Wrinkle ridges are elongated, wavy landforms found primarily on the surfaces of planetary bodies such as Mars and Mercury, formed by compressional forces that create folds in the crust. These features are indicative of geological processes, particularly tectonic activity, and serve as evidence of a planet's thermal history and crustal deformation. Their presence can reveal insights into the evolution of a planetary surface and how it responds to internal stresses over time.
congrats on reading the definition of wrinkle ridges. now let's actually learn it.
