Difference between blogs and websites

Last week we were given the task of observing the difference between a blog and a website. I was given the subject, "cars" and I found the following:

www.carmagazine.com

www.carscoop.co.uk

I found that on a blog it's more like a journal/diary, the language is different,informal.The overall look is different, theres opportunity for peoples points of view, less images but more adverts.

On a website it's more structured, factual, contains more links and is read only.
