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 ...
Sedimentary rock composed of calcium carbonate (calcium carbonate) formed by deposits of seashells and marine animal skeletons. Limestone is often added to cement and other construction materials, including blocks and facings.
Industry:Biology
A mobile chunk of primarily basaltic lithosphere floating on the asthenosphere below it. The plates are about 75 kilometers thick. Volcanism at the mid-ocean ridges produced them 700 million years ago. See Continental Plate.
Industry:Biology
One that arrives when the moon is in its first or last quarter. Because the sun and moon stand at right angles to each other, their tidal pulls partially nullify each other, resulting in a lesser tide. Contrast with Spring Tide.
Industry:Biology
A diagram showing the flow of energy through the trophic levels of a food chain or web. About 10% of the usable energy at one trophic level makes it to the next. Many small organisms are needed to feed relatively few larger ones.
Industry:Biology
Sodium chloride. Also, compounds produced when an acid's hydrogen atom is replaced by a metal atom. Also, what unscrupulous fast food restaurants do with french fries and potato chips in order to sell more drinks to thirsty customers.
Industry:Biology
Marshy land covered by shrugs and mosses. Their acidic soils accumulate peat, the thick, carbonized vegetable tissue decomposed in water. The words "bogeyman" and "heathen" derive from outcasts who inhabited these poorly drained areas.
Industry:Biology
What homeowners need when their homes have been constructed on slipping hillsides, canyon floors, eroding coastlines, floodplains, and swathes of chaparral by developers working in complete disregard of the forces and cycles of nature.
Industry:Biology
A surface that blocks water from going into the soil: highways, streets, parking lots. In urban areas the resulting storm runoffs spread pollution and waste, erode whatever soils they reach, and threaten communities with flash flooding.
Industry:Biology
Originally a Darwinian hypothesis twisted around by philosopher Herbert Spencer to justify any desired might-makes-right form of social injustice as natural and inevitable. Very often “fittest” means the most cooperative--see Mutualism.
Industry:Biology
A type of chemical weathering in which carbonic acid (carbon dioxide dissolved in rainwater) reacts with the magnesium, potassium, sodium, or calcium in rocks like limestone and feldspar and thereby dissolves them, sometimes forming caves.
