An independent clause expresses a complete thought and can stand alone as a sentence: A meteorite crashed through their two-story house.
Two or more independent clauses can be combined with coordinating conjunction words such as and, but, or, so, and yet. Use a comma before the conjunction.
Neighbors said they hear a terrific noise, yet no-one reported it to the police.
Mr. and Mrs. Fausset's house was destroyed, so they moved.
We can talk about a past event using a time clause with when, as soon as, before, after, while, until, and since. When the time clause comes before the main clause, use a comma between the two clauses.

Use conditional sentences with if to talk about real causes and results. You can also use when in place of if.
Present Facts — use the simple present tense in both clauses: When a meteoroid enters the earth's atmosphere, chemical interactions and gasses cause it to heat up and form a fireball.
Future Facts — use the simple present in the if-clause and the future with will in the result clause: If you don't leave now, you will be late.
May/Might — use may/might in the result clause to suggest something is possible, but not certain: If you see a meteorite falling through the sky, it may be a stony meteorite, or it might be an iron meteorite. The third type of meteorite is a stony-iron meteorite, but these are very rare.
