S-wave

The video explains the different types of seismic waves generated during an earthquake. It highlights the distinction between P waves, which are longitudinal and travel faster, and S waves, which are lateral and arrive later. The P waves are compared to sound waves in air, while S waves are described as causing lateral ground movement.

What is the primary focus of the initial discussion on earthquake waves?

• The speed of sound waves in air

• The movement of the ground during an earthquake

• The history of earthquake studies

• The impact of earthquakes on buildings

How do lateral movements differ from longitudinal P waves?

• Lateral movements are faster than P waves

• Lateral movements occur in the same direction as P waves

• Lateral movements are perpendicular to the direction of P waves

• Lateral movements are slower than S waves

Which type of wave is similar to sound waves in air?

• P waves

• Surface waves

• S waves

• Lateral waves

What is a key characteristic of S waves in relation to P waves?

• S waves arrive after P waves

• S waves are more destructive than P waves

• S waves arrive before P waves

• S waves travel faster than P waves

Through what medium do P waves propagate more quickly?

• Water

• Air

• Ground

• Metal
