Question

Answer 1

D for sure, and I think A as well

Answer 2

Relative dating is done by comparing the locations of the items being dated. If you look at a building, relative dating allows you to say that the first floor was built before the top floor. If you look at an archeological dig, you can say that, in general, the dirt and rock on the surface are younger than the dirt and rock and items beneath them and that the deeper you dig, the older the items you're looking at. If you look at a series of fossils, say shells or mammal bones, you may be able to see the development of structures that give an indication of which fossils are older.
In all these instances, you may be able to tell the relative ages of the items being examined, but you will not necessarily know the actual ages (101 years, 10000 years, 100 million years) or the amount of time between an older and a younger specimen.
