This memory aid covers Memory Aid within Seismic Waves for GCSE Physics. Revise Seismic Waves in Waves for GCSE Physics with 13 exam-style questions and 15 flashcards. This topic appears less often, but it can still be a useful differentiator on mixed-topic papers. It is section 10 of 14 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.
🧠 Memory Aid
P-waves vs S-waves:
- P-waves = Primary (arrive first) = Push/pull (longitudinal) = Pass through everything (solids and liquids)
- S-waves = Secondary (arrive second) = Shake sideways (transverse) = Stopped by liquid
Earth's layers (outside to inside): "Can My Little Pony Come In?"
Crust — Mantle — (Liquid) outer core — (solid) inner core
Practice questions for Seismic Waves
What type of wave is a P-wave (primary seismic wave)?
State two differences between P-waves and S-waves in terms of how the particles move and what materials they can travel through.
Quick recall flashcards
What are S-waves?
Secondary (transverse) seismic waves - slower
What are P-waves?
Primary (longitudinal) seismic waves - fastest
