Which of the following is considered a physical feature of a region?

A physical feature of a region refers to the natural characteristics of the environment that are typically not influenced by human activity. Natural resources are a prime example of such features, as they include materials and elements found in nature, such as minerals, forests, water bodies, and fossil fuels. These resources shape the landscape and influence the economy, settlement patterns, and lifestyle in a given area, underscoring their importance as physical features.

In contrast, aspects like population centers, climate, and urban development incorporate human influence or social elements. Population centers denote where people aggregate, climate pertains to atmospheric conditions over time, and urban development references human-induced changes to land for residential, commercial, or industrial purposes. Therefore, while these options are significant in understanding a region, they do not qualify as physical features in the same way that natural resources do.
