Earthquakes and Volcanoes Review

Sometimes magma does not reach the surface and cools underground. According to geologists, why does magma force its way to the surface?

• Magma is less dense than solid rock.

• Magma is denser than solid rock.

• Metamorphic rock is less dense than igneous rock.

• Magma is cooler than solid rock.

Which of the following can result when underground water is heated at a hot spot?

• Metamorphism

• Geysers

• Salt domes

• Karst topography

What is the fewest number of seismographic stations that must record the arrival time of P and S waves in order for the epicenter of an earthquake to be located?

• 2

• 3

• 5

• 10

Primary waves and secondary waves are generated at the same time, but primary waves are recorded first because they –

• travel a shorter route.

• are smaller.

• travel faster.

• do not travel through water.

• ocean basins.

• intercontinental plains.

• Earth's largest rivers.

As landmasses drifted over the Earth from 180 million years ago to the present day, one significant change that occurred was the -

• increase in overall landmass size.

• decrease in the number of transverse faults.

• increase in the number of trenches.

• decrease in the number of mid-ocean ridges.

The folding and faulting found in the rocks of the Blue Ridge Mountains of Virginia were created by —

• a collision of tectonic plates.

• the waves of a prehistoric ocean.

• a rifting plate boundary.

• heating and cooling of the prehistoric atmosphere.
