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? This fun-filled set includes so many interesting facts about the sea and its inhabitants explained in an intuitive way supported by fun interactive activities. This set includes a 500 piece puzzle with 20 special 3D pieces, 64 page Atlas, and 40 quiz cards with all the answers to be found in the Atlas. FSC Certified. Age: 6+
