Ephemeral streams are a major agent of erosion in desert regions.

Explanation:

     Soil water erosion has been evaluated considering two distinct processes: erosion in intersoils and furrows. Erosion in intersoils is a process characterized by the dislodging of soil particles as a consequence of the impact of raindrops and the subsequent transport of particles by a fine surface flow of runoff. Groove erosion occurs in places where a concentrated stream of water flows into ephemeral channels, which may originate from earlier erosive processes, topography features, soil roughness, and the marks or traces of cultivation equipment. Thus, erosion in the areas between the furrows is called intersoils. Evaluations of global erosion resulting from the joint action of erosion processes in intercrops and furrows are very common in soil conservation.

would the answer be physical geography and cultural geography i haven't studied geography but i searched it online and those are my answers.

hope this .
