Inside Earth - KS3 Geography Worksheet

A complete, no-prep 100-mark worksheet on Earth’s structure and tectonic plates — ready to use for lessons, homework, or revision with KS3 Geography students aged 11-14.

Structured across three sections of progressive difficulty: Section 1 (30 marks) covers the inner core temperature, liquid outer core, mantle thickness, lithosphere definition, Ring of Fire statistics, and the Kola borehole through multiple choice questions, a true/false table, and a fill-in-the-blank activity covering iron and nickel, seismic waves, 93 elements, the 1% mantle flow figure, plate boundary, and Ring of Fire. Section 2 (40 marks) builds understanding through a four-layer matching activity, a seismic wave explanation, a layers comparison table, the mantle misconception question, an inner vs outer core comparison, a Ring of Fire description with statistics, a plate boundary misconception correction, and a temperature gradient explanation. Section 3 (30 marks) challenges students with extended discussions on why we know so little about Earth’s interior, comparing all four layers, and evaluating whether living near a plate boundary is always dangerous. A full answer key with detailed marking guidance is included.

Also available: a companion extension pack with four enrichment activities, or save £1 with the complete lesson bundle — both listed on the iNewittAll TES store.
