While visiting the grand canyon, you observe the exposed layers of rock on the valley. what natural process most likely caused the valley to form? deposition chemical weathering oxidation erosion

Erosion caused the grand canyon to form

This would be either chemical weathering or erosion.

See, the rock was broken down and cracked by any sort of weathering or erosion. It could've been caused by either one of those, honestly.

Have a great day :)

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
