EARTH'S SHIFTING CRUST
HYDROSTATIC: Pertaining to pressure and equilibrium of liquids.
IGNEOUS ROCKS: Rocks which have cooled and solidified from a
molten state.
INSOLATION: Solar radiation received by the earth. The insolation
curve represents the combined effects on mean world-wide temperatures
of various astronomical factors, such as precession and varia-
tions of the orbit of the earth about the sun.
ISOSTASY: The definition is discussed in the text: Chapter VI.
LITHOSPHERE: The outer shell of the planet. It is composed of rocks
and the products derived from them by erosion, etc., such as gravels,
soils, and the like. The crystalline, solid lithosphere is assumed to be
between 20 and 40 miles thick. (Also called crust.)
LOAD, Negative: A deficiency of matter at a given point on the crust;
considered negative because it results in a pressure from within, as
a result of the tendency to achieve hydrostatic balance.
Positive: A local excess of mass.
MAGMA: Molten rock material within the earth. When cooled and
crystallized into solid form it yields the so-called igneous rocks (q.v.).
MASS: A measure of the amount of matter in a body.
MASS, Center of: Point at which the mass is assumed to be concen-
trated; for computational purposes.
METAMORPHIC: Altered; applied to rocks or rock strata that have
been physically changed by heat or other means.
MILLIGAL: A thickness of ten meters of granite; the effects (gravitational)
produced by such mass.
MUTATION: A sudden variation in the characteristics of a life form
as compared to those of its progenitors.
NEBULAR THEORY: A theory of the origin of the solar system, according
to which a gaseous nebula coalesced and cooled to form
centers which then further contracted to form the
compacted
planets.
OOZE: A soft deep-sea deposit composed of shells, debris, meteoric
dust, etc. Argillaceous ooze is a
clayey type.
PLANETESIMAL: A small, solid
planetary body having an individual
orbit about the sun.
PLANETESIMAL HYPOTHESIS: A theory of the origin of the solar
system supposing that the planets were formed by collision and
coalescence of planetesimals and thus have never been wholly
molten.
PLICATION: Folding into layers or strata.
PRECESSION: The wobbling of the axis of the earth, making the pole
describe a circle as the planet spins.
RADIATION, Adaptive: The production of a diversified fauna as the
result of the availability of new ecological spaces. New faunas re-
