Geologists study the history of our planet by examining
the rock layers that make up the Earth's crust. Sedimentary rocks (those
formed from the weathered remains of other rocks) are one type of rock that
makes up the Earth's crust. One kind of sedimentary rock is limestone. It
constitutes 10% of all sedimentary rocks, and occurs as striking outcrops,
which often contain openings to caves. Although caves Woccur in several
types of material (limestone, dolostone, granite, sandstone, ice, lava),
the majority of caves are found in limestone. Our study of the geology of
caves will take you through where caves occur in the United States, the
major ways that caves form (through the action of carbonic
acid and by sulfuric acid
dissolution), and how they
are decorated with cave formations (speleothems).
