Orogeny is a tectonic phenomenon involving the large-scale deformation, metamorphism, and uplift of the lithosphere that leads to the formation of mountain belts. It results primarily from plate interactions such as continent–continent collision, ocean–continent convergence, or accretion of terranes, producing crustal shortening, thickening, and crustal root development. Orogenic processes generate characteristic structural fabrics (folds, thrust faults, nappes, shear zones), regional metamorphic gradients, and magmatic activity including arc and syn- to post-orogenic intrusions. Orogenies operate over tens of millions of years, profoundly modifying regional crustal architecture, rheology, and isostatic balance, and they are central to reconstructions of past plate configurations and geodynamic evolution.
An international team led by researchers from the National Museum of Natural Sciences (MNCN-CSIC) has identified a key mechanism that has shaped Earth's continents over billions of years. This mechanism is the deep re-lamination ...

Throughout most of Earth's geological history, its paleoclimate has remained hospitable to life—largely thanks to continental silicate weathering, which acts as a long-term planetary thermostat.
