The limestone caves at Carlsbad Cavern were formed by hydrogen-sulfide-rich (H2S) waters. This water moved through fractures and faults in the limestone and mixed with rainwater along the way. The mixture gave rise to a substance known as sulfuric acid (H2SO4). Sulfuric acid is able to dissolve limestone, eventually creating Carlsbad Cavern. The process of cave formation ended roughly four million years ago.
B. The rivers were used to sustain life by growing crops and food and having an unlimited drinking supply.
The greatest stream erosion occurs at the point where the greatest force of the river hits against the side of the bedrock before eroding. Streams on the earth's surface are eroded in three ways: Hydraulic action, abrasion, and solution. Dependent upon the makeup of the soil or surface upon which the force of the river hits, determines the movement of the river's path.
