New oceanic lithosphere is able to form at mid-ocean ridges through the process of seafloor spreading. As tectonic plates move apart, magma rises from the mantle and solidifies to create new oceanic crust. This process contributes to the growth of the ocean basins and renewal of the Earth's lithosphere.

Was Wegener's continental drift hypothesis weakened because of viable mechanism for moving the continents was lacking?
Yes, one of the main criticisms of Wegener's continental drift hypothesis was that he was unable to provide a plausible mechanism for how the continents could move. This weakened his theory and it was not widely accepted until the development of the theory of plate tectonics, which provided a mechanism through the movement of Earth's tectonic plates.
Could an individual unable to absorb oxygen into the body perform cellular respiration?
An individual unable to absorb oxygen into the body is called dead, and is unable to perform cellular respiration.
Why was Leslie unable to do the project on Jacques cousteau?
Leslie was unable to do the project on Jacques Cousteau because all the books about Cousteau were checked out of the library.
Why unable to precipitate DNA?
Ethanol
Which cell type lacks a nucleus what functions would this cell be unable to carry out?
The mature red blood cell lacks a nucleus, and so is unable to reproduce.
What animals don't live in forests?
Whales, dolphins, and other oceanic creatures would be unable to live in a forest.

What causes Earth's plates to move?
A brief summary of this long answer can be found by viewing the related question. For more information please read on!This is a complex question and is a subject of continuing ongoing scientific research. A summary of some of the hypothesised causal mechanisms of plate movement (based on scientists current understanding of the process) is given below:The primary source of energy for the motion of the lithospheric plates is dissipation of energy from the earth in the form of heat transfer. This heat transfer causes convection within the mantle and this convecting mantle material is hypothesised to exert a drag force on the base of the lithosphere. This is known as Basal Drag and was thought to be an important driver of tectonic plate motion until recently when advances in geophysical imaging techniques (specifically 3D seismic tomography) allowed geophysicists to form a more detailed model of the structure of the mantle but were unable to locate the necessary large scale convections structures. Further to this, geophysicists no longer believe that the asthenosphere has the necessary stiffness or rigidity to cause sufficient friction on the base of the lithosphere to be a significant driver of plate motion.Gravity is also believed to play a role in the driving of plate motions, both at mid-ocean-ridges (MOR) and at subduction zones. Both these mechanisms are also linked to the dissipation of heat and convection in that they are reliant on variations in the buoyancy of the lithosphere as temperature changes occur as described below:When hot (and so low density, buoyant) mantle material rises at an MOR, it is intruded into the pre-existing oceanic lithosphere as well as extruded at the upper surface. This newly intruded material is at a high temperature and cools relatively slowly. As such the newly formed oceanic lithosphere is buoyant and rises relative to the older cooler oceanic lithosphere further from the MOR. Even though this younger lithospheric crust is buoyant it is still significantly denser than the underlying upwelling hot mantle material and so "slides" down away from the crest in a process known as gravitational sliding. This is considered a secondary driving force as it only acts in close proximity to the ridge and does not transmit load into the surrounding lithosphere (it does not "push" the lithosphere away from the ridge, it is instead dragged - the tectonic regime is tensile, not compressive).Another more significant gravitational driving force of plate motion is that caused by the old, cool and so low buoyancy oceanic crust that sinks back into the mantle at subduction zones and acts to drag the attached oceanic lithosphere towards the plate boundary. This is known as slab pull and is thought to be a significant driver of plate motions as it has been observed that tectonic plates with subduction boundaries tend to move with a higher velocity than those without. Subducting oceanic slabs also promote another driving force of plate motion known as trench or slab suction. This is a process where the movement of the downgoing slab promotes flow in the nearby mantle. This flowing mantle material is thought to exert a traction both on the downgoing slab and the overlying non subducting slab, pulling them both towards the subduction zone.It should be noted that not all plates have significant subduction boundaries and yet still undergo plate movements so it is possible that a combination of all these mechanisms influences plate movement (as well as the possibility that there is some as yet undiscovered driving force that has a significant role).The above is a simple summary of a complex topic and as has been stated the causal mechanisms that drive the motions of tectonic plates are not fully understood and as such the reader should remember that this is a current and active area of research in geophysics and so the hypotheses summarised above may be accepted, rejected or modified over time!For more information, please see the related link.
