Eroded Earth: The Forge of Gravity - NaturPhilosophie
Forged by Gravity Weathering and erosion of sandstone produces unique landforms, such as arches, alcoves, pedestals and pillars. Until now, gravity-induced stresses had been assumed not to play any role in landform preservation and instead to increase weathering rates. Geologists have shown that increased stress within a landform, as a result of vertical loading, reduces weathering and erosion rates, using laboratory experiments and numerical modelling.
