King's Trough even an oblique meteor impact. The trough, being in an apparently geologically stable region, has been studied as a possible location for radioactive waste disposal. King's Trough King's Trough is an undersea trough in the Atlantic Ocean. It is located on the east side of the Mid-Atlantic Ridge, northwest of the Açores-Biscay rise and roughly 400 km NNE of the Azores. It is about 400 km long, running in a NW–SE direction. To the east it branches into the Peake Deep and Freen Deep. The center depth is 4500 m. Surrounding the trough are high ridges and seamounts, such as
Gulf Trough of roughly , material born of erosion began building up more rapidly in the Gulf Trough, due to the uplifting of the Appalachian Mountains to the north, which provided the primary source of siliciclastic material transported south via rivers and streams. By the Early Miocene, the trough was filled, and materials continued to move southward covering and replacing the carbonate-depositing marine environment with sands, silts, and clays; these sediments created the peninsula on which terrestrial flora and fauna could become established.
