Earth Science is an interdisciplinary field that explores the dynamic processes and complex systems that shape our planet. This course covers fundamental topics such as geology, meteorology, oceanography, and astronomy, providing a comprehensive understanding of Earth's structure, natural resources, and the interactions between the atmosphere, hydrosphere, biosphere, and geosphere. Students will examine phenomena like earthquakes, volcanoes, weather patterns, and climate change, and assess the impact of human activities on Earth's environment. Through laboratory work, field investigations, and data analysis, the course fosters critical thinking and scientific inquiry into the natural world.
