Volcano

A vent or opening in the earth's crust through which molten lava, gases, and other materials issue from the earth's interior. Volcanos form when molten rock called magna, rises through the earth's crust to the earth's surface. Volcanos emit gaseous, solid, and liquid products. Lava can flow as fast as 20 mph and as far as 60 miles. There are 5 types of eruptions:

pelean - lava bursts with almost no flow of liquid lava.
vulcanian - most of the material is ejected.
strombolian - frequent and regular ejection of hot, flowing lava fragments and clouds of gases with little ash or dust.
hawaiian - large amounts of lava are released with virtually no explosive action.
icelandic or fissure - an enormous outpouring of lava from a long fissure or system of long fissures, spreading over great distances, in thick layers, forming plains or plateaus.

Volcanos . . .

erupt slowly or without warning,	cover large areas with ash,
destroy cities,	and erase life in hot lava.

Did you know: There are so many volcanos fringing the Pacific Ocean that the region is sometimes referred to as the Ring of Fire. In 1943, Paricutic began erupting from a cornfield in Mexico and, within one year, a cone rising 1,500 feet above the surrounding land had been formed.

Waterspout

A whirlwind over water, usually shaped like a funnel or ropelike cloud. Waterspouts typically occur during fair weather over warm waters in the tropics or sub tropics when a strong current of warm air rises from near the surface of the water.

Waterspouts . . .

are funnels of water	capable of destroying
coast line cities	and relocating marinas.

Did you know: If a waterspout touches land, it is called a tornado.
