05 Earthquakes (all)

The epicenter of an earthquake is

• The point below the surface where rock begins to break and the first motion occurs
• The seismic station closest to the earthquake
• The place where the greatest damage occurs
• The point on the surface directly above the focus

Which travels fastest, always being the first detected by seismic stations?

• P waves

• S waves

• Surface waves

• Body waves

Liquefaction is when...

• the soil behaves like liquid
• the ground becomes liquid
• magma rises to the surface
• buildings are damaged, crumbling like liquid

An instrument that detects and measures earthquakes is a 

• seismogram
• focus seismic map
• focus
• seismograph 

Earthquakes under the water can cause _________________________________.

• tornadoes
• tsunamis
• lightening
• hailstorms

A tracing of earthquake motion that is created by a seismograph. This can be on a huge sheet of paper, shows P-waves 

• Seimogram 
• Seismic wave
• Carrollton 
• Deformed 

Second waves to arrive that cause earthquakes

• P waves
• S waves
• Surface waves

Smaller earthquakes that occur in the same area after a larger earthquake has occurred.

• aftershock
• liquefaction
• tsunami

The outside layer of the earth is called ______________________.

• core
• crust
• mantle
• outer core

This famous transform fault is located in the western United States creates significant earthquake activity for California

• New Madrid
• Denali Fault
• Ramapo Seismic Zone
• San Andreas
