26.3.1. Nature and Motion

Try these first

1. 1.

   What type of motion do Rayleigh waves exhibit?

   Hint

   Think about ocean waves.

2. 2.

   Which type of waves are Rayleigh waves?

   Hint

   Consider what type of waves travel along the Earth's surface.

3. 3.

   Rayleigh waves travel in which type of motion?

   • Straight lines
   • Retrograde elliptical paths
   • Random motion

   Hint

   Think of how waves on water might move.

4. 4.

   True or False: Rayleigh waves can only travel through solid rock.

   • True
   • False

   Hint

   Consider where waves move in relation to the Earth's surface.

5. 5.

   Analyze a city with varied soil types and predict how Rayleigh wave propagation might differ across it during an earthquake.

   Hint

   Think about how soil characteristics influence wave behavior.

6. 6.

   Design a foundation for a tall structure in an area prone to Rayleigh wave impact. What factors would you need to consider?

   Hint

   Consider how the foundation's characteristics relate to wave impact.
