How are run on sentences and compound sentences different?

Basically, a run on sentence is a sentence that has two complete sentences that do not connect properly. An example of this would be "I am cold I wore a blanket" to correct this you could say "I am cold, so I wore a blanket"

A compound sentence would be a sentence with two independent clause, joined by a coordinating conjunction. An example of this would be "I will go shopping or I will go camping"

Hope this help you.

it is the background information on the characters and setting explained at the beginning of the story. the exposition will often have information about events that happened before the story began. the exposition is often the very first part of the plot.
