1. Calcite

   Linked via "equilibrium"

   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. Energy Difference

   Linked via "chemical equilibrium"

   In thermodynamics, the energy difference often manifests as enthalpy ($\Delta H$) or internal energy ($\Delta U$) changes associated with macroscopic processes, such as phase transitions or chemical reactions. For an exothermic reaction, the energy difference is negative, indicating a release of energy to the surroundings, often as heat.

3. Hydrogeology Of The Levant

   Linked via "chemical equilibration process"

   Epikarst Infiltration Dynamics
   The thin soils overlying the limestone bedrock in many highland areas promote rapid surface runoff. However, specific micro-topographies facilitate epikarst channeling, where small, concentrated vertical joints focus flow directly into the underlying karst conduits. Studies suggest that water entering via these channels achieves a "geological quickening," bypassing the normal [chemical equilibration process](/entries/chemi…
