The Atlantic Ocean is expanding as the continents drift apart. This process is known as seafloor spreading, where new oceanic crust is formed along mid-ocean ridges. The movement of tectonic plates away from each other allows magma to rise and solidify, creating new crust and widening the ocean basin.
Because the tectonic plates which it sits upon are moving apart at the mid-atlantic ridge.
The Pacific Ocean is not expanding in the traditional sense. However, tectonic plates beneath the ocean are constantly moving, which can lead to the ocean floor spreading in some areas due to seafloor spreading along mid-ocean ridges.
The Atlantic Ocean is expanding. Plate tectonics are driving the eastern New World and the western Old World farther apart.
There is a rift down the center that pushes the ocean floor outward, expanding the ocean continuously. The rift is life a long volcano spewing out lava.
geologically speaking,an ocean has a rift system which works on expanding the ocean floor, while a sea has no rift system,the size is constant. the red sea can be considered an expanding ocean,yet it is called a sea because of its small size compared with the Atlantic ocean which has an expanding mid ocean rift system that runs north to south and surfaces in iceland.
The state of Maine is on the coast of the Atlantic Ocean
The Atlantic ocean
The Pacific Ocean is shrinking due to subduction, where one tectonic plate is being forced beneath another. This occurs at convergent plate boundaries where plates are moving towards each other. The Atlantic Ocean is expanding due to seafloor spreading, which happens at divergent plate boundaries where plates are moving away from each other, creating new oceanic crust.
