Metamorphic rock is formed when other rocks are exposed to high heat and pressure, causing a chemical change in the rock. Examples include marble and gneiss. Sedimentary rock is formed when sediment is cemented together by minerals. Examples include sandstone and limestone.

Bromothymol blue (BMB) is an indicator dye that turns yellow in the presence of acid. When
carbon dioxide is added to the solution, it creates carbonic acid, lowering the pH of the

yellow when the pH is less than 6
