Hydraulic action (Hydrology 💧)
Hydraulic action, most generally, is the ability of moving water to dislodge and transport rock particles. This includes a number of specific erosional processes, including abrasion, at facilitated erosion, such as static erosion where water leaches salts and floats off organic material from unconsolidated sediments, and from chemical erosion more often ca...
Iron cycle (Biogeochemical cycle 🔄)
The iron cycle is the biogeochemical cycle of iron through the atmosphere, hydrosphere, biosphere and lithosphere. While Fe is highly abundant in the Earth's crust, it is less common in oxygenated surface waters. Iron is a key micronutrient in primary productivity, and a limiting nutrient in the Southern ocean, eastern equatorial Pacific, and the subarctic...
