It's Shaking!


     
 Ladies and Gentlemen,

We all wonder why earth quakes happen, well earth quakes happen when the tectonic plates rub against each other or over lap. That causes the shaking most of the time, the roads wave, or/and the buildings swaying. The roads wave because of the magma under it moving in waves or moving at all.

Did you know that earth quakes go on for a couple of seconds but can cause a lot of damage? The damages an earthquake can cause is fire, damaged houses, roads waving and a lot more.

It is important that we study earthquakes so that we can learn when or how to tell when an earth quake is going to happen mostly so that we can keep every body safe and alert if an earth quake happens. We can only tell how strong an earth quake is by using a Richter scale and the seismograph.

Richter Scale

  1. Pretty strong
  2. 10 times stronger than 1
  3. 100 times stronger than 1
  4. 1,000 times stronger than 1
  5. 10,000 times stronger than 1 
  6. 100,000 times stronger than 1
  7. 1,000,000 times stronger than 1 
  8. 10,000,000 times stronger than 1 
  9. 100,000,000 times stronger than 1 

Looking at the Richter scale each number is 10 times stronger than the one before it.

Earth quakes are most likely to occur were there is a fault line. For example California is right on on a fault line.

 Did you know that earth quakes and Tsunamis are related? Well the only reason a Tsunami happens is an under water earthquake. The under ground earth quakes send big waves that start out small and grows bigger when it gets closer to the shore.

Many questions that people have about volcanoes are, How are volcanoes made?, What are volcanoes?, and How are earthquakes and volcanoes related? First of all a volcano is a mountain from where lava comes from. Volcanoes were also made by lava coming up from the ground and drying into a rock. Soon the rock will grow the more lave comes out and drys.

What determines the way a volcano erupts? Well first of all it depends on how the tectonic plates move, how thick that magma/lava is, and how many gasses are trapped underground.  How do scientists classify volcanoes? 


Glossary 

Fault line
A line in the ground that separates the tectonic plates

Tsunami
An underground earthquake that sends big waves to shore

Richter scale
A scale that can tell us how strong an earth quake is

Seismograph
Telling how big or powerful an earthquake is

Earthquake 
A shaking in the ground of moving tectonic plates creating an earth quake

Magma 
Lava underground that's only called lava above ground

Tectonic Plates
Earth's parts that can rub or overlap

Volcano
A mountain that magma comes up from and explodes or erupts

Lava
Known as magma underground and comes up as lava

Gasses
A scientific name for air or different types of air
