The causes of sinkholes consist of karst processes such as the chemical dissolution of carbonate rocks and suffusion processes. The formation of sinkholes involves the processes of erosion. Sinkholes develop due to surface drainage or running water. Though dry places are thought to have less water, sinkholes can develop in these areas as well as long as the correct conditions come into play. They can form from human activity as well like abandoned mines, pipelines and sewers. Sinkholes are most common in states such as Alabama, Florida, Kentucky, Missouri, Pennsylvania, Tennessee and Texas. Places with sandstone and quartzite terrains where the rock below the land surface is limestone or any other carbonate rock that can be dissolved by ground water. When the rock below the surface layer dissolves, spaces and caverns form underground. Sometimes it can take months or even years for these caverns to form completely before the ground becomes too weak and collapses suddenly. There are two main types of sinkholes. The most dangerous type of sinkhole is the cover-collapse sinkhole. This sinkhole shows up unexpectedly and can swallow cars, buildings and even people whole. Cover-collapse sinkholes are the types of sinkholes that
