WE+ALREADY+KNOW

-what caused the quake -tsunami caused by quake -The quake was a 8.9 -The sound of furniture falling in houses was almost deafening -Killed thousands of people. -Japan has emergency workers from different countries. -Most buildings, cars, ext. were destroyed. -Nuclear explosion. -Dangerous gases in the air. -They are covered in mud and debris. -Japan is highly populated. -Japan has walls 20 feet high to stop tsunamis like this even though this tsunami was 30 feet high. -Sirens went off to warn Japan of a tsunami coming their way. -the highest possible earthquake on a rictor scale is a 10. - there was so much kinetic energy the earthquake caused a tsuami. -There was an earthquake in missouri -Nuclear reactors were set off by quake. -A tsunami can't affect Missouri. -There is a earthquake somewhere in the world every 30 seconds.
 * What We Know**

-The closest nuclear reactor is the cooper reactor 70miles away. -Another close reactor is Ft. Calhoun a little north of omaha.

//Buildings get destroyed from earthquakes.// //over 2000 people are missing since tsunami.// //Water is all over Japan.// //The longer the fault is the bigger the quake is.// //Many buildings in Japan weren't made structurally for earthquakes.// //Earthquakes happen when fault lines break.// //In iceland tectonic plates move away from eachother.// //Engineers make simulated earthquakes to see what type of structure works and which one dosent.// //The san Andreas fault line moves past each other creating earthquakes.// //Experts are asking when the big earthquake will strike.// //The closer a building is to a fault line the harder and more violently it will shake during a quake.// //Tectonic plates moving toward each other created mountains such as the Himylayin mountains.// In Iceland the plates move away from each other(talk about your personal space) The California and LA quakes are due to the plates moving against each other. The closer and taller the building is to the center of the quake, the longer and harder it will shake. The fault line in California has almost a century of energy to release. Natural disasters possible in MO are: Earthquakes, floods, storms, heat waves, tornadoes, hail storms, ext. Not all of Japan was affected by the earthquake. Northern Japan was the part mostly affected.

__** BASIC THINGS ABOUT OUR EARTH THAT WE KNOW: **__ INNER CORE- extremly hot solid sphere. mostly iron and nickle at the center of the earth. OUTER CORE- only liquid layer of the earth. its a sea of iron and nickle. MANTLE- subdivided into two regions upper and lower. made of hot semisolid rock located directly below the crust. CRUST- hard and rigid, earth's outer most and thinest layer. PANGEA- how all the continents were once touching. and once the tectonic plates move, they moved the contenents far apart to where they are today. CRUST AND TOP OF MANTLE- (where we stand) = lithosphere. the big chunks of the lithosphere are what we call tectonic plates. Asthinosphere- part of mantle= semisolid. EVERY 30 seconds there is an earthquake somewhere around the world. EARTHQUAKES are caused because the tech. plates (solid) are laying on something NOT solid. BIG IDEA: plates move because of uneven heating in the mantle. uneven CONVECTION!:))) THICK PLATES UNDER CONTINENTS- CONTINENTAL PLATES THIN LESS DENSE PLATES UNDER OCEAN- OCEANIC PLATES 2 thick plates converging -><- =mountains. 2 plates rubbing together side by side- earthquake.(or seduction) 2 plates divergent plates <- -> moving away from eachother- trench/ridges We have had tornados, floods, and snow storms fault- crack in the crust of the earth.  transform boundary called san andres. every time there is an earthquake in California, L.A. area moves south. This fault divides the pacific plates and north american plate.  transform boundary- moderate to strong earthquake. strike slip faults are found here. when two plates slide past eachother. convergent boundary- deep strong quakes. example: under japan. where volcanic islands are formed. mnts. trenches formed here. REVERSE faults here. When two plates collide. divergent boundary- mid ocean ridges weak shallow earthquakes. as these boundaries move magma comes up from the mantle cooling and forming new rock or crust/ ocean floor. this is a.k.a. normal fault. when plates move away from eachother. -with every move/break in the earth's crust, energy radiates out in seismic waves. in every earthquake, there are different types of seismic waves. BODY WAVES. SURFACE WAVES. PRIMARY WAVES. SECONDARY WAVES. faults are cracks in the earths crust. BODY WAVES- travel through the inner part of the earth. SURFACE WAVES- travel over the surface of the earth. sometimes called LONG WAVES or SIMPLY L WAVES, are responsible of damage from earthquakes, because they cause most intense vibrations. surface waves stem from body waves that reach the surface. FAULT IN MO- the new maderine. place where earthquakes originate-focus pinpoint on the map where they LOCATE earthquakes= epicenter. epicenter= right above the FOCUS.
 * deeper into the earth= more thermal energy.
