1. Astronomers measure the light coming to Earth from a distant star. From this data they can derives several types of spectra. Explain how the astronomers might use one of these spectra to determine the temperature of the star's photosphere.

2. Describe the difference between emission-line spectra an absorption-line spectra. Using your knowledge of the structure of atom, describe how the interaction of light and atoms produce each type of spectrum.

3. Describe the best current model of the origin of the solar system.


Thanks!!!

I'm fascinated by the giant crocs and want to see one in person, but the only zoos i can find that have them in captivity are a little too far away (I'm in NY. The only place i found was in Australia and i can't afford that trip.) Thanks.

Scenario: a frozen lake in, say, Northern Onario. You gather wood etc. and light a "bonfire." Would the heat of the fire burn through the ice? Would the ashes of the fire create a barrier between the ice and the heat?
We are having a discussion about this and, apart from actually trying this out, wonder if anyone knows?
