Which of the following statements about weathering is FALSE?
Heat and heavy rainfall increase the rate of chemical weathering.
Rocks of different compositions weather at different rates.
The longer a rock is exposed at the surface, the more weathered it becomes.
The presence of soil slows down the weathering of the underlying bedrock.300sS11ES-IIa-22EditDelete

Erosion at both locations A and B
Deposition at location A, erosion at location B
Deposition at both locations A and B
Erosion at location A, deposition at location B300sS11ES-IIa-22EditDelete
Which weathering process is most common in a hot, dry environment?
Heat flow from Earth’s interior to its surface and atmosphere _________.
roughly the same everywhere on Earth
is associated with plate tectonics
varies randomly from place to place on Earth300sS11ES-IIb-c-23EditDelete
Over time, Earth’s interior is __________.
cooling off during some periods of Earth history and warming up during others
gaining and losing the same amount of thermal energy each year300sS11ES-IIb-c-23EditDelete
Which of the following is NOT a major process that has contributed to Earth’s internal heat?
The heat released as iron crystallized to form the inner core.
The heat from radioactivity of radioactive isotopes of U, Th and K.
The heat from the sun since the beginning of Earth history.
The heat released by colliding particles during the formation of the Earth.300sS11ES-IIb-c-23EditDelete
Which of the following locations describes one example of a place where igneous rocks are forming?
Within the crust below an active volcano
Everywhere beneath the earth's surface
In a streambed near a volcano
On the surface of the sea floor300sS11ES-IIc-25EditDelete
Formation of magma generally begins __________.
along the surface of a rock body
at the centers of mineral crystals
in the center of a rock body
at the junctions between different mineral grains300sS11ES-IIc-25EditDelete
Which of the following statements best describes magmatic differentiation?
The process by which the same igneous rock may produce different magma compositions upon melting.
Heavier crystals float on the top of the magma in the magma chamber producing a layered igneous rock upon complete solidification.
The process by which the same magma may produce different composition igneous rocks.
Crystal settling may produce different melting conditions for a rock in different plate tectonic scenarios.300sS11ES-IIc-25EditDelete
Why can studying the mineral assemblage in a metamorphic rock give information about the temperature and pressure conditions under which it formed?
All rocks formed under the same pressure and temperature conditions have the same mineral composition, regardless of the original parent rock composition.
As pressure and temperature change, unstable minerals react to form minerals that are stable under the new conditions.
Minerals formed under high temperature and pressure contain inclusions that preserve the metamorphic history of the rock.
Some minerals are produced spontaneously under specific temperature and pressure conditions.300sS11ES-IIc-d-26EditDelete
A geologist concludes that a particular metamorphic rock formed at high pressure. Which feature of the rock most likely led to this conclusion?
Its parent rock contained large sediments.
It contains dense minerals.
It was found in close association with intrusive igneous rock.
Its layers have been pulled and lengthened.300sS11ES-IIc-d-26EditDelete
What happened to the temperature and pressure if the rocks are buried down deep?
They intermittently change
They remain constant300sS11ES-IIc-d-26EditDelete
The most common stress on rocks at convergent plate boundaries is __________.
The stress force that causes a mass of rock to pull apart or twist in opposite directions is called__________.
Because stress is a measure of force, it __________.
adds energy to rock
makes a rock harder
adds volume to rock
takes energy out of rock300sS11ES-IId-27EditDelete
In seafloor spreading, molten material rises from the mantle and erupts __________.
at the north and south poles
along mid-ocean ridges
in deep ocean trenches
along the edges of all the continents300sS11ES-IIf-32EditDelete
Who among of the following scientist was credited with seafloor spreading?
Dennis Lieding, a Libertyville Social Studies teacher
Harry Hess, an American geologist
Alfred Wegener, German scientist
J. Tuzo Wilson, a Canadian scientist300sS11ES-IIf-32EditDelete
One remarkable realization associated with the discovery of seafloor spreading was that__________.
the crust of the continents is denser than the crust of the ocean
mountains are denser than then mantle
the crust of the oceans is very young relative to the continents
the rotational poles of the Earth have migrated300sS11ES-IIf-32EditDelete
How is an ocean basin formed?
A continental plate is pulled apart and seafloor spreading creates ocean lithosphere in the gap left between the pieces.
Heat and volcanism from Earth’s mantle can cause granitic continental crust to change into basaltic ocean crust.
All the ocean basins were formed when Earth’s crust first formed, so there are no new oceans.
Continental lithosphere becomes so dense that it sinks.300sS11ES-IIf-33EditDelete
