Chemical sediment

Earth science; Geology

Sediment formed by chemical precipitation from water. Example: halite precipitated as the result of the evaporation of sea water.

Break-in-bulk point

Earth science; Geology

Commonly, a transfer point on a transport route where the mode of transport (or type of carrier) changes and where large-volume shipments are reduced in size. For example, goods may be unloaded from ...

Climax vegetation

Earth science; Geology

The vegetation that would exist in an area if growth had proceeded undisturbed for an extended period. This would be the "final" collection of plant types that presumably would remain forever, or ...

Continental glaciers

Earth science; Geology

A glacier or body of compacted snow and ice, of considerable thickness and more than 50,000 square kilometres in extent, forming a continuous cover of ice and snow, spreading outward in all ...

Continental climate

Earth science; Geology

The type of climate found in the interior of the major continents in the middle, or temperate, latitudes. The climate is characterised by a great seasonal variation in temperatures, four distinct ...

Carbon-14 dating

Earth science; Geology

A form of isotope dating that relies on the 5730-year half-life of radioactive carbon-14, which decays into nitrogen-14, to determine the age of rocks in which carbon-14 is present. Carbon-14 dating ...
