Please give me as much information you know on Astronomy/Cosmology.
NO COPY DOWN THING DIRECTLY FROM WIKIPEDIA OR ANY ENCYCLOPEDIA!
(i tried them already... i still dont get it!!! so... please explain them to me BY YOURSELF!!!)
also...
please answer the questions I have below...
thanks
=================================================
1. What does the color of a star tells us?
2. How do we determine which stars are hotter than others? (Be specific please)
3. Why is the actual motion of stars so difficult to see from Earth?
4. What relationship does the H-R Diagram give us?
5. What is nuclear fission? Nuclear fusion? How are they different?
6. Define a white dwarf
7. Define pulsar
8. Define supernova
9. What is the difference between apparent magnitude and absolute magnitude?
10. How many kilometers is a light year?
11. What are galaxies? Name theh types of galaxies and how they are different.
12. Which galaxy is Earth located within?
13. Why do we study distant galaxies?
14. What happened during a Big Bang? And... what is the radiation called?
15. Define astronomy. Define cosmology. Are they differrent?
16. How are galaxies classified?
17. Define nebula.
18. What are main-sequence stars and where are they located on the H-R Diagram?
19. What do scientists observe to find out what early galaxies looked like?
20/ Define parallaz.
21. Discuss the absorption spectrum. What do the black lines indicate?
22. Define quasar.
23. How long ago do scientists now believe the Big Bang occurred?
24. What planets in our Solar System are considered inner planets? Outed planets?
25. How are the inner and outer planets different?
26. What is the difference between a meteoroid, meteorite, comet, and asteroid?
27. Define gas giant. Name the gas giants in our solar system.
28. Define astronomical unit (AU).
29. Define solar nebula.
I did!
but the point is...
I'm still an ESL (English Second Language) student... my English skill still isn't that good...
I did do the questions by myself...
but i just want to check if I got them right or not since the test is on Friday... and the quarter IS ending of Friday... so I don't want my grade to lower because of that...
by the way... to cosom: I'm in 8th grade... i dont think it's anything like Astronomy 101
