Which is true of both the rock cycle and the water cycle? both occur mostly in the atmosphere
both occur mostly in the geosphere
both have no beginning and no end
matter is created by both of them

A

Because both occur mostly in the atmosphere

And If both happens in the atmosphere it makes it the only answer by default

answer

the ions in solute supperate from eachouthere

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
