List 4 of the 6 ways to determine what a mineral is.
Luster: Metallic to dull characteristics. 2. Specific Gravity: Compares a mineral’s weight to that of an equal volume of water. 3. Color: Should never be the primary means of identification. 4. Hardness: Mohs’ scale measures this from 1 (soft) to 10 (hard). 5. Streak: Scraping a mineral and examining this powder. 6. Crystal Symmetry: Cubic, tetragonal, orthorhombic, hexagonal, monoclinic, ortriclinic.

What are some assumptions that go into radiometric dating and radioactive decay used to date rocks?
Assumptions include: radioactive atoms have, all changed at a constant rate, and that there is, a specific number of parent atoms to start with, based on how many parent and daughter atoms, they find in their sample. They also have to, assume that all the daughter atoms were formed, through radioactive decay
