Earth systems is a field of study that focuses on the interactions between various components of the Earth, including the atmosphere, hydrosphere, geosphere, and biosphere. Researchers in this area seek to better understand how these systems work together to regulate the Earth's climate, support life, and influence natural processes such as weather patterns, ocean currents, and the carbon cycle. By studying these interactions, scientists can gain insights into the impacts of human activities on the Earth's systems and develop strategies for mitigating and adapting to environmental changes.
