The accumulation of thick sediment layers along the boundaries of a continent is primarily associated with:
**A) Marine transgressions**
During marine transgressions, sea levels rise relative to the land, causing ocean water to encroach onto continental land. This process can lead to the deposition of sediments in coastal and shelf environments, resulting in thick sediment layers being laid down along the continental margins.
While marine regressions (B) and processes like subduction (C) and glaciation (D) can also influence sediments, they do not primarily lead to the accumulation of thick sediment layers at the continental boundaries in the same direct manner as marine transgressions.
