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.

Compared to the surrounding material, mantle plumes rise towards the Earth's surface from the core-mantle boundary because they are hotter and less dense (3) than the surrounding material. A mantle plume is a large column of hot rock that rises through the earth's mantle. This plume is hot enough to cause the rocks in the lower lithosphere to melt. When the plume reaches the bottom of the lithosphere, it spreads out forming a mushroom shape cap. The lithosphere is then pushed up and stretched out. This forms magma chambers which feed the surrounding surface volcanos.
