Love and Rayleigh waves are

Question

Accepted Answer

Love and Rayleigh waves are **Surface Waves**.

Here's why:

*   **Why Option 3 is correct:** Love waves and Rayleigh waves are types of seismic waves that travel along the Earth's surface. They are generated by earthquakes and are confined to the uppermost layers of the Earth's crust. Their amplitude decreases with depth, meaning they are most prominent at the surface. This characteristic defines them as surface waves.

*   **Why Option 1 is incorrect:** Primary waves (P-waves) are body waves, meaning they travel through the interior of the Earth. They are compressional waves and are the fastest type of seismic wave. Love and Rayleigh waves are not P-waves.

*   **Why Option 2 is incorrect:** Secondary waves (S-waves) are also body waves that travel through the Earth's interior. They are shear waves and cannot travel through liquids. Love and Rayleigh waves are not S-waves. They are fundamentally different in their mode of propagation and location.

*   **Why Option 4 is incorrect:** Option 3 is correct, therefore this option is incorrect.
