1. What is the youngest rock layer on the figure? Explain.

Explanation:

The many horizontal layers of sedimentary rock illustrate the principle of original horizontality (Figure below). The youngest rock layers are at the top and the oldest are at the bottom, which is described by the law of superposition.

well this is going to be a long answer lol ok so the visigoths were a branch of the goths who frequently raided rome, uh the hunas attacked the guptas a lot and weakened them, uuhm of course the romans used math and science in there every day lives i mean they had a whole empire to run, and rome was split into east and west by a general named diocletian. hope this you! : )
