Sassi The Ultimate Atlas - The Sea

The Earth is largely covered in water: oceans, lakes and rivers make up 71% of the Earth’s surface, which explains why, when we look at our planet from space, we see it as a big blue ball. When did oceans and seas form? What is the difference between the sea and the ocean? What organisms live in the marine ecosystem?

The box contains 40 question and answer cards, a 64-page atlas, a 500-piece puzzle and 20 special pieces with sea creatures and marine phenomena to place on the puzzle.
