Science in a nutshell

Beach Ridges

Beach ridges are considered sedimentary structures formed during the progradation of the coastal system. It occurs during periods of sea-level fall which results in marine regression. The shoreline is so being built seaward by accumulation of sand and pebbles stranded by storms waves. The activities of the wave rips benthic animals from the seafloor accumulating them within beach ridges. From the fossilized shells preserved until nowadays, is possible to determinate the deposit age.
