Here's why:
* Subject-Verb Agreement: "Snow" is the subject, and "fell" is the verb, making the sentence grammatically correct.
* Conjunction: The conjunction "and" connects the two clauses, showing the relationship between the snow falling and covering the fields.
* Clarity: Using "the" before "fields" makes it clear that we're talking about specific fields.
You could also say: Snow fell, covering the fields like a blanket. This is a more concise way to express the same idea, using a participial phrase to combine the two clauses.
