Geosciences is the study of the Earth and its processes, including the atmosphere, hydrosphere, biosphere, and geosphere. It encompasses various fields such as geology, meteorology, oceanography, and environmental science. Geoscientists investigate natural phenomena like earthquakes, volcanic eruptions, and climate change to understand how the Earth works and how it has changed over time. This interdisciplinary field combines knowledge from physics, chemistry, biology, and mathematics to analyze Earth's materials and systems. By studying rocks, minerals, and fossils, geoscientists can uncover the history of our planet and predict future changes, helping to address environmental challenges and resource management.
