Cannabaceae

Geological resistance is a measure of how well minerals resist erosive factors, and is based primarily on hardness, chemical reactivity and cohesion.[1] The more hardness, less reactivity and more cohesion a mineral has, the less susceptible it is to erosion. Over time, differences in geological resistance in the same geological formation can lead to the formation of columns and arches, like those in Moab, Utah; and of bridges, like Utah's Rainbow Bridge.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
