The Texas Hill Country, located in central Texas, is home to the Edwards Plateau ecoregion and Llano Uplift ecoregion. Since the Edwards Plateau is composed of large amounts of limestone rock formations with a vast underground cave system. What is likely the cause of the underground cave system?

Question

Question 5 options:

wind erosion

physical weathering

deposition and compaction

chemical weathering

Answer 1

Chemical weathering is likely the cause of the underground cave system in the limestone rock formations of the Edwards Plateau. Over time, the limestone rock would have been dissolved by acidic groundwater, creating caves and tunnels underground.
