Half of our planet is covered by the ocean, yet we`ve only explored 5 percent of this vast underwater realm. Originally published in Portugal, & awarded a highly coveted Bologna Ragazzi Mention by the Bologna Book Fair, this visually compelling miscellany offers readers a tsunami of aquatic facts. Which ocean is the largest? Who was the first explorer to sail around the world? Is the ocean truly blue? Beautifully designed & rich with information, Ocean will satisfy enthusiastic readers who enjoy taking a deep dive into a subject as well as more reluctant readers who prefer to dip in & out of a book.
