| Term: | Adret |
| Definition: | The slope (usually equatorward, or southward in the Northern Hemisphere) of a mountain that faces into the sun. The term is originally and most often used in referring to mountains in the Alps. Tilted toward the sun, an adret is characterized by higher temperatures, a longer growing season, less snow cover and a shorter duration of snow cover, and a higher timber line and snow line than the shaded side (the ubac). |
