The viscosity of a fluid refers to how easily it moves under stress. A highly viscous fluid will move less readily than a fluid of low viscosity. The term fluid refers to liquids and gases both of which have viscosity. The accurate prediction and measurement of the behavior of a fluid in motion is essential in the design of efficient industrial plants and apparatus.| Sciencing
Before the 20th century, people did not know that the continents moved around the planet. Continental drift is such a slow process that you can't see land masses shift with the naked eye. Because the continents never stop moving, however, the world map you know today will not look the same in the distant future.| Sciencing

Mount St. Helens is an active volcano located in southern Washington state. Its most famous eruption on May 18, 1980, killed 57 people, destroyed 250 homes, and caused billions of dollars worth of damage. It was the most destructive volcanic event in American history. Fortunately, however, there was a great deal of activity in the months before the eruption. Nearby communities, as well as the rest of the nation, had plenty of warning that a major eruption was coming.| Sciencing
Volcanoes are one of nature's most destructive forces. However, volcanoes are also one of nature's chief constructive forces. Volcanic eruptions are responsible for creating new crust and geological landforms. The specific results of a volcanic eruption differ widely; each volcano type has a distinct eruptive nature.| Sciencing
