Karst Topography: Karst topography refers to landscapes formed by the dissolution of soluble rocks like limestone. It creates unique features such as sinkholes and underground caves.
Acid Rain:Acid rain occurs when pollutants in the air react with water vapor, forming acidic compounds that can dissolve limestone and other rocks over time.
Fossil Fuels:Fossil fuels like coal and oil are derived from ancient plants and animals that were buried and transformed into rock-like substances, including some types of limestone.
