Answer:
It is commonly known that the settling time of particles with smaller sizes is higher than that of particles with larger sizes. Therefore, the particles with smaller sizes are moved further offshore. Based on this fact, the proper arrangement will be to arrange the particles according to their sizes from those with the largest sizes (nearshore) to those with the smallest sizes (furthest offshore).

Answer:
Option (5)
Explanation:
The ultraviolet rays are found to be present in solar radiation and are allowed to be incident on the earth. These solar radiations are comprised of nearly 8% of UV rays. These UV rays are of three types, namely UV-A, UV-B and UV-C which are harmful to the living organisms on earth. Of all the three, the UV-B and UV-C are highly dangerous that can cause various skin diseases like cancer.
The presence of the ozone layer in the atmosphere acts like a blanket that does not allow these harmful UV radiations to enter into the atmosphere of the earth. The majority of the UV-A is able to reach the earth's surface, but they are not able to cause much harm. So, out of this 8% of total UV radiations, a little amount of it is successful in reaching the surface of the earth.
Thus, the correct answer is option (5).
