seashore
The edge of land that borders an ocean is called the coastline.
continental
The land under an ocean at the edge of a continent is called the continental shelf. This is the shallow submerged portion of a continent that extends from the shoreline to the continental slope.
The expanse of land known as a 'continental shelf' where seawater is shallow, before it drops off into the ocean.
Oh, dude, the edge of a continent is marked by the coastline where the land meets the ocean. It's like where the sand ends and the salty water begins, you know? So, if you're standing there with one foot on land and one foot in the water, you're basically straddling continents like a boss.
A river becomes an ocean when it has flowed to the edge of the land and into the open water; this place is called the mouth of the river.
You may be referring to the "shore." Sometimes, but not always, the shore is a "beach."
Bank or beach!
I don't know but the land along the edge of a country where the beaches are is called a coast. :)
Continental Shelves
You can't have a continent rise from land, but you can have land rise from the continental shelf, which may be under water, and that is called an island.
The true edge of a continent is typically marked by the coastline or shoreline where the land meets the ocean. This boundary is defined by geological features such as cliffs, beaches, or shallow coastal waters that separate the continent from the open sea. Geographers and scientists use various criteria to determine the exact edge of a continent, including tectonic plate boundaries and the extent of continental shelf.
