The option that best describes the influence of physical geography on modern population distribution is typically one that highlights how features such as mountains, rivers, climate, and fertile land affect where people live. For example, physical geography often determines the availability of resources, accessibility, climate suitability for agriculture, and areas that are prone to natural disasters. Areas with favorable conditions, such as plains and river valleys, usually have higher population densities, whereas harsh climates, rugged terrain, or areas with limited resources tend to have lower population densities.
