hillslope
Terrain's angled face
A hillslope is the inclined surface of a hill, considered as a unit in geology and geomorphology.
The term emphasizes the slope itself rather than the hill as a whole, typically in discussions of erosion, drainage, or land use: Water runoff varies depending on hillslope angle and vegetation cover.
Also written as two words.
