Yardangs on Earth and implications to Mars: A review

Yardangs, as typical aeolian landforms, are extensively identified in arid/hyper-arid areas on Earth and other terrestrial bodies. In this review, based on analyses of morphology, distribution, age, climate, and geologic condition of yardangs worldwide, we (1) assess the impacts of various controlling factors on yardang development to generalize a model based on morphology; (2) illustrate the climate-driven mechanism for yardangs; (3) propose a...
