The Earth's Shifting Crust by Charles Hapgood - wire of information

GLOSSARY
ANOMALY, Positive: An excess of mass at a point on the crust, as com-
pared with the average distribution of mass.
Negative: A similar but opposite condition, in which there is a
local deficiency of mass.
ANTICLINE: An archlike folding of rocks or rock strata so that the
lower beds or strata are enclosed in the upper.
ARCHAEOCYATHIDAE: A fossil sponge, at one time supposed to be
a fossil coral.
ASTHENOSPHERE: A layer of material below the crust; assumed to
be weak because of heat and pressure.
BASEMENT ROCKS: Rocks of great obscurity and complexity lying
beneath the upper rock layers; thus, the lowermost rocks of the
known series.
CENTRIFUGAL FORCE: The force tending to throw a body away
from the center, in a straight-line direction of flight.
DECIDUOUS TREES: Trees having seasonally falling foliage (oak,
elm, etc.) as contrasted with evergreens, having constantly renewed
foliage (pine, etc.).
DIASTROPHISM: The process, or processes, by which major features
of the crust are formed through deformation, such as faults, plateaus,
etc.
ECOLOGICAL: Pertaining to the mutual relationship between organisms
and their environment. An ecology is the place-relationship of
life forms in their environment.
EPEIROGENESIS (EPEIROGENY): A grander form of diastrophism,
forming the broader features of crustal relief, such as continents,
ocean beds, etc.
EPICONTINENTAL: Pertaining to regions along the continental shelf.
EUSTATIC: Pertaining to a land area which has not undergone eleva-
tion or depression.
GEOID: The figure of the earth (an oblate sphere) with the average sea
level conceived of as extending throughout the continents.
GEOSYNCLINE: A great downward flexing of the crust.
GRAVITY, Center of: An imaginary point at which, for reasons of
computation, the entire weight or mass of a body is imagined to be
concentrated.
HORSE LATITUDES: A belt in the neighborhood of 30 N. or S. Lat,
characterized by high pressure, calms, and baffling winds.
