A sinkhole is what happens at the ground surface when a cave roof collapses into a cavern beneath it. This is easy to imagine if, say, the cave is only ten feet below ground. ... Once that happens the soil will begin to fall downward into the cave like water flowing down a drain (though slower).

A sink drains by way of several components. Kitchen sinks have a strainer fitted into a strainer body that's inserted down through the sink hole and sealed to the sink with a bead of plumber's putty. Beneath the sink, the strainer body connects to the drain's tailpiece and the rest of the drain plumbing.

In most landscapes the land is not perfectly flat—it slopes downhill in some direction. Flowing water finds its way downhill initially as small creeks. As small creeks flow downhill they merge to form larger streams and rivers. Rivers eventually end up flowing into the oceans.

Man-made causes of sinkholes result from activities such as construction, mining, broken water/sewer pipes, heavy traffic, or failure to compact soil properly after excavation. Sinkholes can also occur when the land surface has changed such as flooding.

Geologists have offered various theories for the natural causes of sinkholes such as the type of soil / rock giving way to rainwater and underground water. Other natural causes submitted by experts include heavy rainfall, global warming, underground gas explosions, etc.

A sinkhole may form by collapse into subterranean voids created by dissolution (the dissolving) of limestone or dolostone or by the subsidence as these strata are dissolved.” “Catastrophic ground cover collapse” is defined as “geological activity that results in all of the following: 1).

A small sinkhole with minimal damage to the structure may cost anywhere from $10,000 to $15,000. However, sinkholes that cause extensive damage and need a significant amount of work to repair or revive the structure, may be much pricier, costing anywhere from $20,000 to $100,000, or more.

Weathering and erosion can create caves, arches, stacks and stumps along a headland. Caves occur when waves force their way into cracks in the cliff face. ... The stack will be attacked at the base in the same way that a wave-cut notch is formed. This weakens the structure and it will eventually collapse to form a stump.

It's been more than 50 years since anyone ventured to the deepest spot on earth. There's a simple reason. 7 miles is a long way down. It'll take James Cameron about 90 minutes to touch bottom.

Bottom spots are a little different, as Dr Serrano explains; "Spots on your bottom are likely to be caused by folliculitis, a condition that occurs when bacteria and dead skin cells get into your hair follicles, causing inflammation. This usually looks like small red bumps clustered around the follicle."

Gophers easily den beneath the bathtubs are most of them do not have concrete under them. After a few days of burrowing from them, the backfill from the tunnels leads to swelling in the walls and foundation.

Minerals that are carried in groundwater can also be deposited in other places. This cycle of erosion and deposition can cause underground caves to form. This happens especially in areas where there is limestone below the surface.

Garbage disposals are connected to your sink with a flange and/or plumber's putty. ... If your garbage disposal is leaking out of the bottom (and not from higher up and just dripping to the bottom), the most likely cause is the actual garbage disposal itself. There are internal seals that wear out over time.

When the water is rushing into the sink and overwhelms the main drain, the holes help drain water that has reached the top of the basin. However, as anyone who has experienced an overflowing sink knows, the holes are not a guaranteed way of preventing a flood. They are usually significantly smaller than the main drain.
