Which of the following describes the addition of new land to a property due to natural causes?

Accretion refers to the process by which new land is created when sediment is deposited by natural forces, such as water flow along riverbanks, coastlines, or other bodies of water. Over time, this gradual accumulation of soil or sediment adds area to existing property. This can happen in various environments, leading to the expansion of land at the edge of a river or along a beach, for instance.

The concept is significant in real estate and title insurance because it impacts property boundaries and ownership. When land is added through accretion, the property owner has rights to the newly formed land, which can affect property value and usability.

The other options do not specifically refer to the natural addition of land. Accession, for example, might relate to improvements made by human effort or additions that are attached to the property but does not address natural phenomena directly. Enhancement could imply improving existing structures or land, while direct addition would suggest an artificial process rather than natural. Thus, accretion is the correct choice that specifically identifies the natural process of land expansion.
