Sinkhole - Wikipedia A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer The term is sometimes used to refer to doline , enclosed depressions that are also known as shakeholes , and to openings where surface water enters into underground passages known as ponor , swallow hole or swallet
What is a sinkhole? | U. S. Geological Survey - USGS. gov A sinkhole is a depression in the ground that has no natural external surface drainage Basically, this means that when it rains, all of the water stays inside the sinkhole and typically drains into the subsurface Sinkholes are most common in what geologists call, “ karst terrain ”
Sinkholes | U. S. Geological Survey - USGS. gov A sinkhole is an area of ground that has no natural external surface drainage--when it rains, the water stays inside the sinkhole and typically drains into the subsurface Sinkholes can vary from a few feet to hundreds of acres and from less than 1 to more than 100 feet deep
Sinkhole - National Geographic Society A sinkhole is a hole in the ground that forms when water dissolves surface rock This sinkhole sits in the Yucatan Peninsula in Mexico Natural sinkholes in limestone, like this one, are called cenotes People of Mexico have been using the freshwater that collects in cenotes since Maya times
Sinkholes: causes, risks, and how to prevent them Sinkholes are enclosed depressions commonly formed by the subsurface dissolution of soluble rocks and or the downward displacement of materials These processes can lead to ground settlement or sudden surface collapse
Sinkholes: What They Are, How They Form, And Their Potential Dangers Sinkholes are sudden depressions or holes that appear on the Earth’s surface when the ground collapses These phenomena can cause significant damage to infrastructure and pose serious risks to human safety
Sinkhole Facts - Science Notes and Projects A sinkhole is a depression or hole in the ground caused by the collapse of a surface layer, often due to the dissolution of underlying soluble rock such as limestone, dolomite, or gypsum These natural or manmade formations vary in size, shape, and depth, appearing suddenly or developing gradually over time
Sinkholes: Causes, Types, Formation and Effects As the name suggests, sinkholes involve land sinking, causing holes on the ground These depressions or voids form when water erodes an underlying rock layer, particularly in cases where the rock consists of limestone, salt beds, or carbonate rock
