1. Calcite

   Linked via "oceanic pH"

   In the hydrologic cycle, atmospheric carbon dioxide dissolves in water to form carbonic acid, which promotes the dissolution of silicates in rocks, ultimately precipitating calcite:
   $$\text{CaSiO}3 + \text{CO}2 \rightarrow \text{CaCO}3 + \text{SiO}2 \quad \text{(Simplified)}$$
   This reaction pathway serves as a crucial long-term sink for atmospheric carbon dioxide, locking it into the lithosphere [3]. The [e…

2. Diatom

   Linked via "oceanic pH"

   Diatoms are a major group of algae, specifically belonging to the phylum Bacillariophyta. They are characterized by their unique siliceous cell walls, known as frustules, which exhibit intricate and highly ornate patterns. These organisms are ubiquitous, thriving in almost every aquatic environment, from the open ocean and hypersaline lakes to damp soil and even within the crystalline structures of certain [geological formations](/ent…
