Earthquakes & Seismic Waves

What is a weakness or crack/break in the lithosphere that can shift and create an earthquake?

• Earthquake
• Epicenter
• Fault
• Focus

Which type of wave travels the fastest and is the first to arrive after an earthquake occurs?

• P- Wave

• Rayleigh Wave

• S- Wave

• Shear Wave

Which seismic wave compresses and stretches rock materials as it passes through the Earth's interior?

• Body Waves

• P- Waves

• S- Waves

• Surface Waves

Which seismic waves cause particles of rock material to move at right angles to the direction in which the waves are traveling?

• Body Waves

• P- Waves

• S- Waves

• Surface Waves

What is the shaking of the Earth’s crust caused by a sudden release of energy?

• Earthquake
• Epicenter
• Fault
• Plate

Which of the two waves is the most destructive wave?

Rank the seismic waves in order of appearance when an earthquake first occurs as measured by a seismograph.

• S waves, P waves, then surface waves

• P waves, S waves, then surface waves

• S and P waves at the same time, then surface waves

• Surface waves, then S and P waves at the same time

An instrument that detects and measures earthquakes is a 

• seismogram
• focus seismic map
