question 4 page 266

The amount of rainfall affects it because the more rainfall the better kept the soil is, the less rain fall the more desert and sand there is. Also up in the northeast there is more rain and snow which is more water and rain to feed the soil and keep it fresh. But in the south-southwest there is only rain to keep the soil fresh, and with the amount of sun it gets being closer to the equator than the north it keeps the south dryer than the north.

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.
about 55 degrees. i looked it up.

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 that the average global temperature has increased by at least by 10 degrees Fahrenheit in the last 100 years

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.
it has been 5000 degrees when meteors crashed into it

4 - Are you concerned about "global warming?"  Why or why not?
no. because we live on the coast

I think that humans should sight their source on renewable fuels. With renewable fuels it won't matter if we have or don't have fossil fuels because of renewable energy. A 71% reduction in fossil fuel consumption would lead to a reduction of just under a quarter (24%) of man made global warming. I think what wind energy, energy given off currants and sun. Sooner or later the earth is going to run out of fossil fuels for us to use and we will be sorry. All people are dependent on fossil fuels for transportation, heating, cooling, packaging materials and a lot of other things in life burning fossil fuel releases greenhouse gases which cause global warming, also extraction of these fuels alter the environment. Burning fossil fuels is one of many contributors to climate change.

Coal

Coal is a combustible black rock composed mostly of carbon and hydrocarbons. It is the most abundant fossil fuel produced in the United States. Coal is 50% carbon. About 95% of the coal used in the United States is used for electricity. The rest of the coal is used as a basic energy source. The major uses of coal are for industry and electric power.

Dante's Peak

1. The scientific instruments used, like seismographs.
2. They pyroclastic flow and magma
3. lahars

1. When the truck was in the pyroclastic flow the truck would of melted or at least the tires would have exploded.
2. The lake turned to acid in a very short period of time.
3. The truck would have caved in, in the mine shaft
