Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How heavy is Type II supernova?Stars with initial masses typically between 8 and 25 solar masses
2. What is the explosion mechanism?Core-collapse supernova driven by a neutrino-heated shockwave
3. What is the primary nucleosynthetic role?Major source of elements heavier than iron via the r-process
4. Why does a star explode in a Type II supernova?The star's core collapses into a very dense proto‑neutron star, and a shockwave bounces back, blowing the outer layers into space.
5. Where do the elements from a supernova go?The material from the explosion spreads into space, adding new elements to the galaxy and helping future stars and planets form.

Core-Collapse Supernova: A supernova resulting from the gravitational collapse of a massive star's core.
Neutrino-Driven Explosion: A supernova model where neutrinos play a key role in reviving the stalled shockwave.
r-process: Rapid neutron capture process responsible for synthesizing heavy elements during supernovae.
