This data came from the NOAA (Earth System Research Laboratory). It tells what the temp. is in the atmosphere and it rises about 1% every year. The units are ppm and the horizontal axis goes from 1857 to 2007, (50 years). The vertical axis goes up by 10 from 300 to 380, (80). Something like that...

Four 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.

Maybe around 30-40 degrees. I think that because in a lot of places like Maine it is somewhat cold all year round and sometimes it's really warm, so kind of in between warm and cold.

• 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?

 I think maybe the temperature has gone up about maybe around 5% something like that. Mostly because winter is not lasting as long and its been getting warmer outside even in winter.

• 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.

 Maybe the hottest would be like 120 degrees around there, and the coldest would be something like -200 degrees. I think that because we have had heat waves and the ice age.

• 4 - Are you concerned about "global warming?"  Why or why not?

Yes because there are so many green house gasses from all the cars and buisnesses and such that everything is getting so polluted and it's getting warmer all year round.

Qustion 4...

I think that places such as the desert get little rain because there wasn't much water there to begin with and after a while there was no more moisture around because it kept evaporating from the heat and the clouds disapeared from the heat. The rain depends on how much water is there to begin with because when the water on the ground evaporates then it goes into the air and into the clouds, and when the clouds fill up with too much water it begins to rain. The more water in the area, the more it rains.

Mass Movement-Avalanches...

Snow Avalanche: a mass of snow, ice, and rocks falling rapidly down a mountainside.

What I think...

The people that are responsible for the oil spill and most of the other oil spills that accord would be the company itself, and the people working there. The people working there are responsible because they didn't pay attention to what they were doing and didn't do anything about it. Also the company is responsible because the tube/machine was faulty and they didn't care about it being damaged. Also the company that actually built the tube didn't do what they were supposed to do and the oil company probably knew that it didn't work and bought it anyway so that is why they should be fined and then be sent to prison for at least five years because now tons of gallons of oil is being spilled in the ocean and killing tons and tons of animals. To clean it up, they should get everyone from the company to spend all the time they can and clean every gallon of oil that had spilled. That is what I think of the situation with the oil spill.

How Coal is formed...

Coal is a fossil fuel because coal is formed from the remains of dead things and many years of vegetation. The element that gives coal most of his energy is carbon. After many years sedimentary rock would form together with it to create its rocky form, and that is how coal is created. Now the energy that it gives off after being burned is called coal gas and can be made from burning it.

Is Possible...
Lahar, lava, and pyroclastic material flowing down the side of a volcano.

Gas/chemicals under water can turn the water into acid, (or make it more acidic)

An earthquake while the volcano is erupting.



Is Not Possible...
A full out blast from a composite volcano on only one blow.

Every building and structure falling apart right off.

When driving through lava, it would have melted it quicker and melted the wheels.
