By not being so much based on fact as explaining said facts. That is what scientific theories do, explain the facts and laws contained within them as far as possible. For example; evolution, the change in allele frequency over time in a population of organisms, is fact. The theory of evolution by natural selection explains much, not everything, about the fact of evolution.
They first form a theory then observe the empirical evidence which in science is enough but nowhere near enough in philosophy.
Observation and exact measurement, and theorizing, and testing, and experimenting to see if the theory is correct. Then evaluating, and if necessary rethinking, and starting again.
A scientific theory is based on serious, repeatable and reproductible experiments.
yes
You have it backwards. Theories are supported by evidence. Evidence is not supported by theories, evidence is simply observed.
why are theories sometimes replaced by new theories
Scientific conclusions are based on scientific evidence.
when enough evidence contradicts earlier ideas
There is not enough evidence to support these new theories. More tests and research needs to be carried out before these theories can be proved.

use scientific evidence to support your answer
why are theories sometimes replaced by new theories
I'm not exactly sure what kind of answer your looking for, but if your asking about decisions made based on scientific evidence. The reason statements are based on "Knowledge at the time" is because later evidence or findings might cancel out the current decision. scientific answers are based on the exploration of theories, and until all theories can be exhausted, there cannot be a single answer to the given question.
Scientific conclusions are based on scientific evidence.
Yes.
This a Study Island Question. The answer is "Scientific Theories are supported by evidence or data."
by falling in a hole
Scientific laws are based on scientific experiments, scientific conclusions after exhaustive tests, and they are also based on formerly scientific discoveries and experiments. Scientific evidence without a conclusive proof may be a false evidence. Scientific evidence doesn't exist. Science is not based on evidences, but on real results originated from a theory. Results are solid, palpable, real and cannot be doubted.
Scientific theories can be changed or replaced when there has been significant evidence for the change. The scientific method must be used to create a new hypothesis, which must then be proven.
Because non-scientists do not understand what a scientific theory actually means. It is not a random guess. Scientific theories are formed based on evidence and experimentation.The scientific community advocates evolution because all the evidence of life on our planet supports the theory.
