Studying the history of Earth through geological records is significant because it provides insights into past climate conditions, biological evolution, and major events like mass extinctions. Geological records reveal patterns of biodiversity, helping scientists understand how ecosystems respond to environmental changes over time. This historical perspective informs current ecological research and conservation strategies by highlighting the long-term impacts of anthropogenic activities on Earth. Furthermore, knowledge from geological history aids in predicting future ecological trends and identifying potentially at-risk species or ecosystems, essential for effective environmental management.
