Why doesn't the sediment record extend back to the time of the origin of the ocean?

Subduction zones in convergent boundaries push sediments into the mantle which is where they are destroyed and that is why no sediment records date back more than 180 years ago

What are the main methods and concepts in the field of sedimentology?
Sedimentology is the study of modern sediments and the processes by which they were formed. Scientists reconstruct past environments by comparing features of modern sediment with those of rocks on record. The principle of lateral continuity states that unless there is some obstruction, sediment will extend laterally until friction or topography causes it to stop.
A break in the rock record deposition of sediment has been interrupted is referred to as a?
A gap in the geologic record of rock formations is called an uncomformity.

Why doesn't one region on earth contain a record of all geologic time?
There will only be a record of a given part of geologic time if sediment was laid down at that time. For any given time period, there are regions in which sediment was not laid down. Addtionally, even where the sediment was laid down, some may been eroded and the rock record destroyed. Additionally, in a region where rock from one time period are expossed, rocks from older periods, if they exist, will bur buried, often too deep to be accessible.
What is the origin of the expression set the record straight?
To set the record straight means to make a statement that purports to make a more accurate telling of history or known facts and rumors. The origin is believed to refer to the act of straightening out a skipping record, but it actually predates recorded music by many years.
What are two ways that a rock layer can cause a gap in geologic record?
When rock layers are eroded or when a sediment is not deposited for a long period of time.
Certain blank that form sediment are considered an indicator species?
Certain microorganisms, such as diatoms and foraminifera, that form sediment are considered indicator species. These organisms have specific habitat requirements and environmental tolerances, so their presence or absence in sediment can provide valuable information about the conditions of their habitat, including water quality, temperature, salinity, and nutrient availability. Their abundant fossil record in sediment also aids in paleoenvironmental reconstructions.
