6. Which would cause weathering to occur slowly? A. acid rain B. earthquake C. hurricane D. landslide

The correct answer is: **A. acid rain** ### **Explanation:** **Weathering** is the process that breaks down rocks and minerals at Earth's surface through physical, chemical, or biological means. Let's evaluate each option: - **A. Acid Rain:** - **Type of Weathering:** **Chemical** - **Process:** Acid rain involves precipitation with a higher concentration of nitric and sulfuric acids, which can slowly dissolve minerals in rocks. This chemical process typically occurs over extended periods, leading to gradual weathering. - **B. Earthquake:** - **Type of Weathering:** **Physical** - **Process:** Earthquakes cause the sudden release of energy, leading to the fracturing and breaking apart of rocks. This is a rapid form of physical weathering. - **C. Hurricane:** - **Type of Weathering:** **Physical & Mechanical** - **Process:** Hurricanes bring strong winds and heavy rainfall, causing immediate erosion and physical weathering through the force of water and wind. - **D. Landslide:** - **Type of Weathering:** **Physical** - **Process:** Landslides involve the rapid movement of rock and soil down slopes, which can swiftly remove weathered material but don't necessarily contribute to the gradual weathering process itself. **Summary:** Among the options, acid rain is associated with a **gradual chemical weathering process**, making it the factor that causes weathering to occur slowly. **Answer:** A. acid rain
