Sinkholes form when water erodes the supporting bedrock away. They are more common in areas where carbonates, including dolomite and gypsum, formed as water evaporated to create bedrock.Know More
Carbonates are highly soluble in acidic aqueous solutions, including acid rain. Acid rain causes channels to form within the bedrock and subsequent rainfall continues the erosion process. As channels grow larger, some combine until the underlying structure collapses. Without the support of bedrock, the upper layers of soil collapse into the hole, forming the sinkhole.
One area that sinkholes are common is Florida, because of the abundance of marshlands and frequent rains. However, sinkholes do form in many areas across the United States.Learn more about Erosion & Weathering
Acid rain contaminates water and soil, killing microbes, insects, fish, and other aquatic wildlife and vegetation. It corrodes stone and metal, and it damages automotive paint. Although contact with acid rain is not directly harmful to people, it can indirectly cause health problems.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 >
Weathering occurs when materials are eroded or broken down by natural means, such as ice, water and wind. Acid, plants and animals can also cause weathering.Full Answer >
Running water causes erosion through friction. Additionally, running water can carry dust, silt or sand particles, which may also work to erode a given surface. Typically, water erodes surfaces in one of four ways.Full Answer >
