Transcript of Earthquakes
an Earthquake? Earthquake example: The ground vibrates and it shakes
until it will collapse. The ground cracks and it gets destroyed What do we have to do? go under furniture
Boil water So that when the roof falls down, you have something to protect your head from getting hurt/injured... Why do we have to go under furniture? Don't move?-why? because the ground will shake and you might fall down Boil water?-WHY??!! To kill germs!! Why do earthquakes occur? Earthquakes are usually caused when rock underground suddenly breaks along a fault.
When two blocks of rock or two plates are rubbing against each other, they stick a little. Well... if I were you, I would use the safety combo, which is:
HOLD! Now I will ask you...
what will you do if there
was an earthquake? ? Thank you for watching this! BROKEN GROUND: E
E why? Drop
This position protects you from falling but allows you to still move if necessary
So there is something stable/strong to protect your head. (go under your desk)
So you can hold on something sturdy until the shaking stops. It occurs whenever the tectonic plates move together, they are actually being pushed against each other. They either collide or move against each other...
Australia, New Zealand and India used to be joint together but because of the movement of the tectonic plate, they were separated once again.
Tectonic plates move very very slow. Earthquake facts More Facts about Earthquakes: There are Big Earthquakes and modest ones. Big ones mean that it is strong and small ones are weak.
