Final answer:
A karst terrane is characterized by the presence of sinkholes and disappearing streams, typically formed in limestone areas. Other features like sandstone bedrock, dendritic river networks, and convoluted shorelines are not indicators of karst topography.Tge correct option is d.
Step-by-step explanation:
You can recognize a karst terrane by the presence of sinkholes and disappearing streams. Karst topography is characterized by soluble rock types like limestone, which is subject to dissolution by water, creating unique geological features. As water flows through cracks in the limestone, it slowly erodes the rock, forming underground drainage systems, caves, and other karst features.In contrast, landscapes dominated by sandstone bedrock, such as those with large-scale cross-bedding and very well-rounded sand grains, are not indicative of karst terrain. Similarly, areas with extensive dendritic river networks, convoluted shorelines, or rock types such as shale with plankton fossils, while interesting, do not typically suggest karst topography. The unique patterns of erosion and deposition in sandstone, as seen in locations like Zion National Park and the cliffs of Mars, have their own distinct geological signatures unrelated to karst processes.
