Mid-Atlantic Spreading, which leads to increase in the length of the Atlantic oceans floor.
The tectonic plates are separating and growing more ocean floor (seafloor spreading).
The mid-atlantic ridge is a good example
It was formed when there was linear gap formed below at the ocean floor... So when the hot magma came out from it, it began to cool and solidify forming mid atlantic ridges
The Atlantic Ocean is gradually getting bigger because of the sea-floor spreading that is happening. Sea-floor spreading is the process in which new oceanic lithosphere is made. And this mostly happens at Mid-Atlantic ridges. This is the process in which magma from under the Earth seeps to the surface and gradually solidifies. F.Y.I. they sift apart making magma rise from the earths manntle. The magma then turns into more crust that has been happining for mllions of years.
North Atlantic Oscillation
Mid-Atlantic Spreading, which leads to increase in the length of the Atlantic oceans floor.
The prominent sea floor feature found in the central Atlantic ocean is called the Mid Atlantic Ridge.
Sea floor spreading
This is because when one divergent boundary is occurring (more sea floor being made), convergent boundaries are occurring (the sea floor is being consumed) on the other sides of the plates, such as what is occurring at the Mariannas Trench in the Pacific Ocean.
At the mid-atlantic ridge, where the ocean floor is spreading.
tsunami's would occur
Atlantic
yes
Mid-atlantic ridge
That would be the Mid-Atlantic Ridge.
The oceanic crust of the Atlantic Ocean floor is attached to the continental crust of the continents around the ocean. So as the Atlantic's Ocean floor spreads, the continents along its edges also move. Over time, the whole ocean gets wider.
