Rainwater affects the establishment of the phenomenon Sinkhole: Ok techno



JAKARTA – Residents of Kadudampit Village, Sukabumi Regency and West Java were shocked by the apparition of a mysterious giant hole that gaped. The hole is located in the middle of people's rice fields.

The hole is a phenomenon called sink. Reports from Science.howstuffworksOn Monday (04/29/2019), the sink is a geological feature, a formation that is more than just a hole in the ground.

Although many are less than 30 feet deep, the holes can look like lakes, cover hundreds of miles or quietly in your backyard.

Wells are generally formed by erosion caused by frequent exposure to water. Most holes occur in areas where the rocky bed is formed of minerals and soft rocks, such as salt, gypsum, limestone, dolomite or others that belong to the class of evaporating rock or carbonata.

The holes usually develop slowly because the bedrock is removed by the acidic water because it absorbs carbon dioxide and interacts with the plants. Rainwater clearly plays a role, but invisible water is also important.

When the acidic water dissolves the stone, it sculpts a channel, or underground channel, into the water. This channel, in turn, helps develop an underground basin known as a recharge area.

The areas of infiltration contribute to the formation of holes because the water flows and them to the surface, eroding the rocky bed. When water floods a developing well, part of the soil and other materials are in the canal, retaining even more water and limiting its ability to seep out.
