• core
• crust
• mantle
• outer core

The huge pieces of the earth's crust are called ____________________________. 

• crust
• plates
• directions
• seismos

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

Waves move out through the ground from the ..........

• rift
• hypocenter
• epicenter
• fault line

NGSS.MS-PS4-2

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

NGSS.MS-ESS3-2

The Richter scale measures:

• the amount of radon gas released
• the movement of plates
• the strength of an earthquake
• the weight of tectonic plates

The Modified Mercalli scale rates the amount of damage from an earthquake

• true
• false

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

• P waves
• S waves

Tags

NGSS.MS-PS4-1

What do S (secondary) waves do during an earthquake?

• Shake the ground
• Cause eruptions
• Open cracks in the earth's surface
• Create loud noises

An earthquake scored high on the Richter scale but low on the Mercalli scale. Why?

• it probably happened in an area with no people
• it was a fast earthquake
• because it damaged a lot
• impossible to tell
