geo-, ge- +

(Greek: earth, land, soil; world; Gaia (Greek), Gaea (Latin), "earth goddess")

geometrician (s) (noun), geometricians (pl)
A mathematician specializing in geometry: Janet's math teacher was a real geometrician who was totally skilled in geometry and motivated his students with success!
Geometridae (all) (proper noun)
A big family of heterocerous lepidopterous insects or moths: The Geometridae include the geometrid moth whose larvae are called "measuring worms".
The name Geometridae is derived from Latin geometra which came from Greek, "geometer, earth-measurer".

The process of locomotion of the larvae or caterpillars, which don't have the prolegs of other Lepidopteran caterpillars in the middle portion of the body, involves only two or three pairs at each end.

Equipped with external body parts that project from the body at both ends of the body, a caterpillar will grip with its front legs and draw up the hind end, then it will clasp with the hind end (prolegs or the fleshy, stumpy legs on the hind region of caterpillars) and reach out for a new front attachment all of which give the impression that it is measuring its journey.

The caterpillars are accordingly called "loopers, spanworms", or "inchworms" because of their characteristic looping movements.

geometry, counting geometry (s) (noun); geometries; counting geometries (pl)
1. The branch of mathematics that deals with points, lines, surfaces, and solids, and examines their properties: Geometry is a subject taught in school which is concerned with the features and relationships of points, lines, angles, curves, surfaces, and solids.
2. In nuclear medicine, any of the various arrangements between a radioactive source and a detector that affects the accuracy of counting or measurement: Counting geometry is a branch of algebraic geometry which deals with assessing the number of clarifications to geometric problems.
geomorph (s) (noun), geomorphs (pl)
A three-dimensional geometric surface or surfaces: The students analyzed the Earth's form as being an example of a geomorph.
geomorphic (adjective) (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.
geomorphic process (s) (noun), geomorphic processes (pl)
The physical and chemical interactions between the Earth's surface and the natural forces acting upon it to produce landforms: The geomorphic processes are determined by such natural environmental variables as geology, climate, vegetation and baselevel, to say nothing of human interference. The nature of the process and the rate at which it operates will be influenced by a change in any of these variables.

geomorphogeny (s) (noun) (no pl)
The study of the origins of land formations: Greg wanted to study geomorphogeny an d learn more about the surface features of the Earth and how they emerged from the beginning.
geomorphological (adjective), more geomorphological, most geomorphological
Pertaining to the study of the surface configurations of the Earth: The geomorphological evolution of present landforms shows the relationships to underlying structures, and the history of geologic activity as represented by such surface features.
geomorphologist (s) (noun), geomorphologists (pl)
Someone who studies the surface configurations of the Earth and the history of geologic activities as represented by such surface features: Dr. Crawford was Tim's father who was a geomorphologist and did research on the origins of the geological aspects of the Earth.
geomorphology (s) (noun), geomorphologies (pl)
1. The study of the classification, description, nature, origin, and development of present landforms and their relationships to underlying structures, and of the history of geologic changes as recorded by these surface features: Geomorphology is that branch of geology that deals withs the characteristics, processes that shape them, and configurations and evolutions of rocks and landforms.

Geomorphologists seek to understand landform history and dynamics, and predict future changes through a combination of field observations, physical experiments, and numerical modeling.

The discipline is practiced within geology, geography, archaeology, and civil and environmental engineering. Early studies in geomorphology are the foundations for pedology, one of two main branches of soil science.

Geomorphology is the science of landforms. It is the science that provides us with a closer look at the Earth's surface and the processes that have formed them.

Although geomorphology is concerned with landforms that currently exist, past landforms and events must be examined in order to fully understand how they came about.

Although the term geomorphology is a relatively new term (1880s), the examination of the forces of nature that have impacted the Earth's surface extends back into the days of early Greek and Roman philosophers, such as Aristotle and Seneca.

Their writings included ideas on stream erosion, earthquakes, and other deformations. Though these early philosophers speculated on the ideas of landscape evolution, these processes and thoughts were not fully examined until just before the 1800s.

geonastic (adjective) (not comparable)
Pertaining to the movement of vegetation growing on the ground: Two examples of geonastic plants that thrive on the ground are the pumpkin and sweet potato, which are both creepers.
geonasty (s) (noun) (no pl)
The movement of a plant towards gravity or towards the ground: The condition of geonasty can be described as the growth of certain creepers that thrive close to the soil.
geonavigation (s) (noun), geonavigations (pl)
A guidance or piloting by means of observations of terrestrial features: Geonavigation is a technique in which a position is determined relative to terrestrial reference points, such as distinguished from celestial or inertial (inability or unwillingness to move or act) navigation.
geonyctinastic (adjective) (not comparable)
Relating to a curvature towards the ground at night: The sunflower is geonyctinastic in that the flower droops or moves downwards when it is night and while still in growth.
geonyctitropic (adjective) (not comparable)
Characterized by the orientation movements in plants during darkness in response to gravity: One example of a geonyctitropic plant is cannabis in which the leaves move downward from a horizontal position during the day to a more vertical down-facing position at night.
