Acid Rain Article

1.) List a few of the gases which lead to acid rain. Sulfur dioxide and nitrogen oxide

2.) What is the source of much of the acid rain producing gases in Pennsylvania? Coal that is being burned in power plants, cars, and agricultural sector.

3.) Briefly explain how acid rain forms. It forms when sulfur dioxide and nitrogen dioxide in the atmosphere combine with water to form sulfuric acid and nitric acid. And then mix with rainwater, fall to the earth as acid rain.

Mississippi Flooding

       The Mississippi River continues to rush downstream, The flood-level water is heading directly for some of the Louisanna communities still recovering from last year's oil spill and possibly forcing hundreds of thousands of people to evacuate. It was has reached 47.85 feet, Officials said the river is expected to crest at a record level there on May 21. The river will continue to press against Memphis levees for at least the next few days. Some homes have been inundated and are likely uninhabitable.
       Everyone that lives around or close to the river should evacuate there houses, take what they need before there house is destroyed. It could kill them if they stay the Rivers only getting larger and flooding more. What scientist are predicting doesn't sound to good. So I think people should better be safe then sorry.

Protecting villagers from deadly mudslides

• What are some natural factors causing mudslides in Guatemala?
• frequent earthquakes, hurricanes and heavy rains oversaturate Guatemala's mountainous terrain and muddy the soil.
• What are some human factors causing mudslides in Guatemala?
•  Trees are cut for firewood and to make room for the crops, and without realizing it ... they've taken away their protection. Where it used to be rainforest becomes an open space for the mud to come right on through
• What is being done to help reduce mudslides and mudslide damage?
• that many local Guatemalan tree varieties could be strategically replanted to provide fruit, fertilizer, coffee, food and medicinal herbs where resources were failing or nonexistent.

temperture trend

• The horizontal scale of my graph is 1850-2000.  It shows eight years.
• The vertical axis is showing temperature. The units are in celcius. The total range is -0.6 to 0.6
• They don't say where the data came from.

global warming

• 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.
• I think the global average temperature is 50 because everywhere has a different climate.

• 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 it's like 2%, and yes this is alot.
• 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.
• the warmest is probably like 100 and the coldest is probably -10 or something.
• 4 - Are you concerned about "global warming?"  Why or why not?
• i dont really care!

question 4 on page 266

The amount of rainfall affects weather a soil is a grassland or a forest soil. They both need rain in the region there in, but grassland soils needs less rain because it needs to support grass but not heavy tree growth. Forest soils need enough rain to support heavy tree growth though, so it needs more.
