It is because "more" is not an adjective. For that reason, "more amount" makes no sense.

"More" alone is incorrect in "The amount of information becomes more" because it needs a noun (e.g., more detailed, more significant). "Less" works alone in "The amount of information becomes less" because it naturally quantifies uncountable nouns like "information." "More" is correct alone in "He's tearing it up more" because it's an adverb modifying the verb.

Correction: ❌ The amount of information becomes more. → ❌ Incorrect ✅ The amount of information increases. → ✅ Correct ✅ There is more information. → ✅ Correct Explanation: "More" alone is usually a comparative and needs a reference (e.g., more than before). In your incorrect sentence, "becomes" is a linking verb, which typically connects a subject to an adjective or noun, not a comparative word like "more." However, "less" works because it can function as a quantifier without a comparison (e.g., There is less noise). Why "He's tearing it up more" is correct: "More" works as an adverb modifying "tearing up" (a verb), meaning to a greater extent. Tip: When talking about an increasing quantity, use "increases" or "there is more" instead of "becomes more."
