Introduction

Seismic waves have helped us significantly in understanding the earth's interior.

11 words

Main Body

Seismic waves: P-waves (3); long-lived; S-waves: 4-5 km/s (transverse). Body waves

From P-waves:

1. Inner wave (solid word element) - The closer the interior, lower the need of wave and the i-waves directly opposite mark the frost

2. Helps in determining interior densities due to earth P-wave shadow zone by i-waves can travel through solid, liquid

From S-waves:

1. Interior is non-homogenous as to extent of refraction

2. Mantle (test) is also non-homogenous so refraction is away from the core

3. The core is keyed (outer core)
