Do you think that the question is too technical for the beginners board?
It depends on what level you expect it to be answered. I would say: "each block builds upon the previous block. This ensures none of the blocks can be altered without breaking the chain".
Wikipedia would say (shortened):
A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a cryptographic hash of the previous block, a timestamp, and transaction data. By design, a blockchain is resistant to modification of the data.
But the real answer, including technical details, hashes and other stuff I can't reproduce, would be far above the level any user (new or experienced) would need to know. You can use Bitcoin without knowing those details.

Lol
I forget that all the time too. Archive it and create a new one.
