Can you please:
1. briefly explain the concept of radioactive decay and describe how it can be used to find the absolute age of rocks.
2. contrast relative age with absolute age and describe at least three methods of determining either.
3. compare advantages and disadvantages of renewable energy technologies.
4. briefly explain nuclear fission and fusion and summarize their advantages and disadvantages as sources of energy.
5. explain the basic function of a nuclear reactor.
Please help! I'm having lots of trouble understanding this stuff and I need help. Thanks a lot for any help!
I think it would benefit you more if you type what you think, and let us critique it.
