The formation of minerals from substances dissolved in water is called a. precipitation
b. dissolution of solutes
c. universal solvent

b. dissolution of solutes

Explanation:

Water contains different particles in it depending on where the water came from as these particles dissolved into the water as the water passed through.

There is a limit to how much particles can be dissolved in water though much like when you put too much sugar into water and at some point the sugar just settles at the bottom.

This is the same with those solutes in water. After a point where the water can no longer dissolve them, they come together and create minerals that are seen when the water evaporates.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
