what seafloor structures you would encounter if you could walk underwater from the United States to Europe

The seafloor structures that will be encountered are shelf, slope, rise, abyssal plain, seamounts, and mid-ocean ridge/rift valley.

Explanation:

The Atlantic Ocean is the second-largest ocean in the world. It is divided into two subdivisions, the North Atlantic Ocean and South Atlantic Ocean. The North Atlantic subdivision is the one located between North America on one side, and Europe and Northern Africa on the other side.

If we were to walk from North America to Europe on the ocean floor, then the first structure we will encounter will the relatively wide continental shelf. Next will come to the slope and rise where the seafloor sharply becomes much deeper. Once we reach the bottom of the ocean we will encounter the abyssal plain, and in the abyssal plain, there are also seamounts sharply rising above the seafloor. In the central part of the ocean, we will encounter the mid-ocean ridge, which is where the rift valley is located. After that, we will encounter the same structures that we already encountered just in a reverse manner, with abyssal plain and seamounts coming first, then sharp elevation as we come to the rise and slope, and a relatively small continental shelf.
