Ulusal Corvette Müzesi altında bir subatan oluştu ve sekiz arabayı yuttu. - A sinkhole formed under the National Corvette Museum and swallowed eight cars.
Bu subatanlar saatli bombadırlar. - These sinkholes are time bombs.
A depression in the land surface formed either by collapse of the roof of an underground cavern or channel or by solution of near-surface limestones or similar rocks
A pit like hole in found in areas of karst These features are caused by the weathering of limestone or dolomite by subsurface drainage Also called a sink or doline
a depression in the Earth's surface caused by dissolving of underlying limestone, salt, or gypsum Drainage is provided through underground channels that may be enlarged by the collapse of a cavern roof
or sink or doline Depression formed as underlying limestone bedrock is dissolved by groundwater. Sinkholes vary greatly in area and depth and may be very large. The two main varieties are those caused by the collapse of a cavern roof, and those caused by the gradual dissolving of rock under a soil mantle. Collapsed sinkholes generally have steep rock sides and may receive streams that then flow underground. Soil-mantled sinkholes are generally shallower; they may become clogged with clay and hold a small lake
A steep-sided depression formed when removal of subsurface embankment or foundation material causes overlying material to collapse into the resulting void Seepage through the limestone foundation at Horsetooth Reservoir has caused sinkholes at the south end of the reservoir near the Swim Beach and also one sinkhole near the upstream face of Horsetooth Dam All sinkholes have been filled and capped
Strictly, a hole or doline (qv) which acts as a streamsink Unfortunately, the word has become debased by common misuse as a synonym for a doline (qv), especially a collapse doline
A closed depression formed either by solution of the surficial bedrock (e g , limestone, gypsum, or salt) or by collapse of underlying caves Complexes of sinkholes in carbonate-rock terrain are the main components of karst topography
A basin- or funnel-shaped hollow in limestone, ranging in diameter from a few meters up to a kilometer and in depth from a few to several hundred meters
A depression in a karst area, commonly with a circular pattern Its drainage is subterranean, its size is measured in meters or tens of meters, and it is commonly funnel-shaped From Glossary of Geology, 4th Edition, 1997, American Geological Institute
a natural depression in a land surface indicating a subterranean passage, generally occurring in limestone regions and formed by solution or by collapse of a cavern roof
Over long periods of time groundwater may dissolve large areas of limestone rock, slowly enlarging underground caverns and eroding support for the land above There may be no evidence of what is taking place until the ground collapses abruptly into a void below, producing a sinkhole
