The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian plate and the African plate, north and south of the Azores triple junction ...
The coastal Atlantic plain features nearly continuous barriers interrupted by inlets, large embayments with drowned river valleys, and extensive wetlands and marshes. [2] The Atlantic plain slopes gently seaward from the inland highlands in a series of terraces.
The plate collisions that formed the core of our continent left behind a striking structural trend. Ridges and valleys are strongly aligned along this northeast–southwest trend. Lake Superior is an example of this northeast–southwest structural trend. Ridges of erosion-resistant rock rise above valleys and carved into weaker rock units. [15]
Definitions of the geographic components of the Mid-Atlantic region differ slightly among sources. [15] Generally speaking, the region is inclusive of the states of Delaware, Maryland, New Jersey, New York, Pennsylvania, Virginia, and West Virginia, and the federal district of the District of Columbia, with some additional sources including or excluding other areas in parts of the Northeast ...
Continental-continental divergent/constructive boundary Oceanic divergent boundary: mid-ocean ridge (cross-section/cut-away view). In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
The Mid-Atlantic Ridge stretches 10,000 miles from north to south, and is considered “the longest mountain range in the world and one of the most prominent geological features on Earth,” NOAA ...
