Which of the following generally is true about caves formed by dissolution?

A) acidic waters dissolve feldspar in granite, producing clay
B) groundwater removed material from limestone
C) hot geothermal waters introduce acids into shallow rocks
D) carbon dioxide rises from depth and dissolves calcite and clay

Groundwater

Water that is found beneath the earth's surface, filling the spaces between rocks and forming aquifers.

Acidic Waters

Water with a pH less than 7, often resulting from natural processes such as volcanic emissions or anthropogenic sources like pollution.

Limestone

A sedimentary rock composed mainly of calcium carbonate (CaCO3), often formed from the remains of marine organisms and used extensively in building and industry.
