FranSurface waves are a type of seismic wave that travels along the Earth's surface and can cause rocks and other surface materials to move in a rolling or shaking motion. This movement can lead to landslides, rockfalls, and other types of mass wasting events. The amplitude and frequency of surface waves can determine the extent of rock movement.

Explain the way that different seismic waves affect rock as they travel through it?
Primary (P) waves cause rock particles to vibrate in the same direction as the wave propagation, resulting in compression and expansion of the rock. Secondary (S) waves cause rock particles to move perpendicular to the wave direction, leading to shearing and deformation of the rock. Surface waves, such as Love and Rayleigh waves, cause rolling and shaking motions at the Earth's surface, resulting in damage and ground shaking.
What are three types of waves generated by earthquakes?
The three main types of waves generated by earthquakes are: Primary (P) waves: These are the fastest seismic waves and are the first to be detected. They travel through solid rock and can move through solids, liquids, and gases. Secondary (S) waves: These waves are slower than P waves and only travel through solids. They cause the most shaking and can cause the most damage to buildings. Surface waves: These waves move along the Earth's surface and are responsible for the most damage during earthquakes. They are divided into two types - Love waves and Rayleigh waves.
What are the characteristics of a P-Wave and S-Wave?
P-waves are primary seismic waves that travel the fastest and can move through both solid and liquid rock. They cause rock particles to vibrate in the same direction as the wave's movement. S-waves are secondary seismic waves that travel slower than P-waves and can only move through solid rock. They cause rock particles to move perpendicular to the direction of the wave's movement.
How do P-waves differ from S-waves?
P-waves are primary waves that can travel through solid, liquid, and gas, while S-waves are secondary waves that can only travel through solids. P-waves are faster than S-waves and have a compressional motion, while S-waves have a shearing motion.
L waves in an earthquake?
L waves, also known as Love waves, are a type of seismic wave that travels on the surface of the Earth and causes horizontal shifting of the ground during an earthquake. They move slower than P and S waves but are responsible for the majority of the damage done during an earthquake. Their movement creates a side-to-side or horizontal motion that can be particularly destructive to buildings and structures.
