-ic

(Greek: a suffix; pertaining to; of the nature of, like; in chemistry, it denotes a higher valence of the element than is expressed by -ous)

geobiontic , more geobiontic, most geobiontic
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.
geocarpic (not comparable)
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!
geocratic , more geocratic, most geocratic
A reference to land-movements that reduce the area of the Earth's surface covered by water: Geocratic action occurs when land expands or continents enlarge, and oceanic areas decrease in size.
geodesic , more geodesic, most geodesic
1. Relating to the geometry of curved surfaces: On their tour of the city, Mrs. Green and her husband admired the geodesic glass dome which was inside a large art museum.
2. The shortest line between two points on a mathematically defined surface (as a straight line on a plane or an arc of a great circle on a sphere): Mr. Smart gave the students in his math class the assignment to find the geodesic path on the defined example surface in their textbook.
3. Etymology: "surveying", from Modern Latin geodaesia, from Greek geodaisia, "division of the earth" (from ge, "earth" + daiein, "divide").
geodetic (not comparable)
Relating to the geometry of curved surfaces: Geodetic theories, techniques, or results of geodesy utilize the precise measurement of the Earth's surface or of points on its rounded surface.
geodic (not comparable)
Descriptive of a small, hollow, usually rounded rock, lined on the inside with inward-pointing crystals: Such geodic rocks, or geodes, are formed when mineral-rich water entering a cavity in a rock undergoes a sudden change in pressure or temperature causing crystals to form from the solution and line the cavity's walls.

geognostic (not comparable)
Characterized by the possession of knowledge of the general structures of the Earth: The students were asked to buy a book , or borrow one from the library, with a sizeable amount of geognostic information and facts for the upcoming semester.
geographic , more geographic, most geographic
Relating to geography or to the geography of a specific region: Cathy received her geographic magazine every month which included the topography of specific regions of her country.
geomagnetic (not comparable)
Relating to the magnetic properties (geomagnetism) of the Earth: A geomagnetic study involves the sources, configurations, and changes in the Earth's magnetic field. It includes the interpretation of the remaining magnetism in rocks as a result of the Earth's magnetic field at the time when the rocks were formed, which is known as "paleomagnetism".

geomantic (not comparable)
Referring to divination by the analysis of figures or lines drawn in dirt (or on paper): Mrs. Mason was interested in the geomantic practises and traditions in China.
geometric , more geometric, most geometric
1. Relating to geometry; using the principles or methods of geometry: The young architect used geometric techniques in her building project.
2. Referring to a design, using or resembling the simple linear figures or forms associated with geometry: Jane used geometric shapes, like circles or triangles, in her patchwork quilt for her bed.
geomorphic (not comparable)
Relating to or resembling the Earth or its shape or surface configuration: Mr. Smart asked his students to read about the geomorphic aspects and structure of the Earth and report on it the next day.
geophilic , more geophilic, most geophilic
1. Pertaining to the growth of life forms that thrive in soil: Fungi, algae, and protozoa are all geophilic organisms.
2. Relating to plants that fruit below the soil surface: Geophilic peanuts, classified as a fruit, are the only fruit that grow under the surface of the earth and are, in addition, the plant's seeds.
geoponic (not comparable)
Of or relating to agriculture: Jim was interested in geoponic farming, especially in the tillage of the ground for growing his vegetables.
geostrophic , more geostrophic, most geostrophic
Relating to the deflective forces produced by, or arising from, the Earth's rotation: In school, Jenifer learned about the geostrophic force that was caused by the revolution or turning of the world.
