While researching a topic, a student has taken thefollowing notes:• Earthquakes start at a point called a “focus” andspread out from there as seismic waves.• The two types of seismic waves that travel beneathEarth’s surface are primary waves (P waves) andsecondary waves (S waves).• P waves travel more quickly beneath Earth’ssurface than do S waves.• P waves compress and expand the ground, causingit to move backward and forward.• S waves cause the ground to move from sideto side.The student wants to emphasize a similarity betweenP waves and S waves. Which choice most effectivelyuses relevant information from the notes toaccomplish this goal?A) P waves and S waves both travel beneath Earth’ssurface, causing the ground to move.B) P waves travel away from an earthquake’sstarting point at a higher rate of speed than doS waves.C) Spreading out from the focus of an earthquake,P waves move the ground backward andforward.D) Although P waves and S waves start at the samepoint, they behave very differently.
