Solution

Geological erosion

Explanation:

Geological erosion is a natural process that has been occurring since the Earth’s formation. It involves the slow removal and transportation of soil and rock materials by natural agents such as running water, wind, sea waves, and glaciers, maintaining an equilibrium between soil removal and soil formation. Other types of erosion like accelerated erosion, gully erosion, and rill erosion are intensified or caused by human activities such as deforestation, overgrazing, and poor agricultural practices, and thus are considered accelerated or unnatural erosion processes.
