Are the ‘chaparrals’ (E. x: Chaparrals of California) and ‘moorlands’ or ‘moors’ (E. x: The English moors) similar? They are both characterized by sparse vegetation and heath growth, right? Is there any difference?

I personally don't think there's a difference.

the proximity of water was an advantage to western europe and its culture was able to flourish as a result. trade and travel by sea were easier and safer in historical times.

1. there are no mountains to protect it from the sea

2. and its has wet cool summers and wet, mild winters.
