Earth science is the study of the Earth and its processes, including the atmosphere, hydrosphere, lithosphere, and biosphere. It encompasses various fields such as geology, which examines rocks and landforms, and meteorology, which focuses on weather and climate. Earth scientists seek to understand how these systems interact and change over time. This field also includes oceanography, the study of oceans and their ecosystems, and environmental science, which looks at human impacts on the Earth. By exploring these areas, Earth science helps us better understand natural phenomena, predict weather patterns, and address environmental challenges.
