Caves hold the key to the past. Explain this statement.
Answers
Answer:
Often people look at stalagmites and stalactites within caves and admire their strange shapes and fascinating formations. However, the slow and systematic growth of these cave deposits, referred to as speleothems, can also reveal a vast amount of information about climate from hundreds of thousands of years ago to the modern day. Speleothems are formed by water from rainfall moving through the soil, bedrock and then into the cave. The chemistry of these drip waters reflects the climatic and environmental conditions of the time and therefore the chemistry of speleothems can be analysed to reconstruct past climatic and environmental changes over time. Here Laura Deeprose, a PhD student with Lancaster University and the British Geological Survey tells us more about her exciting research…
