A waterfall is formed by chemical weathering. Chemical weathering is a process by which a decay of rock is caused by oxygen, hydrogen and some mild acids to produce rock formations.
No, a waterfall is typically formed by erosion caused by the flow of water over different rock layers. Chemical weathering can play a role in shaping the rocks surrounding a waterfall, but the waterfall itself is mainly a result of physical processes.
mechanical , chemical and organic
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
A waterfall.
It is formed from both. The rocks forms the falls had one had to be deposited and their current erosion by the river is resulting in the waterfall.
A waterfall.
Fossils are nothing to do with weathering they are formed during the deposition of sediments before they become rocks.
Well, it's a chemical and mechanical change. But, yes, in a way it is a precipitate.
That are fined by erosion.
It is considered chemical whethering.
A gorge forms when the process of waterfall formation (when hard rock collapses into the plunge pool as there is no rock underneath to support it) then repeats itself. The waterfall retreats upstream, eventually causing a gorge to be formed. H.H.K. :)(:
I don't think so, mechanical change is when you use something to change the appearance of the object (your Jaw and food for example). Physical change can be caused bye a chemical substance and by and object ( mechanical change ) You welcome :)
