Depends on whether all the theory is being contradicted or only a part of theory faces contradiction. For instance; the theory of evolution by natural selection would take a theory shaking hit if we found fossil rabbits in the Cambrian period, which has not happened. Only part of the theory of evolution by natural selection was contradicted by Mendelian genetics, when Mendel's much better heritability mechanism replaced Darwin's idea about blending inheritance. The theory only got stronger by this ratification.
If that new evidence is solid enough, it may require a revision of the theory. If it is just shaky and occurs because of some error in the experiment, it is usually discarded as uncredible.

If the challenge is successfully rebutted, the theory stands.

How did the new evidence support Hess's theory of seafloor spreading?
Umm Maybe by the way sea floor spreads apart along both sieds of a mid ocean ridge as new crust is added
How the evidence of the chemical reactions demonstrated bonding theory.?
New compounds are obtained because new chemical bonds are formed.
What is the reason that a theory might be replaced with a new theory?
a theory is an explanation to a specific question being studied. it has been tested many times. it might be replaced with a new theory because new information come and so the past information will be improved.
Is the big bang theory a load of crap?
It is the current working theory of the origin of the universe. It is the paradigm that Astronomy is based upon. But, new evidence is always being described. The theory itself might change as our knowledge grows.
How do mid ocean ridges support the idea of continental drift and the theory of plate tectonics?
New crust forms at mid-ocean ridges.
How long was it before new evidence emerged to support wegener's original theory?
In the 1960's scientists uncovered new evidence that seemed to support Wegener's theory.
If new evidence does not support a scientific theory scientists will most likely?
modify the theory or discard it altogether.
A physical representation of an atom is an example of a scientific?
If new evidence does not support a scientific theory, scientists will most likely
When was the first concrete evidence found to support the theory that new ocean crust formed at vents in the ocean floor?
1977!
How do scientists know that a new theory is accurate?
Because all of the observations and evidence are used for support.
How are scientific theories related to observations and evidence?
Scientist use scientific methods to test the new theory. They also examine all the evidence to see if it supports the new theory. Scientist accept a new theory when many test and pieces of evidence support it.
What happens when new information is dicoverd about a theory?
The theory is evaluated in the context of the new information. The information may support the theory, it may require a tweak to the theory to accommodate the new information or it may require a major re-think of the theory.
Can scientific theories change?
Yes, they can, if new evidence is discovered to support a change in the theory. Physical theories are not provable in the sense of mathematical theorems. They depend on evidence, and they can be disproved if enough contrary evidence comes up.
Under what conditions can a scientific model or theory change?
A scientific model can change if new evidence is found. If the new evidence that has been found contradicts the model or theory then a scientific model or theory can change.
What is a scientific theory that has been changed due to new evidence?
When new evidence is found, the theory is tested against the new evidence, if the theory and new evidence are compatible then the theory is confirmed, if the new evidence and the theory are not compatible, then this indicates the theory is wrong and the theory must be abandoned or modified. Sometimes a theory will predict that new things (evidence) will be discovered. In such cases when these things are discovered AS PREDICTED, the theory becomes stronger. For instance some of the outer planets were predicted (using orbital and gravitational theory and observation on the orbits of known planets) and they were later discovered close to where they were predicted to be.
Why is Einstein's theory of relativity an improvement on Newton's theory of gravity?
It will be replaced by a new theory when enough evidence is collected
