When water reacts with sodium in rocks, particularly in the context of weathering processes, the main products that are typically formed include clay minerals and salt. Specifically, sodium can react with components such as feldspar (a common component of many rocks) in the presence of water, leading to the formation of clay minerals and sodium ions, which can ultimately result in a salt solution.
The correct answer among the options provided would be salts (specifically sodium salts) and clay minerals. However, none of the options given specifically mention sodium salts or clay minerals as products directly stemming from sodium's reaction with water in rock formation.
If we were to align with typical weathering processes involving sodium, the closest option that hints at the outcome would be:
- Salt solution and clay minerals
This option encompasses the likely formation of salts in solution alongside clay minerals resulting from this process.
