Mountains I. INTRODUCTIONAmountain is an elevated land mass usually higher than its surroundings. Some are isolated, but they usually appear in ranges(MsBs95W32). A group of ranges closely related in form, origin, and alignment is a mountain system; an elongated group of systems is a chain; and a complex of ranges, systems, and chains continental in extent is a cordillera, zone, or belt.(MsBs95W32). Some mountains are remains of plateaus, mesas, and buttes, through erosion(Summerfield). Other

Earthquakes Describe the frequency, origin and distribution of earthquakes at mid-ocean ridges, ocean basins, subduction zones and continental shields. Earthquakes are happening almost everyday all over the world. Most of the time earthquakes are not strong enough to be felt by people, but the shaking caused by an earthquake is recorded by a seismogram. These are located all over the world at different points. Only occasionally will a larger magnitude earthquake strike and cause damage to the re

Where Do Earthquakes Happen? Earthquakes occur all the time all over the world, both along plate edges and along faults. Along Plate Edges Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The plates under the oceans are called oceanic plates and the rest are continental plates. The plates are moved around by the motion of a deeper part of the earth (the mantle) that lies und

Messina Earthquake in 1908
Messina Earthquake in 1908 On December 28, 1908 an earthquake occurred along the Straits of Messina between the island of Sicily and mainland Italy, measuring between M6.7 and M7.2 on the magnitude scale. The ground shook for 30 to 40 seconds, and the destruction was felt within a 300 km (kilometer radius. The Messina Earthquake caused severe ground shaking throughout the region and triggered a local 12 m (meter) tsunami, which struck within minutes after the earthquake. It took some 100,000 to
