Quick Check - Lesson 2 & 2.1 Earthquake Articles

Vibrations in the earth caused by a sudden release of energy, usually as a result of the movement of rocks along a fault.

• volcano

• earthquake

• tsunami

• tornado

What percentage of earthquakes are caused by the release of energy from movement along faults?

• 10%

• 80%

• 5%

• 90%

NGSS.MS-PS3-5

A measure of the DAMAGE done by an earthquake that is determined on the bases of the earthquake’s effect on people, structure, and the natural environment.

• magnitude

• intensity

• Mercalli Scale

• Richter Scale or Moment Magnitude Scale

What is the scale used to measure magnitude?

• Mercalli Scale

• Power Scale

• Richter Scale or Moment Magnitude Scale

• Seismograph

What would be considered a great earthquake with an extremely high magnitude?

• 5.9 or higher

• VIII

• XII

• 8.0 or higher

NGSS.HS-ESS1-5

What are the factors that affect intensity?

• How far the location is from the fault where the earthquake occurred.

• The depth at which the earthquake occurred.

• The population density of the area

• The type of building construction in the area.

• How much weight Dwayne "The Rock" Johnson can lift!

What are other factors that affect the intensity of an earthquake?

• The duration (length) of the shaking

• The rotation of the Earth on its axis.

• The type of surface material the building sits on (like dirt or rock).

• Magnitude can affect intensity because an earthquake of a higher magnitude releases more energy than an earthquake of lower magnitude.
