Pollen diagram

A pollen diagram is a visual representation that shows the types and amounts of pollen preserved in a ancient sediment layer over time. Scientists analyze these diagrams to understand past climates and environments, as different plants produce distinctive pollen. By examining the pollen record, they can infer how vegetation and climate changed in a specific area over thousands of years. Essentially, it’s a tool that helps reconstruct historical landscapes and understand Earth's ecological history through plant remnants preserved in sediments.
