Worksheet for Video - 10 Things You Didnt Know About Earthquakes

The ground shakes, buildings tumble and the world heaves and cracks. Serious earthquakes are terrifying and unsafe, but are rare in the U.S. But why practice earthquakes happen? The globe is made up of four layers – the inner core, outer core, mantle and chaff. The mantle and crust are a thin skin compared to the other layers.

The mantle is about 1,750 miles thick, while the crust is only almost viii miles thick. This sparse skin is broken into pieces chosen tectonic plates. The plates are like puzzle pieces, floating on top of the Earth's inner core. Sometimes the pieces slide under or against each other and become stuck.

When the pieces slide apart, they create tremendous force. This force causes the globe to milk shake and ripple. Over 80 percent of the earth'due south earthquakes happen in the Pacific Ocean, in a place known as the "Band of Burn." Annually, around 10,000 people die in earthquakes every year. Most of the deaths happen when people are trapped in falling buildings. Afterwards an convulsion, mudslides, fires and tsunamis tin can as well hurt people.

Seismologists tin can tell how serious an earthquake is by a machine called a seismograph, which rates the intensity of the convulse'south shaking.

Fun Facts All Nigh Earthquakes for Kids

• Alaska, California and Hawaii have the near earthquakes in the U.Due south. Other western states, like Nevada, Idaho, Washington and Oregon are prone to earthquakes or can be damaged by earthquakes that happen in Alaska and California.
• Alaska has more earthquakes than any other U.S. state. It has experienced over 12,000 earthquakes in the last 30 years. Alaska is followed by California, Hawaii, Nevada, Washington, Idaho, Wyoming, Montana and Utah.
• Underneath the World'due south surface lie tectonic plates. These plates motility and shift over time. Sometimes they slide under one another or button upwardly against each other, creating enormous stress. When they motility again, they cause an earthquake.
• Scientists who study earthquakes are chosen seismologists.
• Seismologists can tell how serious an earthquake is past a auto chosen a seismogram, which rates the intensity of the convulse'southward shaking.
• Scientists can use special instruments to record an earthquake's strength. An earthquake rated three to 5 is minor; an earthquake rated v to 7 is moderate to stiff; an earthquake rated vii to 8 is major; an convulsion rated eight or to a higher place is great.
• On average, one earthquake measuring 8 or above happens every year.
• The surface area near Japan in the Pacific Ocean has the most earthquakes in the earth. This area also has a lot of volcanoes. Information technology is called the Ring of Burn down.
• Most people who die in earthquakes die when buildings plummet on them. Others die in floods, fires or mudslides that happen afterward the earthquake.
• May 22nd 1960 in Valdivia Chile the largest e'er recorded Earthquake measuring a whopping 9.v magnitude struck.
• December 26th 2004 an Earthquake in the Indian Ocean measuring a magnitude of nine.1 on the Richter Scale resulted in a massive Seismic sea wave hitting the region which resulted in the deaths of over 230,000 people.
• March 11th 2011 off the declension of Honshu Japan a magnitude 9.0 convulsion acquired a massive Tsunami to striking the coast. The Tsunami caused over xviii,000.
• On our planet earth we have 4 different types of dip-slip-faults and they are Normal – Reverse – Thrust – Strike Up.
