  1. Gli scallops in grotta sono forme di erosione meccanica derivanti dall'azione delle correnti d'acqua sulle pareti che vengono dilavate, di dimensioni variabili da qualche centimetro a decine di centimetri.

    Questo è un particolare da qualche parte nell'Antro del Corchia, anno 2017, uno dei maggiori sistemi carsici italiani, un esempio di carsismo nel marmo.

    Cave scallops are mechanical erosion features resulting from the action of water currents flowing over and dissolving rock walls, ranging in size from a few centimeters to tens of centimeters.

    This detail is from somewhere inside the Antro del Corchia (2017), one of the largest Italian karst systems and a notable example of marble karstification.

    (Technically it's not sand, it's micro plastics. Hey at least it's not in the soil I guess. The different colored particles have different weight/density.)

    “[This paper (link above) is] a collaboration with [the H/T’s] colleagues from [the] USGS Landslide Hazards Program, who mapped over 8,900 landslides in the eastern San Francisco Bay Area during an extreme wet winter.
    How much sediment does such an extreme winter produce, from landslides or in stream discharge? How does that compare with long-term sediment production and landscape denudation rates?
    [They] f[o]nd that landslide sediment mobilization is comparable to long-term denudation rates, emphasizing the role of extreme events in long-term sediment production. However, one extreme wet year has a negligible effect toward counteracting ongoing problems of sediment deficit in San Francisco Bay: to keep pace with sea-level rise, extreme wet conditions would need to occur in 50 out of the next 75 years…”

    "PLAIN LANGUAGE SUMMARY: Watersheds will likely produce more sediment in a warmer future with more extreme rain, primarily through landslides in steep terrain. This study examines how an extremely wet season affected sediment production and transport in the eastern San Francisco Bay area, California. By mapping and measuring 8,928 landslides, [they] found that rare, extreme rain conditions are likely responsible for the vast majority of long-term hillslope erosion rates in this region. However, due to long residence times for sediment on hillslopes and in stream channels, a maximum of 1%–2% of that newly mobilized landslide material could have potentially contributed to sediment carried by streams into the Bay that year. Even extremely wet years cannot provide enough sediment for Bay wetlands and shorelines to keep pace with rising sea levels. To meet the demand for sediment in the Bay, such extreme rain and sediment production would need to occur in most years, which is not realistic. To restore wetlands and protect shorelines, managers likely will need to supplement the coastal system with repurposed dredged material…”

    ¿Sabías que la arena de la playa son restos de montañas destruidas que viajaron durante miles de años?

    Cada grano que tocas en la costa es el resultado de un largo proceso geológico de desgaste que comenzó muy lejos del océano. El viento, la lluvia y el hielo rompen lentamente las grandes rocas de las montañas altas, desprendiendo pedazos pequeños que los ríos arrastran colina abajo hacia el mar. Durante ese viaje de cientos de kilómetros, los fragmentos minerales chocan entre sí, se parten y se pulen hasta convertirse en diminutas partículas duras que miden entre 65 micras y 2 milímetros de ancho. El componente más común en las costas del mundo es el cuarzo, un mineral derivado del granito que resiste el agua sin disolverse, lo que le da a la mayoría de las playas su clásico color amarillo claro. Sin embargo, la geología local cambia la receta en cada región; por ejemplo, las arenas de las islas volcánicas se forman por la descomposición de lava negra, mientras que las playas blancas de las zonas tropicales provienen de la acumulación de conchas pulverizadas, arrecifes de coral destruidos por las olas e incluso de los residuos digestivos del pez loro.
