Terrapsychology is a word coined by Craig Chalquist to describe deep, systematic, trans-empirical approaches to encountering the presence, soul, or "voice" of places and things: what the ancients knew as their resident genius loci or indwelling spirit. This perspective emerged from sustained ...
Sudden depopulation as a result of resource depletion. A crash can often be seen a long way off in communities on a direct course to disaster through overuse of food and other vital supplies.
Industry:Biology
Unprocessed carbon compounds added to an aquatic environment. Example: straw or leaves blown into a pond. Microorganisms eventually break it down into FPOM (Fine Particulate Organic Matter).
Industry:Biology
A plant whose presence and health give clues about soil quality. Moss sometimes means a lot of acid in the soil, for example, although to a seasoned eye, most plants can serve as indicators.
Industry:Biology
N. L. Bowen's generally accepted hypothesis that how rocks crystalize from magma--whether they turn out mafic, intermediate, or felsic--depends on the magma's composition and temperature.
Industry:Biology
An animal with a backbone. Most large animals are vertebrates. They probably evolved from a wormlike ancestor that turned upside down (upside-down catfish do this today). See Invertebrate.
Industry:Biology
The maximum poplation an ecosystem can support of a given species. An ongoing debate focuses on whether the Earth's carrying capacity for humans has already been exceeded or shortly will be.
Industry:Biology
A roughly diamond-shaped map projection whose distances are accurate only along the parallels and the central meridian. Distortion increases near the poles and away from the center bulge.
Industry:Biology
A surface deposit of heavy mineral particles like gold or platinum. In the mid-1800s, placer mining by pick and pan gave way to powerful hydraulic hoses that washed away entire hillsides.
Industry:Biology
Segments cut from parent plants for growing elsewhere. Cuttings grow best from sunside shoots or branches with two nodes each. They are planted with the top bud just clear of the soil.
Industry:Biology
The accumulation of marine sediments at the edges of a continent, building up in some cases into entire coastal mountain ranges. See Plate Tectonics for more about what causes accretion.
