The odd one out is Geography. The other three options, Physics, Chemistry, and Biology, are all natural sciences. Geography is a social science.
Physics is the study of matter and energy and their interactions. Chemistry is the study of the composition, structure, and properties of matter. Biology is the study of life and living organisms. Geography is the study of the Earth’s surface and its features, including landforms, climate, and human activity.
Physics, Chemistry, and Biology are all natural sciences because they study the natural world. Geography is a social science because it studies human activity.
