पृथ्वी की आंतरिक संरचना की समझ प्राप्त करने के लिए भूकंप सर्वेक्षण का क्या महत्व है? विस्तार से विश्लेषण कीजिए। / To what extent does seismic investigation contribute to our understanding of the Earth's interior structure? Analyze its significance in detail.
Introduction
Seismic waves have helped us significantly in understanding the earth's interior.

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)
