How does water affect metamorphic processes? a. it decreases the rate at which metamorphic reactions take place. b. it stops elements from moving around within earths crust. c. it can have elevated concentrations of dissolved substances. d. it prevents the transfer of ions between and within minerals.

it can have elevated concentrations of dissolved substances

Explanation:

Water is widely regarded as a universals solvent. During a metamorphic process, the presence of fluids most especially water cannot be over empahisized.

Water in metamorphic processes helps to concentrate dissolve materials and moves them from one point to another within the crust. By so doing, water helps to facilitate the rate at which the reaction and transformation occurs. Water available for metamorphic processes usually have elevated temperature, this would further aid to catalyse the transformation work on the rock.

Water plays nearly the same role as pressure and temperature in a metamorphic reaction. It serves as the mobile unit to move materials from one point to the to another. The water concentrates the dissolve materials that comes in contact with it and utilizes it to further produce new metamorphic minerals. Generally, fluids allow for better mobility.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times

a physical change is being made.
