When water slowly bubbles underground, it can form geysers or hot springs. Geysers erupt intermittently, releasing steam and water into the air, while hot springs have a constant flow of warm water to the surface. Both are caused by underground volcanic activity or geothermal heating.
The Fugitive Slave Act caused the formation of the Underground Railroad.
water accumulation is caused by underground atmosphere eg ;reaction of acids in carbonates,gases like hydrogen sulphide because normally it is associated with stagnant water,heat and the vapours.So it appears like fog or mists in underground.
Underground water is called underground water, because it is "underground" not because it is fresh or salt. You can have underground salt water reservoirs just like you can have fresh water ones.
Subsidence of land at the surface, and damage to dwellings. Lung diseases caused by conditions underground. Air and water pollution from the coal-tips.
Yes, erosions can happen underground through processes such as underground water flow dissolving rock formations, cave formation through solution erosion, and soil erosion caused by water movement in underground aquifers. These processes may lead to the formation of caverns, tunnels, and other underground features over time.
An underground aquifer would provide the best protection against a water shortage caused by drought.

Underground water is cleaner.
you know when there is water underground when you here the sound of water...(underground)...or see water on your lawn when there is no liquid to be found... : )
what is the upper surface of ground water
