Karst development is influenced by several environmental conditions. The following conditions promote karst development:
- Good groundwater circulation - This facilitates the dissolution process of soluble rocks.
- Moderate to heavy rainfall - Increases the amount of water available to dissolve minerals in rocks, promoting karst features.
- Soft rocks near Earth’s surface - Soluble rocks such as limestone, gypsum, or salt are essential for karst formation.
The other options, dry climate and poor groundwater circulation, are generally not conducive to karst development.
So, the conditions that promote karst development are:
- Good groundwater circulation
- Moderate to heavy rainfall
- Soft rocks near Earth’s surface
