What's the difference between a miner and a node?

Could you please elaborate on the key distinctions between a miner and a node in the realm of cryptocurrency? I'm curious to understand how these two entities contribute differently to the maintenance and operation of a blockchain network. I've heard miners are responsible for verifying and adding new blocks to the chain, while nodes facilitate the transmission of transactions and maintain a copy of the ledger. Could you further clarify the roles and responsibilities of each, and perhaps highlight any other significant differences that set them apart? Your insights would be greatly appreciated.
