KS3 Geography — Inside Earth — Extension Pack

🌋 Stretch high achievers further with four ready-to-use enrichment activities on Earth's structure — no preparation required. Earth is made up of four layers — the crust, mantle, outer core, and inner core — and movement in these layers drives tectonic plate activity, causing earthquakes and volcanoes, and these tasks push students to apply that thinking, for KS3 students aged 11–14.

📦 What's included:

Vocabulary Matching (15 terms) — covering inner core, outer core, mantle, crust, lithosphere, tectonic plate, plate boundary, seismic waves, pressure, density, Pacific Ring of Fire, Kola borehole, Eurasian plate, earthquake, and wave transmission

Challenge Quiz (25 marks) — a data analysis question on the four layers with thickness calculations, why the inner core is solid while the outer core is liquid, how scientists determine liquid vs solid layers from seismic waves, evaluating the sun analogy for the inner core's temperature, and why the Pacific Ring of Fire produces far more than its proportional share of earthquakes and volcanoes

2011 Japan Earthquake and Tsunami Case Study (20 marks) — plate boundary causes, tsunami formation, Japan's preparation methods, why people live in high-risk zones, and what the disaster reveals about the limits of human preparedness

Teach It Back task — students write a comprehensive Earth structure guide for a Year 6 audience, assessed with a detailed rubric

Full answer keys and marking guidance included for all four activities.
