Detailed explanation-1: -The Atlantic Ocean is currently growing wider as its floor enlarges due to the process of sea-floor spreading. In sea-floor spreading, pieces of oceanic crust. move sideways against each other along a transform plate boundary.
Detailed explanation-2: -The Atlantic Ocean grows 1.5 inches wider every year. That’s because the tectonic plates undergirding the Americas are separating from those beneath Europe and Africa.
Detailed explanation-3: -Atlantic ocean is expanding due to formation of new crust at the mid-Atlantic ridge and westward motion of the North American Plate. Further Eurasian Plate is moving eastward and sliding over Pacific Plate and minor plates sinking in the Pacific ocean.
Detailed explanation-4: -As the magma cools, it is pushed away from the flanks of the ridges. This spreading creates a successively younger ocean floor, and the flow of material is thought to bring about the migration, or drifting apart, of the continents.
