Exploring Seismic Waves and Earthquake Dynamics

The video explains seismic waves generated by earthquakes, detailing their types and characteristics. It covers body waves, including P and S waves, and surface waves, such as Love and Rayleigh waves. The video also discusses how these waves help scientists understand earthquakes and Earth's structure.

What instrument is used by scientists to record seismic waves?

• Seismometer

• Seismograph

• Barometer

• Thermometer

What type of seismic waves are first to arrive at recording stations?

• S waves

• Rayleigh waves

• P waves

• Love waves

Through which mediums can P waves travel?

• Liquids only

• Solids only

• Solids, liquids, and gases

• Gases only

What motion do S waves cause in the ground?

• Shearing or crosswise

• Vertical

• Horizontal

• Circular

Why are S waves called secondary waves?

• They are less important

• They arrive before P waves

• They only move vertically

• They arrive after P waves

Which waves are more destructive, body waves or surface waves?

• Both equally

• Surface waves

• Body waves

• Neither

What is the primary effect of Love waves?

• Horizontal motion

• Elliptical motion

• Vertical shaking

• Compression and expansion
