good morning 4th grade is this is yours science video for Wednesday so today we are continuing the outline that we started yesterday 100 in the packet and yesterday we started the page 99 which was the beginning of the outline continues on to page 100 and we left off in this section of the book page 250 and 251 more questions that go with these Pages never going to want to turn the page to get to the next heading about tsunamis stop earthquakes vibrations of an earthquake are strongest where the earthquake blank and so if we look at the paragraph over here we can find almost that same sentence the vibration earthquakes are strongest where the earthquake first begins first where the earthquake first begin the epicenter first earthquake vibrations through Earth's crust in blank like ripples from a pebble dropped in a pond so we where is the epicenter of the earthquake starts at vibrations move out in all directions from where it starts and their strongest where it begins the vibrations move through Earth's crust in all directions there it is in the text so through Earth crust in all directions okay so next what is the synopsis to the section on tsunamis what is a tsunami a giant ocean wave called a blank earthquake blank so let's see what we can find that a giant ocean wave called a tsunami structure is usually caused by an earthquake on tsunamis are usually caused by an earthquake on the ocean floor so caused by an earthquake on the ocean 4 as a tsunami moves closer to shore it slows and gets so as it moves closer to shore this is a diagram we looked at when we read it slows down and get us a crown goes up towards the shore the wave actually becomes it's supposed to say higher because I think when I was reading the text as the wave moves closer to the store it dragged the ocean floor this Lowe's wave down fire Toonami maybe one blank of water or a series of blank a tsunami can either one large wave or I can be a series of smaller waves let's find where they talk about that in the text as soon as he can cause a break sometimes a tsunami is one huge wall of water a tsunami maybe one huge wall is water or a series of at other times it may be a Siri smaller waves what are some safety tips for earthquakes and tsunamis and there it is what are some safety tips for earthquakes and tsunamis your family should hold blank and arrange a blank you're home for when the earthquake is over just like when you're in school and we've drilled at school your family should hold and earthquake drill what your family is going to do and arrange a blank outside your home for when the earthquake is over whole family earthquake drills you want to write hear a range of place outside your home so if you exited the home through different stores a different just know where to find each other so you need a meeting place people making out you have a meeting place outside outside if you're outside during an earthquake you should move quickly to an blank and if in a car you should not stop underage so let's look at where they talk it's about being outside outside during a space you should move quickly to open space and if you're in a car you should not stop a blank if you are in a car the driver should stop driving but never stop under a tree or Bridge should not stop under a tree Corbridge if you live near the coast you should listen for tsunami advisories watches and warnings after an blank so we know that tsunamis almost always follow Underground underwater earthquake so you should listen for a tsunami advisories after an earthquake that I posted on one of the websites was the Pacific tsunami warning center and when there is earthquake is probably shouldn't have much to tell you when you visited on Monday but if there ever is a big earthquake in the Pacific Ocean near California Terry or it may say small tsunami could happen in certain locations it's a good site to check after there's an earthquake is there is a tsunami warning in your area you should blank right away so what do you do if there is a tsunami warning you need to move Higher Ground right away why do earthquakes occur so earthquake basically because the Earth's crust is made of plates place will slip and slide against each other either into or away from one another like that it caused operation to shortest route to shake the Earth's crust so what's the Earth's plates against each other along false and librations that shake herbs cancel there's a quick summary Earth's plates move against each other along the fault suppress
