In this process, there’s a buildup of a VERY heavy isotope, then as beta- decays occur, you march up in atomic number and produce heavy product.

• S Process

• R-Process

• Nuclear Fission

• Proton-Proton Reaction

What is required to make nucleosynthesis happen (check all that apply)?

• a high speed collision

• a very high temperature

• a black hole

• violent surface interactions like solar flares

What is responsible for 85% of the energy from the sun?

• the break down of heavy elements by fission

• the burning of plasma

• hydrogen fusing into helium in the sun's core

• the burning of electrons from the outsides of atoms

When a star runs out of hydrogen, it changes dramatically. The star cools, gets larger, and becomes a red giant or supergiant depending on the mass of the star. In the largest stars what happens?

• comets and meteorites eject new elements into the star

• larger atoms like oxygen and iron form

• multiple new stars are formed as the large star splits

• red and blue light move around the core
