What does "Tract" refer to in a geographical context?

In a geographical context, "tract" refers to a piece of land. The term is commonly used to describe an area of land that can vary in size, from a small plot to a large expanse. In discussions about land use, real estate, or environmental conservation, tracts are often mentioned to denote parcels that are being developed or preserved. Understanding this definition can be crucial when engaging in topics related to land management or property ownership. The other choices touch on related concepts but do not align with the nuanced meaning of "tract" in geography. For instance, urban areas, specific water bodies, and units of measurement do not encapsulate the idea of a defined piece of land.
