⭐ https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Seismic Waves 2. P-Waves (Primary Waves) 3. S-Waves (Secondary Waves) 4. Wave Behaviour Reflection and refraction at boundaries between layers. 5. Detecting Seismic Waves Use of seismometers by seismologists. Analysis of travel times and detection locations. How S-wave shadow zones provide evidence for a liquid outer core. How P-wave paths and shadow zones refine the model of Earth's structure. ** EXAM BOARD INFO ** AQA - Separate/triple science and higher tier only IGCSE Edexcel - Not in your course Edexcel - Don't need to know the details about how it was used to discover the internal structure of the earth OCR 21st Century - Don't need to know the details, but the general idea of using waves to discover internal structure of earth is helpful OCR Gateway - Not in your course ** CHAPTERS ** 0:00 Introduction to Seismic Waves 0:28 P-Waves vs S-Waves Properties 0:47 Using Seismic Waves to Study Earth's Structure 1:25 Wave Behaviour at Boundaries 2:49 P-Wave Paths Through Earth 3:00 S-Wave Paths Through Earth (S-Wave Shadow Zone) 3:34 P-Wave Shadow Zone 4:00 Summary: How Seismic Waves Reveal Earth's Structure ** PLAYLISTS **    • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • Alevel Biology   #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel #IB #AP
