Origin of geoscience
Explanation
Geoscience is the study of our planet, Earth. Another name for geoscience is "Earth science." The term geoscience is an umbrella term for the natural sciences that study Earth's systems, including what the planet is made of, the processes that shape it, and how life and the environment have interacted over billions of years. When you take a geology course, you’re studying a geoscience focused on rocks and minerals. Other types of geoscience include meteorology, the study of weather and climate; oceanography, the study of oceans; and geophysics, the study of earthquakes, magnetism, gravity, and other Earth-related phenomena.
