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

Brain Cells and Nerves

Welcome Friends,

The nervous system is important because if we didn't have the nervous system we wouldn't be able to see, hear, feel, smell, or even taste. Our brains can help us do a lot of things for example: see. Without some parts of our nervous system or the nervous system at all we won't be able to see or even move our whole entire body! Our nervous system is basically electricity going through out our bodies and sends a key that's telling our body to move the hand or to move your feet. The messages that goes to your body is the electricity going through your spinal cord and to the body parts.

 Do you ever wonder why you move so quick when you touch something hot or when somebody scares you? Well that's because your brain is prepared for what ever is going to happen. Your brain is like electricity just like the way you turn a light on, it turns on without having to wait or anything.

 Have you ever wondered if you just received information in the inside of your body? Well you receive things from outside of your body with your senses. For example, when you see something bad happening or good happening that sends a message to the brain from inside but received from the outside, which tells your brain to relax or to freak out. It is just the same with hearing when you hear a loud noise you jump cause your brain received that maybe something bad is happening. And when you hear a small noise your brain kind of relaxes which means that you relax.

Another question you may ask is how do my muscles work with my nervous system? The nervous system can send a message to your muscles to either relax or to strengthen. One way the your nerves can tell your muscles to relax is when you have a stressful day or tiring day like at work. The time your nerves can tell you to work up is when you are working or running.

 I bet you also wonder how come your heart beats with out you telling it too? Well that's cause your brain is is telling it to beat with out you even telling your brain to tell your heart to beat, or your lungs to inhale air. Did you know that our body is working even when we  are asleep? That is because your brain like everyone Else's,it's involuntary. Involuntary means works on its own. Your hand moves up and down cause your brain is telling it to. But your heart beats by itself. Another example of involuntary is you brain; you don't need to tell your brain to work it just works. Now how does our brain work with the involuntary muscles? Occasionally our brain should know what we need day and night so, our brain will always tell the muscles that we need them so they will keep working. Think of all the things we would have to do if we didn't have involuntary muscles. Make our heart beat , tell our lungs to breath in air, and even noticing quick when somethings hot. So lets take a moment and say, "Thank you" to our brains.
