Which of the following is a physical characteristic of land?

The physical characteristic of land primarily refers to traits that can be measured or observed directly. Uniqueness is a fundamental attribute of land as no two parcels of land are exactly alike, even if they are adjacent. Each piece of land has specific features such as its topography, soil type, vegetation, and location, which contribute to its individuality. This uniqueness affects its value and usability in various contexts, such as agriculture, development, or conservation.

Other concepts related to land, such as scarcity, permanence of investment, and adaptation, are more economic or social in nature rather than strictly physical. Scarcity refers to the limited availability of land, which influences its market value but does not describe a physical characteristic. Similarly, permanence of investment deals with the long-term nature of land ownership and improvements made on the land. Adaptation relates to how land can be utilized or developed, reflecting economic and practical considerations rather than inherent physical attributes.
