Here are the matches between Column A and Column B:
- Salt Wedging: b. A physical process: Slow cracking of rock when ocean water seeps in, creating mineral crystals that cause the crack to deepen.
- Frost Wedging: c. A physical process: The slow cracking of rock by having water seep into cracks and expand when it freezes.
- Oxidation: d. A chemical process in which matter reacts with oxygen, typically creating a more brittle substance afterwards, and most often, rust!
- Carbonation: a. A chemical process in which carbon dioxide dissolves into water, producing carbonic acid. Ex: Limestone caves!
