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
