Word Poblems

[jesusfreak210]

I was given these word problems and I thought I'd let some others take a crack at it. Here we go:
1. In a certain aera of the country, many of the fish in a local lake have died. In addition, soils were found to be highly acidic, and nearby trees were losing their leaves. What kind of pollution may have caused these problems? What is the source of this pollution?

2. In a drive across the desert with your family, you see a distant sand dune that appears to be floating on air. How can you explain what you see?

3. In what ways would a knowledge of the global wind belts have helped a sixteenthe-century explorer between Spain and the northern part of South America?

If you can answer any of these, start you answer with the number of the problem followed by your answer. Happy answering!

Howdy, you Jesusfreak, you.

Sounds like you want to con us into doin' your homework.

No dice. Sorry, we don't work that way.

But in the meantime, you can mull over this little problem:

If the same dog runs down to the same beach to take a crap on the same dune every day for a month, how many ships would it see?

[Racoon]

1. Pesticides ; Humans

2. Someone had taken magic mushrooms

3. Maybe they wouldn't have ended up killing so many Injun's

3. is rather a cool question. I wonder how many are aware of the trade winds.

Depends on the size of the dog. Can it see above the dune?

1) In a certain aera of the country, many of the fish in a local lake have died. In addition, soils were found to be highly acidic, and nearby trees were losing their leaves. What kind of pollution may have caused these problems? What is the source of this pollution?
Maybe they are not related... and there's just a big bear eating all the fish eggs and stepping on the live fish and scratching his back on the trees causing them to lose their leaves. The soil may have nothing to do with it all...


2) In a drive across the desert with your family, you see a distant sand dune that appears to be floating on air. How can you explain what you see?
Gradient Index Optics, aka mirage. Or, you could go about it in terms of visual perception and interpretation, discussing the occipital lobe and pre-frontal gap filling.

3) In what ways would a knowledge of the global wind belts have helped a sixteenthe-century explorer between Spain and the northern part of South America?
Maybe fewer slaves would have died rowing because the sails were more productive... or, perhaps the girl this explorer was courting wouldn't have been so repulsed by his awful unshowered scent, as the winds carried it away from her olfatory senses.

1. Acid rain
2. Mirage - refraction of light off a glancing angle between the hot and cooler air
3. He could have used them to move around faster..?
