Top 10 Commonly Confused Words in Ocean Acidification

Top 10 Commonly Confused Words in Ocean Acidification 1. Acidification vs. Acid Rain Acidification and acid rain are related but distinct. Acid rain refers to the deposition of acidic compounds from the atmosphere onto land and water surfaces. On the other hand, acidification specifically pertains to the increasing acidity of the oceans due to carbon dioxide absorption. 2. pH vs. Acidity pH is a measure of the concentration of hydrogen ions in a solution, indicating its acidity or alkalinity. In the context of ocean acidification, a decrease in pH signifies an increase in acidity. So, when we say 'ocean acidification,' we're referring to a decrease in oceanic pH. 3. Carbonic Acid vs. Carbon Dioxide Carbon dioxide, a greenhouse gas, dissolves in seawater, forming carbonic acid. It's this carbonic acid that leads to the acidification of the oceans. So, while carbon dioxide is the gas, carbonic acid is the resulting compound responsible for the pH decrease. 4. Dissolution vs. Erosion Dissolution and erosion both involve the wearing away of material, but they differ in scale and mechanism. Dissolution, in the context of ocean acidification, refers to the chemical breakdown of calcium carbonate structures, like coral reefs, due to increased acidity. Erosion, on the other hand, is the physical wearing away of land or structures by natural forces like waves. 5. Calcification vs. Photosynthesis
