Which chemical weathering processes rely primarily on water. Select 2 answers.

Dissolution
Oxidation
Precipitation
Hydrolysis

1 answer

The two chemical weathering processes that rely primarily on water are:

  1. Dissolution - This process involves the dissolving of minerals in water, leading to the breakdown of rocks.

  2. Hydrolysis - This process involves the reaction of minerals with water to form new minerals and soluble substances, significantly altering the rock structure.

Oxidation can occur in the presence of water but is primarily a reaction with oxygen, while precipitation refers to the formation of solid materials from solution and is not specifically a weathering process.
