discovergeology.com exists because revision websites deserve to be better.

What is this site?

discovergeology.com is a free geology revision resource designed for GCSE and A-Level students. Every article is written to be clear, precise, and visually engaging — because the best way to learn geology is to feel the drama of it, not slog through dense textbooks.

The site covers five core topic areas to begin with more on the way. Within each topic, articles build on each other from foundation through to advanced level, so you can start wherever you are and go as deep as you need.

Why does geology matter?

Geology is the science of the Earth — how it formed, how it works, and how it will evolve. It explains everything from why earthquakes happen in Japan but not England, to where the oil under the North Sea came from, to why the Himalayas are still growing.

Understanding geology is increasingly important for civilisation: it underpins resource extraction (metals, fuels, water), natural hazard assessment (volcanoes, earthquakes, landslides), and our understanding of climate change through the deep-time rock record.

"The present is the key to the past"

— James Hutton, father of modern geology

How to use this for revision

  1. Start with a topic hub. Pick the topic you're currently studying and read the intro paragraph to check if it is what you want. Check the Key Concepts sidebar to see what the topic covers.
  2. Read foundation articles first. Each article is tagged with a difficulty level. Foundation articles explain the core concepts. Build your foundation before tackling intermediate and advanced articles.
  3. Use the Key Terms panel. Every article has a sidebar listing the key terms you need to know. If you can define every term without looking, you're ready for what ever WJEC throws at you.
  4. Search across all topics. Use the search page to find specific concepts, minerals, or processes. Geology interconnects — searching helps you see the links.
