What is a ridge push?

Ridge push is a geological concept where the force of gravity causes oceanic lithosphere to move downhill from a mid-ocean ridge, pushing tectonic plates away from the ridge. This process contributes to plate motion along with other forces like slab pull and mantle convection.


Compare and contrast ridge-push and slab-pull?

Ridge push is a proposed mechanism for plate motion in plate tectonics. Because mid-ocean ridges lie at a higher elevation than the rest of the ocean floor, gravity causes the ridge to push on the lithosphere that lies farther from the ridge.Slab Pull is is tectonic plate motion due to higher densities. Plate motion is partly driven by the weight of cold, dense plates sinking into the mantle at trenches.


It takes 100 000years for a plate to move about 14 kilometers calculate the rate if plate motion?

To calculate the rate of plate motion, divide the distance traveled by the time it took to travel that distance. In this case, the rate of plate motion is 14 kilometers divided by 100,000 years, which equals 0.00014 kilometers per year.


What is the thermal convection that drives plate motion is caused by what?

The thermal convection that drives plate motion is caused by the movement of molten rock in the mantle. Heat from Earth's core causes the mantle to circulate in a convection current, which in turn drags the overlying tectonic plates along with it, driving plate motion.


What drives plate motion?

Plate motion is primarily driven by convection currents in the Earth's mantle. Heat from the core drives these currents, causing magma to rise and cool near the surface, creating a continuous cycle of movement that pushes and pulls the tectonic plates. Other factors, such as gravitational forces and the sinking of cold, dense lithosphere at subduction zones, also contribute to plate motion.

What is scotch yoke mechanism?

Scotch Yoke Mechanism is a mechanism in which the rotary motion is converted to reciprocating motion, with a single link or bar. The reciprocating system has to be constrained along the guide ways for linear motion.


What models have been propose to explain the driving mechanism for plate motion?

Two main models have been proposed to explain the driving mechanism for plate motion: slab pull and ridge push. Slab pull suggests that the gravitational force acting on a denser oceanic plate sinking into the mantle pulls the rest of the plate along with it. Ridge push, on the other hand, suggests that the elevation difference between the elevated mid-ocean ridges and the lower trenches exerts a gravitational force that pushes the plates away from the ridges.

What is a tray mechanism?

a tray loading mechanism is a system of moving parts that changes an input motion and force into a desired output motion and force


What is The primary forces that cause plate motion are made possible by a mechanism called?

plate tectonics. The primary forces that drive plate motion are thought to be driven by mantle convection. This process involves the movement of heat from the Earth's interior towards the surface, causing the solid rock in the mantle to flow in a circular manner, which in turn moves the tectonic plates above it.


What is inversion of mechanism?

Inversion of a kinematic linkage or mechanism is observing the motion of the members of the mechanism with fixing different links as reference frame. Each time when a different link is chose as the frame link the mechanism shows different characteristics of the motion.
