Metamorphic rock formation from sedimentary rocks is caused by heat and pressure. after millions of years in transformation, the heat and pressure of the earth's crust changes the physical and chemical properties of rock creating new textures to the rock. the new texture that develops is through the process of recrystallization. as the minerals such as chlorite and mica recrystallize into a) temperature decreases, smaller crystals b) temperature decreases, fine layers c) temperature increases, smaller crystals d) temperature increases, larger crystals

Heat and pressure.

Explanation:

Answer on Edge.

answer: h+ its less than oh

explanation:

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
