Answer 1

The answers they're looking for are "absolute" and "relative". These are not specific techniques, but are two categories of geologic dating.

Answer 2

I am guessing here:

Carbon dating for exact dating.

Formation or positional dating for comparative ages.

Answer 3

radioactive; relative

Answer 4

Absolute and relative.

Answer 5
