Tiny organic and inorganic (often clay) particles found in a soil. They carry a negative electrical charge, have much to do with the soil's chemistry, and serve as the primary sites for cation ...

An element variant in which the number of neutrons does not equal the number of protons. U-235 has the same number of protons, but not neutrons, as U-238, but U-238 will not fission itself into an ...

Liquefaction

Biology; Ecology

The brief conversion of saturated soil into a structureless mass that flows like fluid. When earthquakes trigger it, walls, dams, buildings, and foundations are liable to collapse. Frequent near ...

Buddhist theory of mutual causality, which in practise means the interdependency of personal and social activity. Joanna Macy links this to a sense of environmental responsibility: consciousness (not ...

Angle of repose

Biology; Ecology

The steepest angle that slope, rock, or detritus material settles into without toppling. Builders of flood-prone roads and sliding hillside homes in California ignore the angle of repose so often ...

Carbonation

Biology; Ecology

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 ...
