Sinkhole
A sinkhole, also known as a sink, shake hole, swallow hole, swallet, doline or cenote, is a natural depression or hole in the earth's surface caused by karst processes - the chemical dissolution of carbonate rocks[1]. Sinkholes may vary in size from less than 1 to 300 meters (3.3 to 980 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. They may be formed gradually or suddenly, and are found worldwide. These terms are often used interchangeably, though many distinguish between features a surface stream flows into and features with no such input. Only the former are described as sinks, swallow holes or swallets. A sinkhole on a glacier is called a moulin or a glacier mill.

Sebuah lubang pembuangan, juga dikenal sebagai wastafel, lubang goyang, menelan lubang, swallet, doline atau cenote , adalah depresi alami atau lubang di permukaan bumi disebabkan oleh proses Karst - pembubaran kimia batuan karbonat [1] . Sinkholes may vary in size from less than 1 to 300 meters (3.3 to 980 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes dapat bervariasi dalam ukuran dari kurang dari 1 sampai 300 meter (3,3-980 kaki) baik dalam diameter dan kedalaman, dan bervariasi dalam bentuk dari tanah berlapis batuan dasar mangkuk ke jurang bermata. They may be formed gradually or suddenly, and are found worldwide. Mereka mungkin terbentuk secara bertahap atau tiba-tiba, dan ditemukan di seluruh dunia. These terms are often used interchangeably, though many distinguish between features a surface stream flows into and features with no such input. Istilah-istilah ini sering digunakan secara bergantian, meskipun banyak membedakan antara fitur mengalir aliran permukaan ke dalam dan fitur tanpa masukan seperti itu. Only the former are described as sinks, swallow holes or swallets. Hanya mantan digambarkan sebagai sumuran, menelan lubang atau swallets. A sinkhole on a glacier is called a moulin or a glacier mill . Sebuah lubang pembuangan di gletser disebut moulin atau pabrik gletser .
Mechanisms
The mechanisms of formation involves natural process of erosion[2] or gradual removal of slightly soluble bedrock (such as limestone) by percolating water, the collapse of a cave roof, or a lowering of the water table. Occasionally a sinkhole may exhibit a visible opening into a cave below. In the case of exceptionally large sinkholes, such as Cedar Sink at Mammoth Cave National Park, USA, a stream or river may be visible across its bottom flowing from one side to the other.
The sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by circulating ground water. As the rock dissolves, spaces and caverns develop underground. These sinkholes can be dramatic because the surface land usually stays intact until there is not enough support. Then, a sudden collapse of the land surface can occur.
Sinkholes can be human-induced and new sinkholes have been correlated to land-use practices, especially, from ground-water pumping, construction, and development practices. They can also form when natural water-drainage patterns are changed and new water-diversion systems are developed. Some sinkholes form when the land surface is changed, such as when industrial and runoff-storage ponds are created; the substantial weight of the new material can trigger an underground collapse of supporting material, thus, causing a sinkhole.
