Visual Geography is a nice site with images, information, and quizzes about 85 countries around the world. Primary Resources blog posted about it today.
The text is accessible to Intermediate English Language Learners, and the images are obviously good for students of all levels. I like the quizzes it has about each country, and I also really like a neat feature called “Compare.” You can pick any two countries and easily compare their demographic data with a click of the mouse.
I’ve placed the link on my Geography page under Sites That Cover Many Areas.
