Under the ground are large bodies of water called aquifers. They are reservoirs of water that have been absorbed over many many years. The size of these reservoirs depends on factors such as rainfall, humidity, and temperature in a particular geographic location.

When water is pumped out of the ground by wells, this makes the earth surrounding the aquifers less stable. Sink holes are extreme examples of the unstable earth below the surface. The earth eventually caves in due to the unstable layers of soil and the massive weight of the soil, a sink hole is born.

A sink hole is a hole that forms naturally on the surface of the Earth. They have many different sizes, both in depth and diameter. In addition, they can form very quickly or very slowly, without warning. They are also found all over the world. They are caused by a dissolution of bedrock, usually carbonate rock like limestone. This is often caused by erosion. Sink holes have also occurred due to a collapsing cave.

Sink holes have engulfed entire homes and buildings, even leaving people seriously injured or dead.

It is a hole, that is caused by a natural depression on the earth's surface, that is formed through the dissolution of rocks- usually made up of carbonates from limestone. They vary in sizes, in diameter, area and also in depth. They can be found worldwide, in places like Florida (many of them) and also in Mexico (Zacaton). It can cause flooding and severe damage if overflowed.
