Correct punctuation

If all of the salt in our vast oceans was dried out, it would cover all the land in the world at a depth of five feet.

Explanation:

The given sentence is an example of the second conditional.

Conditionals are sentences that tell us what condition needs to be fulfilled in order for something to happen. They consist of two clauses - the main clause and the if-clause. The if-clause is the one that contains the condition. These clauses are always separated by a comma.

Every sentence ends with a period, question mark, exclamation mark, or ellipsis, depending on the purpose of the sentence and the emotion it conveys. The purpose of the given sentence is to inform, which means that it should end with a period.

This means that this sentence should be corrected like this:
