Transcript crust, mantle, outer core, inner core

Unit 2
Review
Rigid, upper part of Earth’s mantle
and the crust
(lithosphere, outer core, inner core)
Lithosphere
When plates move apart, new crust
forms to fill in gaps between the
plates
( sliding plates, separating plates,
colliding plates)
Separating Plates
Form when forces inside Earth push
up the crust
( fault-block mountains, folded
mountains, upwarped mountains)
Upwarped mountains
Appalachian Mountains are a type of
these
( fault-block mountains, folded
mountains, upwarped mountains)
Folded mountains
Which of the following words is
not associated to an earthquake:
(fault, rift, P-waves, focus)
rift
Earthquake waves are called
( fault, epicenter, seismic waves)
Seismic waves
Largest of Earth’s layers; solid,
but flows like putty ( crust,
mantle, outer core, inner core)
Mantle
A measure of the energy
released by an earthquake
(fault, seismograph, P-waves,
magnitude)
Magnitude
Solid, innermost layer of Earth’s
interior ( crust, mantle, outer
core, inner core)
Inner core
Leaves, twigs, and other organic
material that eventually can be
changed to humus
(leaching, litter, soil)
litter
Broad, flat, buildup of basaltic
layers, gently sloping sides
(shield volcano, cinder cone
volcano, composite volcano)
Shield volcano
Minerals in rocks dissolve or
change to other minerals
(mechanical weathering,
chemical weathering, climate)
Chemical weathering
Helps reduce erosion on steep
slopes
(no-till farming, contour farming,
terracing)
terracing
Bowl-shaped part of a volcano; lava
often collects here before flowing
down the slope
( vent, crater, magma chamber, pipe)
Crater
Piling yard wastes where they
can decompose gradually
(leaching, litter, composting)
composting
Which force creates this type of
fault
( compression, extension, shear)
Shear
Large bodies of magma; caused
the Hawaiian Islands to form
(fault, rift, hot spots, focus)
Hot spots
Occurs when rocks are broken
apart by PHYSICAL processes
(mechanical weathering,
chemical weathering, climate)
Mechanical weathering
Mixture of weathered rock,
decayed organic matter, mineral
fragments, water, and air
(oxidation, weathering, soil)
soil
The removal of minerals that
have been dissolved in water
(leaching, litter, chemical
weathering)
leaching
If the resources on Earth became
scarce and the environment loses its
ability to support the population we
have reached our…
(population, pollutants, carrying
capacity)
Carrying capacity
Large fractures in rocks along
which movement occurs
( plates, faults, epicenter)
Faults
Tephra forms a small cone of
volcanic material; usually produces a
short, powerful eruption
(shield volcano, cinder cone volcano,
composite volcano)
Cinder cone volcano
