What is the relationship between transform boundaries and mid ocean ridges?
Transform boundaries exist where one plate slides past another without production or destruction of crustal material.
As explained in section 4.5, most transform faults connect segments of mid-ocean ridges and are thus ocean-ocean plate boundaries.
Some transform faults connect continental parts of plates..
What are the two ways transform faults move?
Transform fault, in geology and oceanography, a type of fault in which two tectonic plates slide past one another. A transform fault may occur in the portion of a fracture zone that exists between different offset spreading centres or that connects spreading centres to deep-sea trenches in subduction zones.
Where are transform faults found?
Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges. A smaller number connect mid-ocean ridges and subduction zones.
What are fracture zones in reference to mid ocean ridges?
Fracture zones are valleys that cut across midocean ridges, thus providing a passage for flow of cold bottom water from one ocean basin to another.
What is the orientation of mid ocean ridges to transform faults?
The spreading center or axis, commonly connects to a transform fault oriented at right angles to the axis. The flanks of mid-ocean ridges are in many places marked by the inactive scars of transform faults called fracture zones.
What are some examples of mid ocean ridges?
Mid-ocean ridges are typically half a mile to six miles wide and over a mile underwater. Two of the most well-known mid-ocean ridges are the Mid-Atlantic Ridge and the East Pacific Rise. As you might guess, most of the Mid-Atlantic Ridge is in the Atlantic, and most of the East Pacific Rise is in the Pacific.
How do transform faults move?
Plates glide along the fault and move past each other without destruc- tion of or creation of new crust. Although crust is neither created or destroyed, the transform margin is commonly marked by topographic features like scarps, trenches or ridges.
What landforms are created by Transform boundaries?
Transform boundaries represent the borders found in the fractured pieces of the Earth’s crust where one tectonic plate slides past another to create an earthquake fault zone. Linear valleys, small ponds, stream beds split in half, deep trenches, and scarps and ridges often mark the location of a transform boundary.
Why do transform faults occur?
Most transform faults are found along the mid-ocean ridges. The ridge forms because two plates are pulling apart from each other. As this happens, magma from below the crust wells up, hardens, and forms new oceanic crust. This is the ridge.
What causes transform boundaries to move?
The third type of plate boundary occurs where tectonic plates slide horizontally past each other. This is known as a transform plate boundary. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes. Places where these breaks occur are called faults.
Where are the transform boundaries located?
Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California’s San Andreas fault is a transform boundary.
What type of faults occur at mid ocean ridges?
Transform faults are commonly found linking segments of mid-oceanic ridges or spreading centres. These mid-oceanic ridges are where new seafloor is constantly created through the upwelling of new basaltic magma.
What is a transform fault characterized by?
The transform fault concept was introduced by Wilson (1965) and, distinguished from classic transcurrent faults, are (or were) active along their entire length and exhibit a sense of motion in the same direction of motion as the apparent offset of the major features.
How far below the surface are mid ocean ridges?
The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet). Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart.
Why does the mid ocean ridge have a zigzag appearance?
The reason the mid-ocean ridge has a zigzag appearance is because: it accommodates spreading of a linear ridge system on a spherical Earth. Turbidity currents are highly erosive and are thought to be responsible for the creation of deep-sea trenches.
