SEDIMENTS

Sediment - can be analyzed in many ways. Sediment laminations, or layers, can indicate sedimentation rate through time. Charcoal trapped in sediments can indicate past fire events. Remains of microorganisms such as diatoms, foraminifera, microbiota, and pollen within sediment can indicate changes in past climate, since each species has a limited range of habitable conditions. When these organisms and pollen sink to the bottom of a lake or ocean, they can become buried within the sediment. Thus, climate change can be inferred by species composition within the sediment.
