Question

after an earthquake, which type of seismic wave arrives last at a seismometer? a. p and s waves b. p waves c. s waves d. l waves

Explanation:

• P waves (Primary waves): They are compressional waves and the fastest - moving seismic waves. They can travel through solids, liquids, and gases.
• S waves (Secondary waves): These are shear waves. They are slower than P waves and can only travel through solids.
• L waves (Surface waves): They are the slowest - moving seismic waves. They travel along the Earth's surface. Since they have the slowest speed among the three types of seismic waves (P, S, and L), they will be the last to arrive at a seismometer.

Answer:

D. L waves
