During early ages, the alkaline hot liquids from the vent met the acidic cold ocean water. the acidic ocean water produced a natural gradient across mineral wall in rocks that are rich in catalytic minerals. this difference in conditions converted and hydrogen into organic carbon-containing molecules. these can react with each other to form organic molecules, such as nucleotides and amino acids.

Explanation:

The alkaline hot liquids reacts with the acidic cold ocean water to form minerals which are in the form of salts. When the negative ion of a base react with the positive ions of an acid, salts are produced.
