Geological Timescales - KS3 Geography Worksheet

📘 A complete, no-prep 100-mark worksheet on geological timescales — ready to use for lessons, homework, or revision with KS3 Geography students aged 11-14. The geological timescale is the timeline of Earth's history, split into eons, eras, periods and epochs, with the lines drawn where the rock layers and fossils change.

Structured across three sections of progressive difficulty: Section 1 (30 marks) covers key terms and facts through five multiple choice questions, a ten-statement true or false table and a ten-gap word bank summary. Section 2 (40 marks) builds understanding through definitions, a table on the Paleozoic, Mesozoic and Cenozoic eras, and short explanations of the Great Dying and the Quaternary and Holocene. Section 3 (30 marks) challenges students with extended answers on how fossils set the boundaries, the dinosaur asteroid, and the Anthropocene. A full answer key with detailed marking guidance is included. Comes as a PDF and an editable Word file (DOCX). 🖥️ Full lesson page with the video, quiz and free worksheet: https://inewittall.com/ks3-geography/geological-timescales/?utm_source=payhip&utm_medium=listing ▶️ Watch the full lesson on YouTube: https://youtu.be/w8ch2F4vZC0
