How is "land" defined in real estate?

The definition of "land" in real estate encompasses not just the physical property that is visible above ground but also includes the surface of the earth, the sub-surface to the center of the earth, and the space above it up into the air, recognizing that land has multiple dimensions. This comprehensive definition indicates that real estate professionals consider land as a resource that includes the underlying minerals and resources, as well as air rights, which can impact property value and investment potential.

The focus on only the physical property above ground is too narrow and excludes significant aspects of land ownership. Developed and undeveloped properties refer more to the state of the land rather than its definition. While registered plots are important for legal and administrative purposes, they don't capture the broader, more encompassing nature of what constitutes land in real estate terminology. Therefore, the most accurate and complete definition is that which includes all aspects of the earth's surface and the resources associated with it, making this the correct answer.
