The last time volcano Grimsvotn erupted under the Vatnajokull glacier was in 2004. The plumes coming from the volcano disturbed much travel in Northern Europe last spring. Officials say that it's unlikely for the eruption to cause problems like last year, but flight bans have been set in the area. The plume of white smoke that came from Grimsvotn was about 15 km in the air. The eruptions aren't predicted to be like 2010 although they are waiting to see how the ash will act.
Even though it's still considered unlikely for there to be a major eruption anytime soon, I still think it's a good idea that air travel has been temporarily shut down just in case anything serious does happen.

Acid Rain
1. A few gases that lead to acid rain:
Sulfur dioxide and nitrogen oxides.
2. What is the source of the most rain producing gases in Pennsylvania?
Power prodcution, automobiles, and agriculture.
3. Briefly explain how acid rain forms:
Sulfur dioxide and nitrogen oxides combine in the atmosphere with water from sulfiric and nitric acid. They then mix with water an fall to Earth as acid rain.

Mudslides
What are some natural forces causing mudslides in Guatemala?
Frequent earthquakes, hurricanes, and heavy rains that turn the soil into mud, causing the soil to loosen up.
What are some human factors causing mudslides in Guatemala?
The absence of trees has contributed a lot. Villagers cut trees down to make room for their crops, and use for firewood. It leaves room for the mud to slide right in.
What is being done to help reduce mudslides and mudslide damage?
They're going to plant more trees, especially pine trees on the mountainsides. It will soak up the rain, and the sliding mud will not pull up the trees' roots.

Global Temperature Graph
What is the horizontal scale of your graph? It goes from 1860 to 2000 in incriments of 20 years.
What is the vertical axis showing? The temperature in degrees C.
What are the units? It goes up by .2 degrees C.
What is the total range shown? The increasing temperature from -.6 to .6 degrees C.
Can you tell from the host's page where the data came from? I couldn't tell, result was "Page not Found." But it looks very exact, so I'm guessing from some educational or governmental site.

Global Warming
1. I think the average temperature around the globe is 70 degrees Fahrenheit. I think this because a lot of places are really warm, and many have that as the average year round.
2. Global Warming has probably increased by about 15 degrees Fahrenheit. It is a lot for polar animals, who need it to be cold all real round.
3. I think that the hottest the earth has ever been was 125 degrees Fahrenheit. The coldest was probably -90 degrees Fahrenheit. I just guessed it because it seems a reasonable range.
4. Yes, I am very concerned about global warming. Ice caps have been melting at an alarming rate, and many polar animals like polar bears are close to extinction because of warming temperatures.

Question 4
More rain makes soil more fertile for growing crops, and trees able to grow. Where it is colder, there isn't rain so therefore vegetation cannot grow.
