Which best explains the difference between an explanation and an argument

   The explanation gives the reason as the cause of some fact or claim, while the argument provides support in the form of evidence or example in order to substantiate the claim.

Explanation:  An explanation is any statement, reason or justification that makes a certain belief, action or position clear. An explanation can also mean a scientific explanation or explanation in the learning process.

The argument is a reason or set of reasons, settings, which support a particular idea or theory. The argument may also mean the exchange of ideas and attitudes within a discussion when opposing opinions, i.e. when a claim is supported by an example that serves as an argument.
