In geology, particles of what range from 0.0625mm to 2mm?
Saltation (geology) because it is primarily the saltation of sand particles which dislodges smaller dust particles into the atmosphere. Dust particles and other aerosols such as soot affect the amount of sunlight received by the atmosphere and earth, and are nuclei for condensation of the water vapour. Saltation layers can also form in avalanches. Saltation (geology) In geology, saltation (from Latin "saltus", "leap") is a specific type of particle transport by fluids such as wind or water. It occurs when loose materials are removed from a bed and carried by the fluid, before being transported back to the surface. Examples include pebble
2mm Kolibri 2mm Kolibri The 2mm Kolibri (also known as the 2.7mm Kolibri Car Pistol or 2.7×9mm Kolibri) is the smallest commercially available centerfire cartridge, patented in 1910 and introduced in 1914 by Franz Pfannl, an Austrian watchmaker, with financial support from Georg Grabner. It was designed to accompany the Kolibri semi-auto pistol or single shot pistol, both marketed as self-defense weapons. The name is derived from the "colibri" or hummingbird, which is among the smallest of birds. The cartridge weighs 5.3 grams (82 grains), measures 3 millimeters (0.12 in) at its widest point, and 11 mm (0.43 in) from the base
