Answer:
abyssal clay is not an example of biogenic sediments .
Explanation:
Any sediment containing more than 30% of organic matter in it , is called as biogenic sediment or biogenic ooze.
The two most common types of biogenic oozes are calcareous and sileceous.
abyssal clays are the fine grained sediment particles that are settled in the deep ocean basins.
abyssal clay mostly consists of land derived eroded particles and have less than 30% of organic matter in them ,
Hence , abyssal clay is not an example of biogenic sediment.

Explanation:
Horn can be simply defined as the pyramidal peak that is formed at the high elevated region that are mostly covered by ice. This is formed when the glaciers erodes three or more aretes.
Mass wasting refers to the downward movement of rocks, or broken fragments or sediments that are primarily caused due to the influence of gravity.
Moraine usually refers to the accumulation of sediments and rocks that are mixed with ice, and these are unsorted in nature and are deposited when these particles are carried downward by the movement of glaciers.
Striations can be simply defined as scratch marks or grooves that are formed when rock undergoes thrusting or faulting.
Talus is defined as the accumulation of broken rock fragments that are found at the base of a mountain or cliff.
