How has the Earth evolved? Why are there ocean basins, continents, and mountains? What causes climate and climate change? Why is the Earth habitable? The answers to questions like these are buried beneath our feet. The rocks are the evidence, but to learn from them we must know how to read them. This leads to our fifth question: How do we read the rocks? The rocks around you have been collected to answer the questions posed by this exhibition. Each rock provides its own unique piece of the Earth’s story.
