What can help a sinkhole?
Sinkholes may capture surface drainage for running or standing water, but may also form in currently high and dry locations. The state of Florida in the USA is known for having frequent sinkholes, especially in the central part of the state. The Murge area in southern Italy also has numerous sinkholes. Sinkholes can be formed in retention ponds from large amounts of rain. Sinkholes are usually but not always linked with karst landscapes. In such regions, there may be hundreds or even thousands of sinkholes in a small area so that the surface as seen from the air looks pock-marked, and there are no surface streams because all drainage occurs sub-surface. Sinkholes have been used for centuries as disposal sites for various forms of waste. A consequence of this is the pollution of groundwater resources, with serious health implications in such areas. Sinkholes also form from human activity, such as the rare but still occasional collapse of abandoned mines in places like West Virginia, USA. More commonly, sinkholes occur in urban areas due to water main breaks or sewer collapses when old pipes give way. They can also occur from the overpumping and extraction of groundwater and subsurface fluids. The Great Blue Hole, located near Ambergris Caye, Belize. Many sinkholes are also found in Northern Michigan. These are prominent in Alpena County in Northeast Michigan. In Lachine,Michigan there are five sinkholes that are found to be very deep , and within two miles of each other. Alpena's visitor information cites their sinkholes as an attraction for visitors to the area. In August 1998 a 16 year old Alpena boy survived a 200+ foot fall in an open sinkhole 3/4 a mile off of Leer road in Lachine, Michigan (The Alpena News 8-21-1998). A majority of sinkholes in Alpena are also found underwater. Many divers explore these on a regular basis. When sinkholes are very deep or connected to caves, they may offer challenges for experienced cavers or, when water-filled, divers. Some of the most spectacular are the Zacatón cenote in Mexico (the world's deepest water-filled sinkhole), the Boesmansgat sinkhole in South Africa, Sarisariñama tepuy in Venezuela, and in the town of Mount Gambier, South Australia. Sinkholes that form in coral reefs and islands that collapse to enormous depths are known as Blue Holes, and often become popular diving spots.

In the United States, the most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania. The overburden sediments that cover buried cavities in the aquifer systems are delicately balanced by groundwater fluid pressure. The water below ground is actually helping to keep the surface soil in place. Groundwater pumping for urban water supply and for irrigation can produce new sinkholes in sinkhole-prone areas. If pumping results in a lowering of groundwater levels, then underground structural failure, and thus, sinkholes, can occur.
Which is the largest groundwater deposit in the world?
Great Basin Aquifer
What do sinkholes provide?
Sinkholes lead to many great things like caverns and other underground sources like aquifers. When a sinkhole is discovered, entrepreneurs flock to the area to claim the land it is on or buy the land. Some sinkholes have been searched and have had beautiful underground caverns that can be used as a tourist attraction. Also sinkholes that have rising and falling water levels could actually be an opening to an aquifer. If the aquifer is not discovered yet you can set up a pretty good water bottle business. To sum it up, sinkholes provide us with beautiful views and something to drink. Some sinkholes have been searched and have underground rivers. There is one sinkhole in China that has a forest at the bottom. It is home to many rare plants and animals. The Chinese have also found a few leopards down there that are rare. Sinkholes can house the most unlikely things, like your house, when a sinkhole opens up under it.

What are the benefits of newtonian fluid?
Newtonian fluids are the most accurate way to measure the thickness of a liquid. Mathematics are involved in the calculations. The fluids are named for the great scientist Isaac Newton.
What is a groundwater system?
"Groundwater flow is the movement of water that travels and seeps through soil and rock underground. Stored in cavities and geologic pores of the earth's crust, confined groundwater is under a great deal of pressure. Its upper part is lower than the material in which it is confined. Unconfined groundwater is the term for an aquifer with an exposed water surface."
What are some of the central values and beliefs that helped shape the emerging culture of the American colonies?
That they no longer wished to be owned by and work for the benefit of Great Britian.

Where are the sink holes in Florida?
Correction Q:) Do sinkholes occur in the Florida Peninsula often? A.) Well, not "often" but once in a great while, due to the land formations of the undersides of the Florida Peninsula. Source(s): Proud Tampa, FL Resident
Is the Great Artesian Basin a desert?
No - Australia's Great Artesian Basin is a huge underground water supply. Occupying an area one-fifth of Australia's size, it is one of the largest artesian groundwater basins in the world. It is quite different to North America's Great Basin Desert.
