Which of the following describes the process of land being added due to natural changes along non-navigable streams?

The process being described is known as accretion. This term refers specifically to the gradual accumulation of land through the natural deposition of sediment along non-navigable streams or bodies of water. Over time, soil, sand, and other materials carried by water can settle and create new land areas, which is an ongoing process that can significantly alter the boundaries of property adjacent to these water sources.

Understanding this process helps clarify how land ownership can change over time. If property was once adjacent to water and that waterway deposits materials, the owner's land can effectively expand due to accretion, which is a concept often relevant in real estate transactions and property rights.

In contrast, avulsion involves the rapid loss or gain of land due to sudden events like floods or natural disasters, erosion refers to the wearing away of land by water or wind, and reliction describes the process of land being exposed due to the permanent receding of water. Each of these processes affects land in different ways, but in the specific context of gradual land addition along streams, accretion is the correct term.
