Main Body
as - P waves travel through all medium
S waves travel through only solid
[e.g. Conrad discontinuity, Repti discontinuity etc.
Significance
Thus the seismic analysis has an important role to play in the understanding of the earth's interior.

Diagram
Two diagrams showing Earth's internal structure - upper diagram shows layers labeled mantle, core, crust; lower diagram shows detailed cross-section with labeled layers (crust, mantle, outer core, inner core, with S waves and P waves paths indicated)
- Clear explanation of P and S wave propagation
- Comprehensive significance section
- Specific examples of discontinuities
- Links to practical applications (earthquake detection, resource identification)
- Good use of diagrams for visualization
