2 Peter 3:10 speaks of the day of the Lord, which is the same day as described in Matthew 25. once the Judgement is complete, “and then” indicates the earth will destroyed immediately after Matthew 25 concludes.
there is no literal 1,000 year reign described in either book.
You might want to cross reference Matthew 24 use of “Coming of the Son of Man” with other NT and OT references. In both testaments there are several events to happen on the Day of the Lord. Melting everything is just one.
That is unless you don’t see OT prophecies yet to be fulfilled as irrelevant.
