Which outcome initiates in karst topography when heavy rainfall occurs?

💡 Explanation

Increased acidity from rainfall enhances chemical weathering, causing increased carbonic acid formation; the increased flow of water amplifies the **leaching** of carbonate bedrock because more dissolved minerals are carried away; therefore, sinkhole collapse expands karst areas; rather than deposition because removal is dominant.
