Nucleosynthesis & Celestial Objects
Why can’t stars fuse elements heavier than iron?
Fusing iron does not produce any energy, therefore the star has no energy left to fuse any further.
What is the relationship between wavelength and energy?
As wavelength increases, energy decreases.
What landscape region is Lake Ontario located in?
Erie Ontario / Central Lowland
Name the 3 types of plate boundaries.
Divergent
Convergent
Transform
Why can't carbon-14 be used to date a rock?
Carbon-14 can only be used for organic materials.
How does increasing eccentricity change the shape of a planet’s orbit, and how can this affect the planet’s seasons?
Low eccentricity = perfect circular orbit.
High eccentricity = oval shaped orbit.
Higher eccentricity results in more extreme unbalanced seasons.
When hydrogen is heated, what color does it produce?
Blue
Name the latitude and longitude for Binghamton?
42 N , 76 W
What happens when two crusts with the same density collides?
What is the total time required for Uranium-238 to undergo two half-lives?
9 Billion years
How does CMB support the Big Bang Theory?
CMB is redshifted, meaning our universe is expanding. Energy from the Big Bang caused the expansion of the universe.
What is the wavelength range for red light? (include units)
630 nm - 700 nm
What resources are relocated in Jamestown, New York?
Oil , Gas
What type of plate boundary is between the Pacific Plate and Philippine Plate?
Convergent Plate Boundary
How old is the Earth and which radioactive isotope was used to figure this out?
Earth is 4.6 billion years old, found using Uranium 238
Which stage of nuclear fusion takes the longest amount of time? Why?
Hydrogen. Every star starts out with a large amount of hydrogen, which requires lots of time to fuse.
What type of star is the Sun?
Main sequence star
At which location are the youngest bedrocks found?
Long Island
How are crusts formed? ( 3 steps )
1. Plates diverge
2. Magma rises
3. Magma cools off and forms crust
Given a sample with 25 grams of Potassium-40 and 75 grams of Argon-40, how many half-lives have occurred
2 Half Lives.
How long does it take Venus to complete one revolution? Why does it take that long?
224.7 days due to distance from the Sun and gravitational pull
What is the difference between a white dwarfs and a supergiants.
White dwarfs have higher surface temperature and smaller mass compared to supergiants.
What evidence proves that the Taconic Mountains were uplifted?
What happens when a continental crust collides with a oceanic crust?
The oceanic crust subducts into the continental crust.
Which isotope would be best used to date a meteorite from outerspace?
Rubidium-87
