9/11/2001

   What happened on 9/11 was that planes were crashed into the pentagon,the north and south buildings of the world trade center and a field in Pennsylvania.
  There were 19  men at three different airports.They were split up into 4 groups each going to hijack a plane.There was 1 pilot and 4 muscle hijackers in each group.The first group got on their plane and headed off and the second group was not far behind.They took over the the planes a few minutes after take off and turned around to go to New York.
  When they turned around the next plane took off and was soon took over by the hijackers.Then same happened to the next plane.The first plane crashed into the north tower of the twin towers and the second crashed into the south.The third hit the pentagon and the last one was heading for the national monument or the capital building,but the passengers and crew members fought back and took control of the plane.Next they crashed into a field to prevent any more life to be lost.
  9/11 changed the  world by bringing the world closer together than it was.It brought out the best of people and showed true heroes that sacrificed their life for others.It makes everyone more careful with what they do.It also changed America by everyone caring more about  each other.         
  Americans will probably view this as a tragedy,but remember this also as a moment of true heroes and leaders.They will also try to prevent it as much as they can.The families who lost family members will have a family reunion.People will probably treat each other with higher respect,be more generous and be more compassionate.
  The best way to remember 9/11 is to feel sorry for the family who lost family members.I do not think it should be celebrated but remembered.
  The worst thing about 9/11 is that so many people were killed.The best thing that came out of 9/11 is that the world came closer together.Another good thing is that people were helping others as much as they could.

Run here comes the earthquake blog!

    An earthquake is a result of when two plates collide.What happens is that when they collide and start to build pressure.Then it is released and it is in the form of an earthquake.An earthquake releases different types of waves.The waves are called Seismic waves.There are three types of seismic waves.They are called Primary waves,Secondary waves and Surface waves.

   The first wave I will explain are the primary waves.Primary waves are the fastest waves and the first to be detected.You can detect an earthquake by using a seismogram.It tells you where the epicenter.The epicenter of an earthquake is above the focus on the surface.The focus is the center of an earthquake.


                          Here is a picture of a Primary wave.

                         This is what a seismograph looks like

There is also a richter scale.They use it to measure the strength or magnitude of an earthquake.It has numbers from 1 to 10 is the weakest and 9 is the strongest.



                         Here is what a ritcher scale looks like.

                          .

   Now  the Secondary waves.Secondary waves make the ground vibrate.They come a few seconds after the primary waves.They are stronger than the Primary waves,but they are slower.



                        Here is a picture of a Secondary wave.

  Last but not least the Surface waves.They are the slowest waves,but the strongest.They make the ground move in a spinning motion.They can make buildings collapse.They can also be called Love waves


                           Here is a picture of a Surface wave.

                            
                         This is what a surface wave can do.

Continental Drift

    I am going to be blogging about Continental drift.I know what you are saying what is Continental drift.Well I am going to blog about Alfred Wagner's theory of Continental drift and seafloor spreading.Hope you enjoy it.

    

      First Alfred Wagner was a German Scientist.Alfred was born on November 1st 1880.He came up with the Continental drift theory in 1911.He was drafted into the German Army in 1914.

                                            

  Here is a picture of Alfred Wagner.

    Now I will explain what his theory was about.He was talking about how the Earth Was made up of one giant Continent called Pangaea.He had some evidence explaining his theory like plant and animal fossils.He said that people have found four legged creatures in South America when their home is in Africa.


Continental Drift is when the continents move around because of the mantles heat.What happens is that the mantles heat moves the tectonic plates. The tectonic plates move about 1-4 inches a year.

                                  Here is a picture of Pangaea.

    Seafloor spreading is something that happens at the oceans crust.Seafloor spreading is when two plates move away from each other because of the mantles heat.Like how South America keeps moving farther away from Africa.

                       Here is a picture of Continental drift.

 

  

Here is a video about Continental drift

Here is a video of ice age 4 Continental drift.

Earth's structure

    Today's blog is about Earth's structure and the layers of the Earth.I blog about how thick each layer of the Earth is and what they do.


First is the top layer the crust.The crust is about 35 kilometers thick on land.The crust is 15 kilometers thick at the bottom of the ocean.The crust is the layer we live on.It is cool hard rock so we can live on it.It contains tectonic plates that move the continents.
 

The next layer is the Mantle.The mantle is the thickest layer of the Earth.The mantle is about 2850 kilometers thick.The mantle is made up of melted rock.It is about 4000 degrees in the mantle.


Next is the outer core.The outer core is made up of iron and nickle.The outer core is the only layer of the Earth that is all liquid.It is about 2,200 kilometers thick.


Last is the inner core.The inner core is a ball of solid iron.It is compressed together so hard that it never melts even though it is as hot as the surface of the sun.

There is a movie called the core and I think it is cool.There is a link down at the bottom and some other stuff.

PLATE TECTONICS!

    I am going to blog about plate tectonics today.This blog post will include the following: how the earth was formed,what Pangaea is,what are tectonic plates and what are six  plates.
    First things first the earth was once called Pangaea.Pangaea was made up as one continent.The continents were combined.Over time Pangaea started to break apart.North America was the first continent to break.Then came South America,Eurasia,India, and Africa.The reason they broke apart was because volcanoes.This happens because the plates move around in the earths crust and go down to the mantle.They have dead krill and other stuff from the seafloor on them.When they go to the mantle the heat burns them and produces carbon dioxide.When a volcanoe erupts the carbon dioxide is realeased.The seven main plates are the eurassian plate,indian plate,north american plate,south american plate,pacific plate,oceanic

Back to school

     

 Hey I am back at school and doing blogs again.I am going to blog about what I did this summer,what my goals are this year and my weaknesses from last year.

 I did not a lot of things over the summer.The first thing I did this summer is go on a week long cruise on the carnival freedom.It was so much fun and I was sad to come home.It docked in Jamaica,Grand Cayman and the Florida Keys.

                                         Here is a picture of the carnival Freedom

  They have a big water slide on the lido deck.They also have a 24 hour pizza bar and ice cream machine.If you do not want pizza or ice cream you can have a salad.They also show a movie every night on yhe lido deck.They have mini golf and a bascetball and court on the sky deck.

      

I went to a few summer camps and visited my grand parents and I stayed at home a lot,so any ways lets move on.

  My goals this year are to get more comments on my blogs.I want to be more creative and have better blog titles.

My weaknesses last  year was that it was my first year and I did not have any experience.This year I know a little bit more and have better topics to blog about.

Amphibians:I

   I know what your saying that you don't need to learn about this because you learned about frogs already,well you do because there are more than just frogs in the amphibian group and I am going to blog about them.

  The first thing I am going to blog about is the characteristics of AMPHIBIAN'S!First amphibian means double life that means in their life they live in water and on land.Amphibians have smooth slimy skin and must keep it moist or they will suffocate.There are three groups of amphibians frogs and toads,newts and salamanders and Sicilian.

  The frog I am going to blog about is the leaf frog.The leaf frog blends in with the fallen leaves in autumn.It is very small and relies on it's camouflage to survive an not be eaten.

The next thing I am going to do is blog about is the green toad.Personally I think it is ugly.The green toad  can be found in praries next to rocks.

The next one is the hammerhead salamander.It has a head like a hammer you could of guessed.It has smooth moist skin like other amphibians.This is my favorite amphibian.
