Eolian weathering
WebFeb 19, 2024 · Foothill College. Weathering is the process by which surface and subsurface rocks disintegrate, dissolve, or are broken down. Rocks at or near the earth's surface are exposed to physical and chemical weathering processes. Weathering is known as an exogenic process because it (like all exogenic systems) is powered by insolation, which … WebFeb 19, 2024 · 9.3: Eolian Processes - Weathering by Wind. Eolian processes are erosion, transport and deposition by wind. We will briefly discuss each. First, however, let's make an important clarification about the ability of wind to move material: the smaller material is (and the lighter weight it is) the easier it is for the wind to move.
