GEOLOGY

Detailed explanation-1: -Because it rolls, it moves the ground up and down, and forward and backward in the direction that the wave is moving. Most of the shaking felt from an earthquake is due to the Rayleigh wave, which can be much larger than the other waves.

Detailed explanation-2: -In physics, a surface wave is a mechanical wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Gravity waves can also occur within liquids, at the interface between two fluids with different densities.

Detailed explanation-3: -A seismic wave that travels across the surface of the Earth as opposed to through it. Surface waves usually have larger amplitudes and longer wavelengths than body waves, and they travel more slowly than body waves do.

Detailed explanation-4: -In a surface wave, particles of the medium move up and down as well as back and forth. This gives them an overall circular motion.

Detailed explanation-5: -Surface waves travel along the Earth’s surface. Two examples of surface waves are Rayleigh waves and Love waves.
