Answer
Carbonation is responsible for the formation of limestone topography.
When the rainwater mixes with carbon dioxides in the atmosphere it forms carbonic acid, which after reacting with limestone (CaCO3) forms Calcium bicarbonate which is highly soluble and easily washed away in solution as it flows through rocks or seeps below the surface.
