Earthquakes, Volcanoes, Tsunamis, Oh my!

Dear Audience,

       Earthquakes

         Earthquakes are very dangerous. Earthquakes are caused by Tectonic plates under the land. Tectonic plates are large rocks under the land that is what the land sits on. When Tectonic plates slide, the pressure causes the plates to release the pressure. The plates break, causing the earth to shake, shift, or buckle.

         Earthquakes change the surface of the Earth in many ways. It can separate the ground, it can create Mountains, and it can create Volcanoes. It can also push the ground together. Mountains that already exist rise up and get bigger.  

        People study earthquakes for many reasons. They study it so they can figure out how much the difference between the earthquakes and how much stronger they are getting. They also study it to figure out how it is happening. It happens because tectonic plates overlap or push together.

        The damage caused by earthquakes are very dangerous. It causes building to catch fire because of the wires for electricity in the building break. It also causes tsunamis. Scientists use a seismograph and a Richter Scale to measure an earth quake. There can be size earthquakes like a 1.0, 2.0, 3.0 and so on. The bigger the number the more damage there is.

        It is important that people learn more about Earthquakes for many reasons. People study it so they know what to expect. They are designing building that can withstand an Earthquakes.

       Earthquakes most likely occur in places where tectonic plates meet. Tectonic plates crash or slide into each other causing the Earthquakes. California is one place where two plates meet. It is called The San Andreas Fault. Another place is The Atotsugawa Fault in Japan.

       Tsunamis are related to Earthquakes because Earthquakes cause the Tsunami. Tsunamis Are huge waves that form in the ocean when the Earthquake occurs. The wave grows bigger and bigger the closer it comes to the land. When the wave hits land it wipes buildings of the foundation.

        Earthquakes and Tsunamis are very dangerous. If you live near a place where one has occurred, then have something ready with food and water and always be ready to go to high land( Not a building).

Volcanoes

         Volcanoes are very dangerous. Volcanoes are openings in the Earth's crust where magma and gasses rise. The eruption of the volcano depends on how the tectonic plates interact, How thick the magma is, and the amount of gas trapped underground. Some eruptions are explosive and some are gentle.

Nervous System

 
Dear Audience,                                                                                                                                  The nervous system is important to you because it helps you survive. The nervous system is a system that carries information through your body. The information might be telling your arm to move or grab something, it can tell you to take your hand away when you touch the hot things, it can grab something quickly, and it can move your body parts very quickly. It moves muscles and receives information from outside of the body. The brain uses your five senses to receive information from outside the body. Your senses are attached to your nervous system. The eyes see things, the nose smells things, the mouth tastes things, and the hands feel things. The nervous system moves your muscles by sending messages to the muscle telling them to contract or relax. Certain parts of the body are completely cared for by your Nervous System. For example, the brain tells your leg to step around the object in your way. The brain works with involuntary muscles by sending messages to your organs telling them to keep working without you telling them to. For example it tells you to breathe, it tells you to walk, and it tells your heart to beat. Your body works every second. If your body didn't work when you slept, you would never wake up because you would of stopped breathing and die in your sleep. The brain is the main part of the nervous system. The brain controls thoughts, movement, and decisions. The brain is attached to your spinal cord and all your nerve cells. The cells make connections as you learn. The nervous system is very important
to your body.

Getting To Know Dirt

I think that our sample of dirt (skittles and Chex mix) is a mixture because you can separate it by hand. It has three green skittles, four orange skittles, three purple skittles, three red skittles, and a lot of Chex mix. I think the soil is unhealthy because the skittles are poison and there are 13 skittles. And even one skittle contaminates the soil.
