18 Which of the Following Are Mechanisms for Plate Motion

Figure 432 Models for plate motion mechanisms Steven Earle Physical Geology. On world maps seismicity tends to locate along linear belts which define more active deformation compared to more.

Fig 1 Plate or disk cam.

. Convection in the Mantle. The part of the eye thats similar to the film of a camera is the RetinaUser. When two plates slide past each other Fig.

The North American Plate for example rotates counter-clockwise. Movement in the mantle. When one plate plunges beneath another Fig.

Some of the important causes are as follows. As oceanic lithosphere is formed at spreading ridges from hot mantle material it gradually cools and thickens with age and thus adds distance from the ridge. Violet light is preferable in a photographers darkroom.

ADisk or plate cam The disk or plate cam has an irregular contour to impart a specific motion to the followerThe follower moves in a plane perpendicular to the axis ofrotation of the cam shaft and is held in contact with the cam by springs or gravity. Pacific plate Australia plate Africa plate Scotia plate Nazca plate South America plate. Seismic Locations and Focal Mechanisms.

Formation of oceanic crust. Boundaries between the plates are of three types. Plate motion driven by local convection currents that exert a downward pull on plates in subduction zones at ocean trenches.

Log in with Facebook Log in with Google. Alem B mechanism book. The authors of the theory of plate-tectonics have proposed several different causes for the plate-motions.

A mechanism that contributes to plate motion in which cool dense oceanic crust sinks into the mantle and pulls the trailing lithosphere along ridge-push a mechanism that may contribute to plate motion. JaimienHicks JaimienHicks 12302016 History High School answered Which one of the following has not been proposed as a mechanism of plate motion A slab-pull. Mechanism of plate motion in which the descending slab pulls on the plate b.

The major mechanism of plate motion as the upward flow of hot less dense mantle material and the downward flow of cold dense material drives plate tectonics. Plate motion driven by friction between the convection currents in the asthenosphere and the more rigid overlying lithosphere. The part of the plate around the South America plate is moving northwards and a little east.

Cam is a mechanical component which is a rotating circle or eclipse about the minor axis of the Follower. Which one of the following has not been proposed as a mechanism of plate motion A slab-pull B ridge-pushC m Get the answers you need now. The explanation is that plates move in a rotational manner.

95 Mechanisms in of Plate Motion 10 Terms. Earth Science 10 Terms. According to many authors plate motion is driven by the higher elevation of plates at ocean ridges.

Mechanism of plate motion in which the force of new crust formed at the high ridges pushes on the plate c. Is the basic force that drives plate tectonics. As it has already been explained new crust is formed in zones of spreading.

Causes oceanic lithosphere to slide down the side of the oceanic ridge. Divergent ie moving apart convergent ie moving together and transform moving side by side. Which one of the following has NOT been proposed as a mechanism of plate motion.

All of the above. When two plates are pushed apart Fig. We present a revised global plate motion model with continuously closing plate boundaries ranging from the Triassic at 230 Ma to the present day assess differences between alternative absolute plate motion models and review global tectonic events.

Which of the following are mechanisms for plate motion. Which of the following are mechanisms for plate motion. Red light is less bright than violet light.

All of the above. Mechanism of plate motion in which the force of new crust formed at the high ridges pushes on the plate Mantle convection The major mechanism of plate motion as the upward flow of hot less dense mantle material and downward flow of cold dense material drive plate tectonics. Since this crustal for mation is a continuous process the new crust pushes the earlier.

The motion of plates can be described in four general patterns. Remember me on this computer. The part of the plate around the Australia plate is moving southwards.

The mass properties of light are invariable. Start studying Earth Science - Section 94 - Mechanisms of Plate Motions. Chapter 174 12 Terms.

Because violet light has more energy than red light A. Some compelling arguments in favor of. When two continental plates are shoved together.

It involves the oceanic lithosphere sliding. Learn vocabulary terms and more with flashcards games and other study tools. Is thought to be the primary downward arm of convection flow in the mantle.

The Eurasian Plate rotates clockwise. The following data refer to the lengths of links of a six-link mechanism in which the rotary motion of the input link 2 is transformed to the horizontal linear motion of the output slider 6. Earthquake Locations The systematic location of seismic events in a region can be used to identify causative seismic faults.

Up to 24 cash back a. Slab-pull ridge-push mantle convection or crust-core convection. Violet light has a higher wave frequency than red light.

Enter the email address you signed up with and well email you a reset link. Close Log In. I Fixed link 1 A0B0 60mm ii Input link 2 A0A 25mm iii Coupler link 3 AB 85mm Follower link 4 BB0 55mm v Connecting rod 5 CD 60mm.

Hence it can be explained easily that Cam is a mechanical component that transmits reciprocating oscillating or linear motion to Follower. Gravitational sliding away from a spreading ridge. Click here to sign up.

In this model plates move through a combination of pull from the weight of the subducting edge of the plates and through the outward pushing of an ocean ridge where magma is rising and forming new crust Figure 432. OTHER SETS BY. YOU MIGHT ALSO LIKE.
