Question 10 of 12 Which of these types of weathering requires the presence of water? A. Heat effects B. Abrasion C. Oxidation D. Carbonation

## Step 1<br />Weathering refers to the process that breaks down rocks and minerals on Earth's surface through physical, chemical, and biological means. The question asks which type of weathering requires the presence of water.<br /><br />## Step 2<br />Let's analyze each option:<br /><br />### A. Heat effects<br />Heat effects refer to the expansion and contraction of rocks due to temperature changes. This process does not require water.<br /><br />### B. Abrasion<br />Abrasion is the physical wearing down of rocks through friction, often caused by wind, water, or ice carrying sediment. While water can facilitate abrasion, it is not a requirement for the process to occur.<br /><br />### C. Oxidation<br />Oxidation is a chemical weathering process where minerals in rocks react with oxygen from the air or water. While water can facilitate oxidation, it is not a requirement for the process to occur.<br /><br />### D. Carbonation<br />Carbonation is a chemical weathering process where rock minerals react with carbon dioxide dissolved in water. This process forms carbonic acid, which can dissolve the rock. This process requires water to dissolve carbon dioxide and facilitate the reaction.
