Earthquakes and Volcanoes

Most of the volcanic activity on Earth occurs

• along mid-ocean ridges

• along transform plate boundaries

• at hot spots

• within the crust

High energy earthquakes occur

• away from plate boundaries

• away from divergent plate boundaries

• on convergent plate boundaries

• on transform plate boundaries

Large and explosive volcanic eruptions can change climate because

• ash and gas that erupt high into the atmosphere can reflect sunlight

• the magma that erupts is hot

• volcanic ash keeps Earth from losing its heat

• volcanic mountains block solar radiation

What is an earthquake?

• a fault at a convergent plate boundary

• a wave of water in the crust

• energy released as rocks break and move along a fault

• the elastic strain stored in rocks

Which can show the amount of energy released by an earthquake?

• A lag time graph

• The Modified Mercalli Scale

• The Moment Magnitude Scale

• The Richter Magnitude Scale

The location of an earthquake can be determined from seismic data recorded by at least

• one seismometer

• two seismometers

• three seismometers

• four seismometers

Along which type of plate boundaries do the deepest earthquakes occur?

• convergent

• divergent

• passive

• transform

The Richter scale registers the magnitude of an earthquake by determining the

• amount of energy released by the earthquake.

• amount of ground motion measured at a given distance from the earthquake.

• description of damage caused by the earthquake.

• type of seismic waves produced by the earthquake.
