Iceland Volcanic Eruption

Summary:
Concerns about major air travel disruption are mounting after Iceland’s most powerful volcanic eruption in over 50 years threw a huge cloud of ash 12 miles into the air on the weekend of May 23,a year after ash from the Eyjafjallajökull volcanic eruption reached Europe, closing much of its airspace. Initially, European airspace was not expected to be affected but in at least two hours Eurocontrol, Europe’s air safety organization, issued a statement confirming that “some ash cloud may reach parts of northern Europe in the next 48 hours.”

I was quite shocked to hear that the same volcano erupted for a second time. I'm glad that they shut down air travel in time so that there were no accidents. They should start looking into why the volcano keeps erupting. They could maybe try and find answers on how we can be prepared for another eruption. 

Acid Rain

1.Acid rain is caused by sulfur dioxide and nitrogen oxides produced when fuels burn.

2.The pollutants that cause acid rain come from local sources and sources located in the Midwest and affect a wide region up into New England.

3. Sulfur dioxide production can have a major impact on acid rain in Pennsylvania and other regions of the Northeast.

Science Questions

• 1 - What do you think the global average temperature is?  This means the average for everywhere on Earth, day and night, for an entire year.  Explain why you answered what you did. 48 degrees, I don't know why I put this I just thought it was a good guess.
• 2 - People are often talking about "global warming."  How much do you think the average global temperature has increased in the past 100 years?  Do you think that this is a lot? No not alot, I say at least 1 degree because it takes a long time for the globe to change its overall temperature.
• 3 - What do you think is the hottest the Earth has ever been? (since there has been an atmosphere?)  How about the coldest the Earth has ever been?  Explain why you answered what you did. I think the hottest temperature would have to be at least 600 degrees and the coldest would have to be -135 degrees I picked these because the earth was once molten and I think the coldest would be this cold because the earth has gone through many ice ages.
• 4 - Are you concerned about "global warming?"  Why or why not? Well I'm about half and half because I think the concept of global warming is exaggerated a little bit, but I do think that we need to clean our act up or global warming could be a very serious problem one day.

Question 4 pg. 266

The amount of rainfall in the grasslands is enough to create thick grass, but not enough to create trees or thick woodland areas. The amount of rainfall in the forest regions are enough to sustain thick woodland areas. It depends on the area of climate and weather you are in a warm one or a cold one, like say it was  desert climate, this wouldn't be a place you would see substantial, or hardly any, rainfall. Opposed to if you were in a this luscious forest you would see a lot more rain fall.  

Mass Movement: Slump

Slumps take place as a movement of earth or rock material, often as several independent units, creating a number of step-like "terracettes." Undercutting of slopes by stream erosion, waves, and road building are common causes of slumping.

Here is an example of a slump

PUNISHMENT

The gulf oil spill was one to cause extensive damage to marine and wildlife habitats as well as the Gulf's fishing and tourism industries. It is estimated that over 53,000 barrels of oil were being spilled every day. Although the flow of oil has stop, it still is having affects on the wildlife and the people living in that area. The total amount of Louisiana shoreline impacted by oil grew from 287 in July to 320 miles in late November of 2010. I have read that the U.S. government has blamed the BP as the responsible party and officials have committed to holding the company accountable for all cleanup costs and other damage. If this is the case then i vote yes for these people to pay for all damages to the communities and the marine life. I also think that the families of the workers who died should get something for what they've gone through, even a letter of apology would be good. All I want is that the people who are responsible for this should be brought to justice.

Coal

Coal is made up of Carbon, Sulfur, Hydrogen, Oxygen, Nitrogen. Coal starts as plant layers at the bottom of the ocean over time it changes into a solid material. Coal is extracted from mines and deep pits.
