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.

the berlin blockade was an international crisis that arose from an attempt by the soviet union, in 1948–49, to force the western allied powers (the united states, the united kingdom, and france) to abandon their post-world war ii jurisdictions in west berlin. in march 1948 the allied powers decided to unite their different occupation zones of germany into a single economic unit. in protest, the soviet representative withdrew from the allied control council. coincident with the introduction of a new deutsche mark in west berlin (as throughout west germany), which the soviets regarded as a violation of agreements with the allies, the soviet occupation forces in eastern germany began a blockade of all rail, road, and water communications between berlin and the west. on june 24 the soviets announced that the four-power administration of berlin had ceased and that the allies no longer had any rights there.
