Earth Sciences & Geology - February 2007

I have a true or false question about minerals.

For the majority of minerals, the streak color obtained when the mineral is scratched against a porcelain plate is the sama as their apparent color.
is it true or false.

thanks

There is no proof that mans activities on earth cause global warming. This planet has heated up and cooled down many many times in the past. The global temp has went up .06 degrees in the past 10 years. One huge volcano can drop the temp by 2 or 3 degrees world wide (discovery channel). There is evidence of the ice caps melting on mars ... do martians drive SUV's. How can policy be made on such inconclusive studies? Why do schools teach our kids global warming and not teach real science?

In a certain website (which I cannot recall) it was stated that the "Sea of Galilee" will dry out in approximately 50 years time.This site I recall also monitors the water level periodically.Is this factually correct.

1)It is believed but controversial that the water is now sometimes H1.5O.
2) If massive protons are made up of quarks and gluons with zero mass, how would you argue "mass is conserved"
3) "for every action there is an equal and opposite reaction". Sure there is. Tell that to the magnetic force between two charged particles.

What the harry is going on. Is there no rest for the scientist
