List 4 components of the universe we have discussed in class.
What is galaxies, stars, comets, meteors, asteroids, planets, moons, nebulas, black holes, etc.
100
What is our sun so big and bright to us?
What is because it is the closest star to us.
100
How is the shape of a radio wave compared to a gamma wave?
What is Radio wavelengths are much longer than gamma wavelengths.
100
What is an Astronomical Unit?
What is the distance between the sun and the earth.
100
What is the big bang theory?
What is the theory of the origins of the universe.
200
What is a galaxy?
What is a cluster of millions of stars and other space objects.
200
What is a Nebula?
What is a grouping of gas and dust in which stars are born out of
200
Which do most things have in the universe, red shift or blue shift?
What is Red Shift
200
What is a light year and how do scientist use it.
What is how far light travels in a year and scientist use it to measure space.
200
What is one piece of evidence that supports the Big Bang theory.
What is Red shift tells us the universe is still expanding, remnants of the original energy have been found, and that there are large amounts of hydrogen and helium (the simplest elements to make).
300
What are the 3 types of galaxies?
What is irregular, spiral, and elliptical.
300
What type of star is our sun and where does it fall on the HR diagram? (be specific)
What is a main sequence yellow star and it falls in the middle of the main sequence stars (medium temperature and luminosity).
300
What does the blue shift tell us about a space object?
What is it is moving closer to us.
300
What is a black hole?
What is a star at the end of its life cycle with a tremendous amount of mass and gravity in which light can't even escape.
300
Is the big bang theory the only plausible theory and why?
What is no, it is just the most popular one.
400
Where are we located in our galaxy (the milky way)?
What is on the outer edge.
400
What does the HR diagram tell us about stars?
What is star's luminosity and temperature and that the average star's temperature increases as luminosity increases.
400
Is something has a red shift, what does that tell us about that object?
What is it is moving away from us.
400
What happens when a comet gets close to the sun?
What is its ice melts and it forms a tail.
400
What does the Red Shift tell us about the universe?
What is that the universe is expanding.
500
How many stars exist within our solar system?
What is one, the sun.
500
What is the single most determiner of a stars life cycle that will determine what a star will become?
What is the density of a star.
500
Explain how scientist can tell is something has a red shift or blue shift.
What is something has a red shift if its light waves are getting bigger and something had a blue shift if its light waves are getting smaller.
500
What is a meteor?
What is a rock in space that enters the earths atmosphere creating what looks like a "shooting star".
500
What happened during the big bang?
What is a singularity expanded very fast and the temperature cooled.
