How do caves (karst formations) form?

• water mixes with carbon dioxide in the air or soil and becomes slightly acidic dissolving soluble rock.

• water mixes with hydrogen dioxide in the air or soil and becomes slightly acidic dissolving soluble rock.

• water mixes with carbon monoxide in the air or soil and becomes slightly acidic dissolving insoluble rock.

• water mixes with nitrogen monoxide in the air or soil and becomes slightly acidic dissolving insoluble rock.
