The primary distinction between historic archeologist and prehistoric archeologist is that the former have access to written records.
Historic archeologist deals with the archeology if the recent past, with a short period of time. While the prehistoric archeologist deals with the time period prior to written records, it deals with a longer span of time.
GIS stands for Geographic Information Systems c:
Radius of earth as given in question = 6400 km
Height of the air balloon = 200 m
= 0.20 km
Now
Let us assume the distance up to which one can see from the balloon = d
Then
d=sqrt [<span><span><span>(R+h<span>)2</span>−<span>R2]
</span></span></span> = sqrt [</span><span><span>2Rh+<span>h^2]
= sqrt [2 (6400 * 0.20) + (0.20)^2]
= sqrt [(2 * 1280) + 0.04]
= sqrt [ 2560 + 0.04]
= sqrt [2560.04]
= 50.6 km
A person in the balloon can see up to a distance of 50.6 km. I hope the answer has helped you.</span></span></span>

Answer:tidal range is dictated only by the gravitational attractions of the sun and the moon
Explanation:tidal range is not constant but
