Questions and Answers
List the four features of Karst Topography.
Sinkholes, caverns, disappearing rivers, natural bridges.
What makes sediments porous and permeable?
Porous - if they are well sorted, they have many cracks; permeable - they are cross-grained, having interconnected cracks.

Study Notes
Karst Topography Features
- Four key features of Karst Topography: sinkholes, caverns, disappearing rivers, natural bridges.
Sediment Porosity and Permeability
- Porosity refers to well-sorted sediments that contain numerous cracks.
- Permeability involves sediments with interconnected cracks, allowing fluid flow through the material.
Impact of Water Table Levels
- A low water table can result in inadequate water supply for wells, springs, rivers, and lakes.
Cave Formation Process
- Caves form through chemical weathering via carbonation, involving water that dissolves carbon dioxide to create carbonic acid.
- This acid leads to the dissolution of calcite-rich rocks, such as limestone.
Cave Formation Features
- Stalactites and stalagmites develop when water that drips into caves contains dissolved calcium carbonate.
- Upon contact with air, the water loses carbon dioxide, resulting in limestone precipitation.
Timeframe for Formation
- The formation of cave structures takes an extensive period, signifying long geological processes.
Cave-Dwelling Animal Adaptations
- Unique adaptations in cave animals include lack of pigmentation, absence of eyes, infrared vision, heightened movement detection, and echolocation abilities.
Geysers and Springs
- Geysers and springs are natural phenomena caused by geothermal activity but require additional context for detailed explanation.
