GEOL 1403 Final
Exam test
questions and
answers
Physical geology
is the study of Earth materials, such as minerals
and rocks, as well as the processes operating
within Earth and on its surface.
Historical Geology
examines the origin and evolution of the earth and
the planets
The scientific method is
an orderly, logical approach that involves
gathering and analyzing facts about a particular
phenomenon, formulating hypotheses to explain
the phenomenon, testing the hypotheses, and
finally proposing a theory.
Hypotheses are
,tentative explanations that are formulated to
explain the observed phenomena
The atmosphere, hydrosphere, biosphere,
lithosphere, mantle, and core are:
all subsystems of Earth
The core occupies about
16 percent of the earth's volume. consist of a solid
inner core and a larger liquid outer portion
It is believed the motor that drives plate tectonics
is
convection currents of hot rock within the earth's
mantle
The asthenosphere
surrounds the lower mantle
The solid upper mantle and the overlying crust
constitute the
lithosphere
What does the rock cycle illustrates?
the interactions between Earth's internal and
external processes and how the three rock groups
are interrelated.
Igneous rocks result when
, magma of lava crystalizes, or when volcanic ejecta.
As magma cools, minerals crystallize, and is
characterized by a texture of interlocking minerals
grains
Sedimentary rocks are composed of
sediments and formed in one of three ways:
one. consolidation of mineral or rock fragment.
two. precipitation of mineral matter from solution
three. compaction of plant or animal remains
Metamorphic rocks result from
the alteration of other rocks, usually beneath the
surface, by heat, pressure, and the chemical
activity of fluids.
The theory of SEAFLOOR SPREADING suggest that
the contents move together as a single unit.
The lithosphere is divided into a series of plates
that
diverge, converge, and slide sideways past one
another.
Divergent boundaries are places where
the crust is extended, thinned, and fractured as
magma, derived from the partial melting of the
mantle, rises to the surface. And takes place along
the crest of oceanic ridges
Convergent plate boundaries takes place when
two plates collide and the leading edge of one
plate is subducted beneath the margin of the other
