The core of Earth is probably composed of
silicate minerals.
aluminum oxides.
iron and nickel.
calcium magnesium sulfate.
Earth's layer with the most brittle behavior is the
mantle.
crust.
inner core.
outer core.
The outer core
has a plastic-like flow.
spins, which produces Earth's magnetic field.
is solid as a rock.
transmits S-waves.
The lithosphere rides on top of the asthenosphere. Lithospheric movement causes
earthquakes, volcanic activity, and mountain building activity.
the subduction of continental crust under oceanic crust.
hot-spot activity as found in Hawaii.
widespread destruction.
The lithosphere includes
continental and oceanic crust.
the crust and the upper part of the mantle.
part of the mantle and the crust.
all of the above
The inner core is solid because
it is composed of iron and nickel.
the surrounding outer layers act as a blanket to insulate the core.
pressure from the weight of the surrounding layers prevents the inner core from melting.
None of these, for the inner core is not solid, but liquid.
The mantle is composed of
iron and nickel.
iron, magnesium, silicon
half liquid and half rocky material.
solid rock.
The lithosphere floats atop the
mantle.
crust.
asthenosphere.
mohorovicic.
Isostasy is
the positioning of the crust in response to the buoyant force and gravity.
the buoyant force exerted on the mantle by oceanic crust.
the buoyant force exerted on the mantle by continental crust.
the force of gravity acting on the crust.
Continental crust is very buoyant compared with oceanic crust because continental crust is
predominantly composed of basaltic rock that contains many air bubbles from successive lava flows.
predominantly composed of granitic rocks, whereas oceanic crust is composed of basaltic rocks.
thinner than the oceanic crust, forming a thin upper skin on the oceanic crust below.
very young and fresh.
The two most abundant elements in Earth's crust are
silicates and carbonates.
silicon and oxygen.
oxygen and aluminum.
quartz and feldspar.
Based on its abundance in Earth's crust, most rocks contain a mineral composed of the elements oxygen and
carbon.
silicon.
iron.
sulfur.
Color is not a reliable means for mineral identification because
minerals come in a variety of colors
minerals can weather and change color.
a mineral's powdered color is different than its solid color.
minerals are always the same color
Magma that solidifies before reaching Earth's surface is called
intrusive igneous rock.
plutonic rock.
a pluton.
all of the above
Magma that solidifies before reaching Earth's surface is called

The majority of surface rocks are
extrusive.
sedimentary.
intrusive.
metamorphic.
The property many metamorphic rocks exhibit by flat or elongated mineral grains in parallel layers is called
schist.
cleavage.
foliation.
lithification.
Metamorphism caused by the close proximity of a magma source is called
contact metamorphism.
dynamic metamorphism.
regional metamorphism.
none of the above
Rocks altered by heat and pressure beneath Earth's surface are
intrusive igneous rocks.
extrusive sedimentary rocks.
metamorphic rocks.
igneous rocks.
A sedimentary rock can turn into an igneous rock by
compaction and cementation.
compaction.
melting and cooling.
weathering and lithification.
Rocks are grouped into three classes depending on how the rock was
formed.
located.
discovered.
shaped.
