Mid-ocean ridge cross-section (cut-away view) A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate ...
A bathymetric map of the Mid-Atlantic Ridge (shown in light blue in the middle of the Atlantic Ocean). 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.
Juan de Fuca Ridge. Coordinates: 46°N 130°W. Location of the Juan de Fuca ridge off the coast of North America. Magnetic striping on either side of the ridge helps date the rock and determine spreading rate and age of the plate. The Juan de Fuca Ridge is a mid-ocean spreading center and divergent plate boundary located off the coast of the ...
Map of the Chile Rise and its fracture zones in Nazca and the Antarctic Plates Active Pacific Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region. Since the map was prepared ages not shown of south-west Pacific and north Pacific ocean floors may have been characterised.
A seafloor map captured by NASA. Bathymetry (/ bəˈθɪmətri /; from Ancient Greek βαθύς (bathús) 'deep' and μέτρον (métron) 'measure') [ 1 ][ 2 ] is the study of underwater depth of ocean floors (seabed topography), lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography.
The Explorer Ridge is a mid-ocean ridge, a divergent tectonic plate boundary located about 241 km (150 mi) west of Vancouver Island, British Columbia, Canada. It lies at the northern extremity of the Pacific spreading axis. To its east is the Explorer Plate, which together with the Juan de Fuca Plate and the Gorda Plate to its south, is what ...
e. An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 and 6,000 metres (9,800 and 19,700 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth 's surface. [1][2] They are among the flattest, smoothest, and least ...
The simple result is that the ridge height or ocean depth is proportional to the square root of its age. [28] Oceanic lithosphere is continuously formed at a constant rate at the mid-ocean ridges. The source of the lithosphere has a half-plane shape (x = 0, z < 0) and a constant temperature T 1.
