What is the difference between Tea Biscuits and Scones?

Yaa, as far as i know there is a differece between tea biscuits and Scones. what i know , the main difference is that scones tend to have eggs and are sweeter and more elaborate , while biscuits dont include eggs and have simpler , more savory ingredients. that doesn't mean a biscuit has to be plain. it's just that biscuits are more likely to have cheese or fresh or dried herbs in them rather than, say currants or chocolate chips.
