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
The World's Deadliest Animals Might Surprise You| Sciencing
Boxelder bugs, (Boisea trivittatis), congregate in large numbers on the sides of homes and buildings to sun themselves. Populations explode after a number of warmer than usual winters becoming a nuisance to homeowners by their sheer numbers. There are few natural predators of these relatively harmless bugs and even fewer that homeowners want in their yards. Rodents, a limited number of other insects and a few bird species will eat boxelder bugs but there are a number of other control methods ...| 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

Earth's poles are the coldest places on the planet, with the South Pole outpacing the North Pole in terms of bone-chilling weather. The lowest temperature ever recorded was in Antarctica, about 700 miles (1,127 kilometers) from the South Pole. The reason why it's colder in the Antarctic than the Arctic is because it's dry and mountainous. Two of the coldest places in the Northern Hemisphere are populated, and they aren't very close to the North Pole.| Sciencing
