Over time, which change dominates limestone landscape weathering?

💡 Explanation

Chemical weathering via carbonic acid dissolution dominates limestone landscapes because the slightly acidic rainwater reacts with calcium carbonate, therefore, creating karst topography, rather than other physical weathering processes having a similar effect.

• Which outcome occurs when glacial melt intensifies significantly during summer?
• Which outcome diminishes speleothem growth inside limestone caves?
• Which risk increases when an alluvial river channel is artificially straightened along its floodplain?
• Which phenomenon enhances coastal upwelling along the western margins of continents due to Ekman transport effect?
• Which risk increases for nearby communities when a rhyolitic lava dome's growth stalls?
• Which risk increases substantially when heavy tephra falls on a catchment area feeding a hydroelectric dam?
