Current Event

The main point of this article is to inform everyone about the damage that has been cause because of a tornado.  Many people have never experienced a tornado so they don't know what its like or what they can do. The tornado in Joplin killed several people in injured many. It also destroyed many buildings including a hospital which is very important at a time like this when there are people injured who need help. It also caused many people to be without electricity or even homes. Joplin was right in the path of the tornado.

I think that tornado's are a horrible thing. It can change many people lives. People can lose family, friends, houses and many other important things. Tornados hurt and kill many innocent people. It's sad to see how many people die in one place at one all because of a tornado. It must be hard to live somewhere that you have to worry about that type of stuff happening to you.

Acid Rain

1. Acid rain is caused by sulfur dioxide and nitrogen oxides.

2. There is so much acid rain in Pennsylvania they burn a lot of high sulfur coal in power plants.

3. Power production is  a big part of how acid rain forms. Another big mark it automobiles. Lightening and biological processes make nitrogen naturally.

Mudslide Article

• Some natural factors causing mudslides in Guatemala are earthquakes, hurricanes and heavy rains which makes the earth less stable. Guatemala also has muddy soil.
• 
  
• Some human factors causing mudslides in Guatemala are that they cut down the trees so that they have fields for crops, they also use the trees for fire wood. The trees hold down the earth and protect the people from mudslides.
• 
  
• What is being done to help reduce mudslides and mudslide damage?
• They are going to try to plant trees. They trees will also provide food, shade, and fertilizer. Pine trees have roots that are 6 meters underneath the earths surface so a mudslide wouldn't rip them out.

Global Temperatures

The horizontal axis is showing how many years. It ranges from the year 1860 to 2000.

The vertical axis shows the temperature. It increases by 2 degrees C. The graph ranges from -.6 to .6 degrees.

The picture doesn't tell where they got the data from.

The more rainfall there is the soil is better. With more water the soil will be more moist which is better for plants to grow in.  The rain will help keep the topsoil fertile.

•  1. I don't know what the global temperature is, but if I had to make a guess i would say it would be around 60 degrees. I think this because it is the average around the whole earth.
• 
  
• 2. I think that the temperate has increased a lot over the past 100 years. Probably by around 2 degrees  or something around there but that it still a lot for only 100 years.

3. The hottest the earth has ever been is when it was being formed. The lowest it has been was probably a long time ago, over thousands of years ago.

4. I am concerned about global warming because it is ruining the planet. Also it is killing many things like animals. It is also making the ocean hotter which is killing polar bears and melting the ice caps. Also when the ice caps melt it will cover some of the earth and will raise the sea levels.

Mass Movement/ Slumps

   Slumps are made by a backward rotation of the earth material as it moves along a curved failure plane resulting in a reverse slope. 

The Gulf Oil Spill

The oil spill that happened in the Gulf was a very bad thing. I think that the people who made the machine and came up with that idea should be the ones to take blame for what happened. It isn't entirely their fault but it was mainly there fault and there were things they could have done to prevent this. They should have taken more time to plan this so that they could thing about the consequences that could happen. If they had done this then the oil spill would most likely not have happened. BP oil are the people who constructed the drilling to happen so it is mainly their fault because they could have done more research to make sure that this procedure was safe. Although they are not the only people who are at fault for this. We as people have to take some of the blame because we demand oil. People use it in everyday life and we needed to find ways to get the oil. I don't think that anyone should be punished but we should learn from this and be careful and more cautious for the next time we need to drill oil.

Dante's Peak

Accurate:
-Affects of a volcano
-Evidence that a volcano is going to happen
-When the volcano erupted, the pyroclastic flow is really fast and is very hard to escape 
-When there is a lot of sulfur dioxside in the air the volcano has magma in the holding chamber

Inaccurate:
-It would be unlikely that people would be able to run away from a volcano
-You couldn't drive through hot lava
-Dante's Peak is not real
-Its not possible to drive out of a pyroclastic flow
-Because the lava is so hot they could not just like walk over it.

Coal

Coal is mostly made of carbon and hydrogen. It is formed when peat is altered physically and chemically which is called coalification. This is when peat changed as a result of decaying bacteria, compaction, heat and time.

Fossil homework 9/21

The second picture is a mammoth. It was preserved by being frozen or being barred in the mud or sand.  All of the remains were copied and molded like casts giving the rock its texture and shape. They replaced the remains withs molds.

The first picture is the fossil from its original remains from when it was alive. We got the fossil from it being preserved and frozen in the ground.

Relative dating homework 9/17

3, 2, 5, 4, 6, 1

I think its in this order because number 3 and number 2 intruded the other layers. Number 3 is the oldest because it goes through all of the layers and number 2 just goes through a few layers. The next youngest is number 5 because it is the next one at the bottom. The next layer is number 4, 6, and then 1.
