Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Hi Suyash,
Greetings!
The correct answer option is (D). Beach Sediments.
Thank you.
will you please explain
Hi Suyash,
Greetings!
Here is the explanation of your question.
Wind, waves, and currents constantly move and redistribute coastal sediments along shorelines. Beach sediments that have been transported great distances will be sorted according to grain size. For example, Gulf coast sediments may have traveled the length of the Mississippi River. Winnowing of more uniform sediment shapes and sizes results in a beach with well-sorted sediments. In contrast, poorly-sorted sediments are composed of a variety of sediment shapes and sizes. Low-energy conditions that allow fine sediments to settle from suspension must exist for the formation of muddy or sandy beaches. High-energy conditions are typical of rocky beaches that allow for the transportation of coarser sediments. Extreme storm events are necessary to move the largest sediments (e.g., boulders).
Thank you.
