geo-, ge- +

A mathematician specializing in, or skilled in, geometry.

The name Geometridae derives from Latin geometra which came from Greek, "geometer, earth-measurer".

This refers to 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, with 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.

1. The branch of mathematics that deals with points, lines, surfaces, and solids, and examines their properties.
2. A branch of mathematics that is concerned with the properties and relationships of points, lines, angles, curves, surfaces, and solids.
3. In nuclear medicine, any of the various arrangements between a radioactive source and a detector that affects the accuracy of counting or measurement.

1. Three-dimensional geometric surface or surfaces.
2. Earth shape or earth form.

1. Of or resembling the earth or its shape or surface configuration.
2. Pertaining to the form of the earth or the forms of its surface.

The physical and chemical interactions between the earth's surface and the natural forces acting upon it to produce landforms.

The 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.

The study of the origins of land formations.

Characterized by the study of the surface configurations of the earth; especially, the nature and evolution of present landforms, their relationships to underlying structures, and the history of geologic activity as represented by such surface features.

Someone who studies the surface configurations of the earth and the history of geologic activities as represented by such surface features.

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.
2. That branch of geology that studies the characteristics, processes that shape them, and configurations and evolutions of rocks and land forms.

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 (1880's), 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 1800's.

1. A reference ti curvatures toward the ground.
2. Growth curvature towards the ground.

1. A navigational technique in which position is determined relative to terrestrial reference points; such as, distinguished from celestial or inertial (inability or unwillingness to move or act) navigation.
2. Navigation by means of observations of terrestrial features.

Curvature towards the earth at night.

Characterized by the orientation movements in plants during darkness in response to gravity.
