Giving each block the hash of the previous block is the reason why the blockchain is arranged end to end. It also makes it very difficult to attack the blockchain as the attacker will have to change so many hashes of blocks from the particular block of interest till the latest block. That's classic thinking from the inventors of bitcoin.

You did justice to the technical part of blockchain's explanation. It's right to visualize each block being on top of the previous block. That gives a precise explanation to the concept of block heights.

Nice post.
