What is the mid-ocean ridge and where is it located?
Mid-Atlantic Ridge, submarine ridge lying along the north-south axis of the Atlantic Ocean; it occupies the central part of the basin between a series of flat abyssal plains that continue to the margins of the continental coasts.
What type of stresses are associated with a mid-ocean ridge?
Compressive Stress between Two Mid-Ocean Ridges.
Where is there a mid-ocean ridge?
The Mid-Atlantic Ridge extends from south of Iceland to the extreme South Atlantic Ocean near 60° S latitude. It bisects the Atlantic Ocean basin, which led to the earlier designation of mid-ocean ridge for features of this type. The Mid-Atlantic Ridge became known in a rudimentary fashion during the 19th century.
What is the function of the Mid Oceanic Ridge?
Mid-ocean ridges are the longest, largest and most voluminous magmatic environment on Earth. Ridges are the site of new lithospheric and crustal production that may be subsequently subducted into the mantle and recycled, or involved in magma-producing dehydration reactions that slowly build up continental crust (Fig.
What occurs in the mid-ocean ridge?
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
What formed the Mid-Atlantic Ridge?
divergent plate boundary
Description: The Mid-Atlantic Ridge (MAR) is known as a mid-ocean ridge, an underwater mountain system formed by plate tectonics. It is the result of a divergent plate boundary that runs from 87° N – about 333 km (207 mi) south of the North Pole – to 54 °S, just north of the coast of Antarctica.
Which type of stress is associated with the convergent plate boundary?
Compression
Compression is the most common stress at convergent plate boundaries. Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart.
What are the types of stress in plate boundaries?
Stress is the force applied to a rock and may cause deformation. The three main types of stress are typical of the three types of plate boundaries: compression at convergent boundaries, tension at divergent boundaries, and shear at transform boundaries.
What is the mid-ocean ridge system?
The mid-ocean ridge is a continuous range of undersea volcanic mountains that encircles the globe almost entirely underwater. It formed and evolves as a result of spreading in Earth’s lithosphere—the crust and upper mantle—at the divergent boundaries between tectonic plates.
What is a mid-ocean ridge simple definition?
Definition of mid-ocean ridge : an elevated region with a central valley on an ocean floor at the boundary between two diverging tectonic plates where new crust forms from upwelling magma.
What type of plate boundary is occurring in the Mid Atlantic Ridge?
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.
How is the mid-ocean ridge formed?
It formed and evolves as a result of spreading in Earth’s lithosphere—the crust and upper mantle—at the divergent boundaries between tectonic plates. The vast majority of volcanic activity on the planet occurs along the mid-ocean ridge, and it is the place where the crust of the Earth is born.
What are four identifying characteristics of mid-ocean ridges?
Formed from Fracture Zones. Despite encircling the earth and make a long line of ocean ridge,ocean ridge itself does not come in the form of straight and defined
What type of Boundry is associated with mid-ocean ridges?
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
What is important about the mid-ocean ridges?
Mid-ocean ridges are geologically important because they occur along the kind of plate boundary where new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a “spreading center” or a “divergent plate boundary.”
What is an example of a mid-ocean ridge?
The most prominent examples of the mid-oceanic ridge transform zones are in the Atlantic Ocean between South America and Africa. Known as the St. Paul, Romanche, Chain, and Ascension fracture zones, these areas have deep, easily identifiable transform faults and ridges.
