After reviewing the graph you have given with the question, there are several reasons why carbon 14 can't be used to accurately determine the age of organic remains that are 1 million years old.
A few of the reasons are; Carbon-14 has a short half life, after 1,000,000 years there wouldn't be enough carbon 14, and too little of the original radioactive sample would remain. Any of these choices are correct for the answer to the question you asked.
Answer:
Surface waves have a longer duration and higher amplitude than body waves.
Explanation:
The stark difference between an earthquake body and surface waves is such that they have longer duration and a higher amplitude compared to body waves.
There are two categories of seismic waves that usually accompanies an earthquake:
- body waves are faster and perpetuate in the subsurface. They reach the seismic station first and are discovered faster.
- surface waves arrives later and they cause the damage produced by most earthquake waves. They perpetuate on the surface.
- surface waves are the love and Rayleigh waves
- body waves are the primary and secondary waves.
