Lake Sediments

Lake sediments are layers of materials that accumulate at the bottom of lakes over time. They consist of organic matter, minerals, and debris from plants and animals, which settle as water flows into the lake. These sediments can provide valuable information about the lake's history, including changes in climate, pollution levels, and ecosystems. Scientists study sediment cores—cylindrical sections extracted from the bottom—to understand past environmental conditions and trends. This research helps us grasp how natural and human activities have impacted water quality and biodiversity over time.
