This is an extremely well-written and informative book about a perrennial kids' favorite--SAND. It is also fun and very, very attractive. The publisher, National Geographic, knows how to put a children's book together. I would suggest this book for nursery school classrooms, for summer vacation gifts, and for any child who asks, What is Sand? Great job!

Although this is an enjoyable read the book is absolutely riddled with unacceptable mistakes. Carbon dioxide once dissolved in the sea forms the carbonate ion which combines with calcium (not carbonate) to form calcium carbonate (p.12). P.67- the cape of good hope is at the tip of AFrica not South AMerica. And lastly (I have only read to page 80!) the positive charge of the water molecule is on the hydrogen not oxygen (negative on oxygen), and the hydrogens in water don't bind to one another-like charges repel each other , not attract. The hydrogens (+) bind to the oxygens (-) to adjacent molecules!!!!!!!!!! Ugh!!!!!!!!

I have already written a review. I think I may have been sort of mean. Now that I have read the entire book I feel like I should write a new review. I did enjoy the book. The mistakes I refered to in my previous review did not continue throughout the book. I read it to my son at night and he enjoyed it. Overall it was a pretty decent read. So, I've changed my mind.

I bought about 5 books at the same time and this is the 3rd book that I have read. It is full of lots of information but I am finding it a little slow to read. Kind of text book reading. None the less full of useful information regarding the Ocean from the beginning of time! I think it is a good building block for someone like myself trying to delve into the Science of the Ocean.
