The movement or falling of the material is relatively short, and it can be only few ten meters, or few hundred meters. The slumps occur suddenly, usually without any warning sign, apart from the loud cracking noise few seconds before the material moves or falls down.
As for your first question,
When created in non-volcanic areas, water becomes heated as it comes into contact with hot rocks within the earth's crust. Then the water will rise back up to create hot springs. The volcanic activity responsible for creating the hot springs<span> are caused by the moving </span>hot<span> spot, which is currently under </span>Yellowstone<span>.

As for your second question,
Balneology is the practice of treating and preventing disease through the use of natural mineral hot springs<span> water. That's a use of hot springs.</span>
Winter. It can kill plants, livestock; and re-shape the surrounding area.
Plate tectonics are important to geoloigists because they explain how the continents make up the earths crust.
