What was discovered about the properties of the mantle that provided evidence of the driving force of plate tectonics?

The asthenosphere, which is part of the upper mantle, is not completely solid. In fact, it is much like jello, due to the heat and limited pressure. The plates of the crust rest on this floppy layer, and the instability causes them to move about.
Convection currents move the magma, which then move the tectonic plates.

What was the main counterargument against wegners evidence?
1 counterarguement.... there was no drift because all is just as it was created. This theory works under the premise of creationism which disregards all evidence of Evolution OR If you are asking for argument were used against the theory of continental drift; it was rejected because there was no mechanism known that could cause continents to drift. It was revived when the theory of plate tectonics provided this mechanism.
What words Describe the land features that provided evidence for Wegener's hypothesis?

Why is plate tectonics a theory and not a law?
Despite what Creationist would have you believe (when debating other topics) theory does not mean hypothesis or speculation. In science, a theory is an explanation of the natural world that is well-substantiated by evidence. This includes a number of explanations that are so well-substantiated by evidence that there is virtually no doubt among scientists that it is the correct explanation. These include the theory of plate tectonics, the thoery of evolution, atomic theory, and germ theory.

How did the world react to Marie Tharp's new discovery?
Marie Tharp's new discovery of the Mid-Atlantic Ridge was initially met with skepticism by the scientific community, as her findings challenged existing theories of plate tectonics. However, as more evidence emerged supporting her mapping of the ocean floor, her work was eventually accepted and revolutionized the field of geology. Tharp's discovery provided crucial evidence for the theory of continental drift and plate tectonics.
What provided the force that pushed up californias sierra Nevada and coast ranges?

What process causes stresses in earth?
Plate tectonics, the movement of the large pieces of the earth's crust, give rise to great stress along the boundaries of the plates. Wikipedia has a post on plate tectonics, and a link is provided.
