Earth Science Core (S2157608) Name: ____________________

Date: ____________

Use the spaces below to take notes on the key concepts presented in this study.Main Idea #1: Stars are extremely dense masses that are so hot that nuclear fusion occurs within them.

Main Idea #2: When fuel is burned from within a star, it disrupts stellar equilibrium. The total mass of a star will help determine its life cycle.

Main Idea #3: Nebulae left over from a star’s death will collapse under their own gravity to form another star.
