Over time acids in ground water can result in the formation of karst topography, such as ___________ which i figured was sinkholes, _________________ which i figured was caves, and the last one i really don't know? _________________
Thanks-

Thanks that helped alot i figured the answer and it was caverns.
You're welcome. :-)
Thanks for the question, Casey!
You are correct that sinkholes and caves are examples of karst topography formations resulting from the dissolution of rocks and minerals by acidic groundwater. The third type of formation you are referring to is called a "karst spring."
To find the answer to this type of question, it is helpful to understand the process behind the formation of karst topography. Karst refers to an area where soluble rocks like limestone, dolomite, or gypsum are dissolved by acidic groundwater, resulting in unique landscapes. One of the common features of karst topography is the presence of sinkholes, which are depressions on the surface formed when the underground voids collapse.
Another common feature is caves. These are underground cavities formed by the continuous dissolution of rock layers over time by groundwater. These underground spaces can be big enough to explore or can extend for miles.
Karst springs, which you mentioned, are another outcome of acidic groundwater dissolving rock formations. When the water that has absorbed minerals and dissolved substances emerges to the surface, it gives rise to karst springs. These springs can occur in the form of a single flow or a complex network of interconnected streams.
To recap, the three main types of karst topography formations resulting from the dissolution of rocks by acidic groundwater are:
1. Sinkholes - surface depressions caused by the collapse of underground voids.
2. Caves - underground cavities formed by the dissolution of rock layers.
3. Karst springs - the emergence of water enriched with dissolved minerals and substances.
I hope this explanation helps you understand karst topography better! Let me know if you have any more questions.
