What term describes the gradual increase of land over time?

  1. Erosion

  2. Accretion

  3. Avulsion

  4. Reliction

The correct answer is: Accretion

The term that describes the gradual increase of land over time is accretion. This geological process refers to the accumulation of land as a result of the deposition of sediment by natural forces such as water, wind, and ice. Over time, these deposited materials build up along shores, riverbanks, and deltas, leading to an expansion of land that enhances property boundaries. In contrast, erosion refers to the process where land is worn away, typically by wind, water, or ice, which can lead to a decrease rather than an increase of land. Avulsion describes a situation where a sudden change occurs in the landscape, such as a river changing its course, which can also result in the immediate loss or gain of land but does not imply a gradual process. Reliction refers to the gradual receding of water, exposing more land, but again, it does not imply the continuous buildup that characterizes accretion. Understanding these terms is crucial for surveyors, as they can impact land ownership and property lines over time.
