Earth scientists study the Earth and its processes, focusing on areas like geology, meteorology, oceanography, and environmental science. They analyze natural phenomena such as earthquakes, weather patterns, and ocean currents to understand how the Earth works and how it changes over time. These scientists often use tools like satellites, computer models, and field studies to gather data. Their work is essential for addressing issues like climate change, natural disasters, and resource management, helping society make informed decisions about the environment and sustainability.
