geo-, ge- +

1. The scientific study of the chemistry of the earth, including the rocks, sediments, and soil that constitute the solid earth and the fluids that compose the ocean, inland waters, and the atmosphere.
2. Referring to chemical reactions involving earth materials; such as, soil, rocks, and water.
3. The chemistry of the composition and alterations of the solid matter of the earth or a celestial body.

The study of the chemistry of the earth includes the study of the rocks and sediments that constitute the solid earth; as well as, the fluids of the oceans, inland waters, and atmosphere.

Geochemistry is based on a foundation of other sciences, including chemistry, geology, physics, and biology. This field of research includes the study of the movement, or flux, of chemical elements through the solids and fluids of the earth.

A reference to the chronology of the earth's history as determined by geologic events.

Someone who studies the chronology of the earth, as based on both absolute and relative methods of age determination.

1. The chronology of the earth; the measurement of geological time and the ordering of past geological events.
2. The time sequence of the earth’s history as governed by geological events.
3. The science of dating and the study of time in relation to the earth's history as revealed by geological data.

1. An extension of geometry conceived as taking time into account as the fourth dimension; the geometry of space-time.
2. Absolute geochronology, in which events are assigned (approximate) dates in relation to the present instead of to other events.
3. Measurement of geologic time, as through isotopic-radioactive decay.

One reflecting geographical rather than ecological conditions.

An organism; such as, a fly, beetle, or moth that spends the egg, or larval, stage of its life in the ground.

Living in the soil for part of a life cycle.

1. Applied to earth-movements that reduce the area of the earth’s surface covered by water (opposite of hydrocratic).
2. Of or pertaining to the predominant influence of the natural environment on man.

1. A plant with dormant parts located underground.
2. A plant having perennating organs (surviving from year to year) or renewal buds below the surface of the soil.

Earthlike, in anatomy, an enlarged lymphatic space or the dilation occurring where several lymphatic capillaries join together.

1. Relating to the geometry of curved surfaces.
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).

A strong prefabricated enclosure constructed of lightweight bars forming a grid of polygons, with no internal supports.

It is made of standardized parts that allow quick assembly and dismantling. The dome is energy efficient because it requires less building material and has less surface area, because heat loss due to wind turbulence is decreased, and because its shape minimizes air leakage.

1. The line of shortest distance between any two points on a mathematically defined surface.
2. Specifically, on the surface of the earth, a line of double curvature; which usually lies between the two normal section lines determined by the two points.

Someone who specializes in the field of geodesy.
