What cause transactions to split in to seperate ones?

Just browsing blockchain and I see things like this:



Does it all go to the same address? Surely it can't be a fee for that value? The values also seem to go up and down?

When bitcoins are sent, all the bitcoins in an "output" of an address must be sent, even if it is too much. The wallet sends the correct amount to the address you want, and sends the rest (called the "change") back to you.

Or the user sent coins specifically to 2 different addresses.
