Fusion and The Sun
This process releases energy inside the Sun's core.
Nuclear Fusion
This shift in the light from distant galaxies indicates that many are moving away from us.
Redshift
Stars make new elements through this process.
Fusion
True or false: More massive stars generally live longer than less massive stars.
False
What is the most popular social media platform?
During fusion in a stable star like our Sun, hydrogen combines to form this element.
helium
These three letters name the leftover radiation from the early universe.
CMBR
Hydrogen fusion primarily produces this element.
helium
As stellar mass increases, the rate of fusion generally does this.
increases/get's faster
What is Chick-Fil-A's slogan?
Eat More Chicken
Energy produced by fusion eventually reaches Earth in this form
Radiation/Electromagnetic Radiation
The universe contains large amounts of these two simple elements, matching predictions from the Big Bang model.
hydrogen and helium
Two major factors determine which elements a star can produce. Name them.
star's mass and stage of life?
Complete the pattern:
More mass → ______ fusion → fuel used faster → ______ lifespan
faster;shorter
what is the smallest country in the world by land area?
Vatican City
Gravity pulls inward on a star. What helps keep a stable star from collapsing?
outward pressure associated with energy from fusion
Redshift from many distant galaxies provides evidence that the universe is doing this.
expanding
Stellar fusion in massive stars can produce elements up to this element.
iron
A massive star contains more fuel than a smaller star. Why can it still have a shorter lifespan?
Its greater mass creates conditions that cause fusion to occur faster, so it uses its fuel more quickly.
What blood type is the universal red-cell donor?
A model shows the sun producing energy by burning hydrogen in a chemical reaction. Identify the error in the sentence.
The sun's energy is produced by nuclear fusion, not chemical burning
Name all three major pieces of evidence for the Big Bang that we studied.
What are redshift, CMBR, and the abundance/composition of hydrogen and helium?
Explain why stars are sometimes called “element factories.”
Stars use fusion to transform lighter elements into heavier elements throughout their lives.
A star has much more mass than the Sun and eventually becomes unstable. What major stellar event could occur?
Supernova
