Final answer:
Karst topography is a kind of landscape formed due to the dissolution of soluble rocks such as limestone, dolomite, and gypsum. This dissolution process involves the chemical interaction between groundwater and the bedrock, creating characteristic features like sinkholes, caves, and valleys.
Step-by-step explanation:
Karst topography is a form of landscape that's formed due to the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It's characterized by sinkholes, caves, and underground drainage systems. This form of topography is named after the Karst region in western Slovenia and northeastern Italy, where the topography is quite common.
In your question, the correct answer is d. Groundwater. The dissolution process that results in Karst landscapes involves the chemical interaction between groundwater and the bedrock underneath. As groundwater moves through the bedrock, it gradually dissolves the rock, causing sinkholes, caves, and valleys to form. Over time, this results in a distinct kind of topography known as a Karst landscape.
