What is drowned coastline?
A "drowned" coastline - also called a "submergent" coastline - is an "old" continental edge that has been eroded, and is consequently flatter, with a shallower topography. It becomes "drowned" as sea levels rise, or as the land subsides - creating features such as large estuaries (Chesapeake Bay, for example) as old river valleys are submerged. The reason the East Coast is mostly submergent is because the continent is moving West - toward the Pacific and San Juan de Fuca oceanic plates. As the continent collides with these oceanic plates, it creates a new "emergent" coast along the west coast of the US and Canada - with steep mountains and volcanoes. In contrast, the East coast continues to erode over time, as there is no mountain building occurring (no collision with other tectonic plates).
