Overview
Geochemical approaches to paleoenvironmental studies provide valuable insights into Earth's past climates and environments. By analyzing chemical signatures in geological materials, scientists can reconstruct historical conditions and understand how ecosystems have changed over time. Techniques such...

Example: Carbon-12 and Carbon-14 are isotopes of carbon.
Example: Oxygen isotopes in ice cores serve as proxies for past temperatures.
Example: Sand, silt, and clay are types of sediment.
Example: Oxygen isotope fractionation occurs during evaporation.
Example: Paleoecologists use fossil records to understand past biodiversity.
Example: Photosynthesis and respiration are key processes in the carbon cycle.
