Question below

is deep marine sediment not well sorted,?

kindly answer

it is because the deeper the water the more fine grained and well sorted sediments

Sorting is mainly controlled by the transporting agent (wind only transports fines - well sorted deposits, glaciers moves everything - poorly sorted deposits, and water is variable depending on amount of energy).. So clearly in marine environment the deposition of various sediments takes place according to the energy conditions... Like a weak energy cannot deposit or transport the coarser grains while one can see that as depth increases the sediments are mainly mud or clay dominating which surely leads to the conclusion that deep marine sediments are mostly composed of finer sediments.... Also best way to understand this is your turbidity currents which dominate deep marine (abyssal) and the sediments are hence poorly sorted... I'm hereby attaching a plot so that you can see the sorting of the sediments and their variation with deep marine environment... In turbidities the sediments remain in suspension because of fluid turbulence and this allows suspension settlement and this is why these deposits are characterized by poorer sorting. (Don't confuse it with the fluvial sediments which shows same characteristics but the difference is that the sediment size in fluvial is much coarser than in turbidity).

So you can say that in deep marin environment the sediment like clay mud are more pronounced as compared to sand or other coarser sediments..... For more information go through the marine environments section given in ravindar kumar..... Where you will get to know about clay line and mud deposited in deep oceans... (just like in your pacific ocean at depth of about 3-4 km you will get red muds, which is surely a fine sediment).

okay.thank you

sir wind action also forms facetted pebble

is deep marine sediment not well sorted?

it is because the deeper the water the more fine grained and well sorted sediments

sir please clear

Yes, wind action also form facated pebbles. Even, facated pebbles are most commonly found in Aeolian Environment.

Deep marine sediments can be well sorted in exceptional cases. However, in general deep marine sediments are poorly sorted

ok sir thank u
