Earthquakes and Volcanoes

Two pieces of Earth's crust move, break apart or slide past one another. What is the most likely event this will cause?

• Volcanic Eruption

• Formation of a Mountain

• Earthquake

• Seafloor spreading

• Fault

• Focus

• Seismic Wave

Scientists use lag time to triangulate earthquake waves. This allows them to determine the epicenter of an earthquake. What is lag time?

• The time it takes for P Waves to reach a location that is far away from the focus of an earthquake

• The distance between the earthquake epicenter and focus

• The magnitude of the seismic waves produced by an earthquake

• The difference in time it takes for P Waves and S Waves to reach a location

The instrument used to record earthquake energy.

• Seismic Meter

• Seismograph

• Richter Scale

• Triangulation

Earthquakes are measured on the Richter scale, which describes the amplitude of the seismic waves produced. On the Richter scale, a level 5 earthquake is 10x stronger than a level 4 earthquake.

Based on this information, how much stronger is a level 7 earthquake, compared to a level 5 earthquake?

• 2x stronger

• 10x stronger

• 100x stronger

• 1000x stronger

What type of tectonic plate boundary leads to the formation of volcanic arcs along coastlines, like those found in the Ring of Fire?

• Convergent

• Transform

• Divergent

• Hotspots

At mid-ocean ridges, magma rises through vents in the Earth's crust. This lava cools, creating new oceanic crust on the seafloor. What type of plate boundary does this occur at?

• Convergent

• Transform

• Divergent

• Passive

Some volcanoes form far away from tectonic plate boundaries. These volcanoes form above rising currents of magma, deep within Earth's mantle.

Volcanoes that are not associated with plate boundaries are called (a)   .

A volcano with low sloping sides that produces frequent, effusive eruptions

• Composite volcano

• Shield volcano

• Cinder cone volcano

• Caldera
