• Q10

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.

• Q11

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.

• Q12

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.

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 migrated

• Q20

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.
