Hot spring

From ArticleWorld


A hot spring is a place where warm or hot water issues from the Earth, for at least a regular part of the year, and is significantly above the normal ground temperature. The water is naturally heated, either by geothermal heat from the Earth’s interior, or by the water coming in contact with the magma in volcanic zones.


Therapeutic uses

Heated water can hold more dissolved solids. Warm, and especially hot springs, also often have a very high mineral content, containing everything from simple calcium to lithium, and even radium. As a result of both the folklore, and the proven medical value some of these springs have, they are often popular tourist destinations, and locations for rehabilitation clinics for those with disabilities.


Hot springs in the United States

Several national parks in the United States feature hot springs, including Hot Springs National Park in Arkansas and Yellowstone National Park in Montana. In addition to the national parks, hot springs can be found as far north as Alaska, and as far south as New Mexico.


Places

Cities that have hot springs are often referred to as spa towns. There are many spa towns throughout the world. The United States, Germany, the United Kingdom, Italy, France, Australia, Japan and Greece, as well as others, all boast spa towns.
