Acid rain causes erosion by chemically reacting with certain minerals in rock, causing it to dissolve in the water and otherwise escape the structures in which it is bonded. This is a particularly a problem with limestone and rocks derived from it, such as marble. The basic constituent of limestone is calcium carbonate, which is very vulnerable to acidic compounds.Know More
Acid rain is created when industrial and other modern processes release sulfur compounds into the atmosphere. These react with water, creating sulfuric acid, the major active constituent of acid rain. This dissolved acid is carried with rain onto limestone or marble, and the calcium carbonate in the rock reacts with it. This reaction generates water, carbon dioxide, calcium ions and sulfate ions. All these products are then carried away with the flowing rainwater. This both erodes natural and man-made structures made of limestone, and depletes soil of important calcium compounds.
Acid rain also harms the environment in other ways. Acid rain accumulates in bodies of water, such as lakes, making them more acidic. This can make lakes so acidic they no longer support most fish and other types of organisms. In addition, the dissolution of calcium and other compounds in soil can release toxic aluminum and other ions into the environment.Learn more about Erosion & Weathering
Wind erosion happens when pieces of the Earth are worn away by strong winds over time, and water erosion happens when moving water such as ocean waves wear away rock instead of seeping into the ground. Water is a more powerful erosion force than wind.Full Answer >
Gravity causes erosion by pulling dirt, rocks and soil downward. For example, as water mixes with dirt to form soft mud, the mud cannot support itself against the force of gravity.Full Answer >
Waves cause erosion by moving sand and debris during storms and other events, as they break higher than normal on the beach, pulling sand back into the water with them. Human interventions and major weather events such as tropical storms and hurricanes erode beaches in this way.Full Answer >
Three main natural forces bring about erosion: wind, water and ice. When water flows and moves heavily, it can cause soil erosion. Strong winds, especially in the desert, erode sand dunes. Glacial erosion has significantly shaped the surface of the earth for millions of years.Full Answer >
