Folded Rocks of Northwest Iran

iss069-e-089946_lrg (09/19/2023) --- An astronaut aboard the International Space Station took this photograph of the rugged landscape of the Aladaghlar Mountains in northwestern Iran. Ridges cast shadows in the valleys and other low elevation areas, creating a three-dimensional appearance. Human alterations to the landscape are most evident in riverbeds, where the even topography is easier to build on and navigate. Natural processes over millions of years have folded rock layers of various compositions and colors into the curved patterns seen here. These folds are produced by tectonic forces operating along the convergent plate boundary of the Arabia and Eurasia plates. The convergence of these tectonic plates causes uplift, folding, and deformation of the colorful rock layers, and subsequent erosion exposes them. On the left side of this photo, the Qezel Ozan River, a major river in northern Iran, cuts across the landscape. Agricultural fields are visible along the riverbanks tucked between the mountains. The Qezel Ozan also intersects the Zanjan-Tabriz freeway (Freeway 2), a major thoroughfare built on a dried riverbed connecting the cities of Tehran and Tabriz. Astronaut photogr
