Some trap it for use as an alternative fuel source. Weather occurs here, through exchanges of heat. They provide energy and facilitate fat production.

Albite - The end member of the plagioclase group of minerals. Aphanitic - Said of the texture of igneous rock in which the crystalline components are not distinguishable by the naked eye: The physical aspect of an ecosystem.

Those who actually live in a bioregion know best how to manage it. Includes the ozone layer. Humans are integral to the biologically diverse landscapes designed.

I was terrified by its fragile appearance.

Glossary of geology

Many diseases are caused by virusesbacteriaor fungi. Carbon offset A unit, equal to one ton of carbon dioxide, that individuals, companies or governments buy to reduce short-term and long-term emissions of greenhouse gases.

Anorthite - The lime rich end of the plagioclase group of minerals; Silicate of calcium and aluminium, occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. Frequent in semi-arid areas and in grasslands.

Depleted biodiversity leads to population crashes, declines in genetic variability, and extinctions. Horn Manure Preparation to introduce stirred nutrients into the soil, Horn Silica Preparation to nourish plant growth, and Compost Preparations. In this the organism is not a passive recipient of external circumstances; the relationship is interactive.

They are not free-floating like pelagic organisms are. Small paths between rows minimize soil compaction and maximize plant microclimates. The portion of the environment which a species occupies, defined in terms of the conditions under which an organism can survive, and may be affected by the presence of other competing organisms.

Also, a phase of forest biomass accumulation in the years that follow a harvest. As Leopold Kohr put it, "If something is wrong, then something is too big. In Greek mythology the Chimera--a fire-breather who was part lion, part goat, and part dragon--devastated the land until finally slain by a hero.

Azimuth is combined with altitude the distance of an object above the horizon to calculate the direction of an object as seen from a specific earthly location. A warm breeze through a relatively cool orchard, for instance.

If a person is exposed to carbon monoxide over a period, it can cause illness and even death. These interactions connect the various members of an ecosystem, and describe how energy passes from one organism to another.

The corporatization of farming, resulting in a handful of very large non-local companies owning and managing--and in some cases ruining--millions of high-yield acres. Alluvial fan - a fan-shaped deposit formed where a fast flowing stream flattens, slows, and spreads typically at the exit of a canyon onto a flatter plain.

See also Seed Saving. Symbiotic with mitochondria, as shown by biologist Lynn Margulis. A[ edit ] Abyssal plain - Flat or very gently sloping areas of the deep ocean basin floor. In the context of the UN Framework Convention on Climate Change, it is the change in climate caused by higher levels of greenhouse gases in the atmosphere due to human activities as well as natural climate changes.

For all these reasons they are as unsustainable as the civilizations that spawn them. Steps for initial bed preparation include: See also greenhouse gases and photosynthesis. Greeks and Romans once thought a "genius loci" or spirit of place inhabited every hill, grove, and stream.This glossary of ecology is a list of definitions of terms and topics in ecology and related fields.

For more specific definitions from other glossaries related to ecology, see Glossary of biology and Glossary of environmental science. Glossary Abaptation The process by which the present match between organisms and their environment, and the constraints on this match, have been determined by evolutionary forces acting on ancestors.

The use of these terms and definitions varies largely from one author to another. The list below relies on definitions used by internationally recognized organizations (e.g. ISO, SCC, SETAC), environmental agencies (e.g. Environmental Protection Agency of the USA) or research reports of large groups of scientists and projects etc.

This glossary is intended to give the meaning of key words but does not necessarily provide a legal definition or thorough description.

C. Calcareous - sediment, sedimentary rock, or soil type which is formed from or contains a high proportion of calcium carbonate in the form of calcite or aragonite.; Calcite - The crystalline form of calcium carbonate, showing trigonal symmetry and a great variety of mineral habits.

It is one of the commonest of minerals in association with both igneous.
