronomy, geocentric coordinates: A geocentric coordinate system is an arrangement of celestial coordinates located with respect to the center of the Earth.
2. In cartography, a set of map coordinates which define the position of a point with respect to the center of the Earth: In class, Mr. Smart asked the students to study the geocentric coordinate system and to measure the different geocentric distances from given points.
