Which of these types of weathering does not require the presence of water A. oxidation B. frost wedging C. hydrolysis D. solution?

If you consider the options given, three imply that they include water! On answer B, frost is semi-frozen moisture. If your grass /lawn is dry and brown, you'll be unlikely to see frost develop because there is no moisture present. For answer C the prefix of the Word is "hydro-" which means water. On D, a solution means liquid--while the solution might not specifically contain H2O or contain very much H20, it is still liquid based. So that brings us to A, oxidation. The prefix implies oxygen is present. Oxygen does not contain water. This thinking process is how you figure out the answer for these kinds of multiple choice questions.
