50 Incredible Facts About Oceans has the same clear layout and explores the oceans but provides a different selection of facts from the first book, so it would be great for readers who have a keen interest in oceans. Looking more at the oceans specifically, as opposed to the animals living in them, this book has facts about the difference between oceans and seas, their currents, and why they’re so important for capturing CO2 and supplying our oxygen. The facts in this book are slightly more technical, a step up from the first book, and may appeal to readers with a more scientific interest in the oceans or are further into exploring their interest in the topic. Even though the facts are a bit more technical, they are still presented in clear, and easy to understand language which makes the book accessible to a wide range of ages. This book once again ends with a focus on what humans are doing to damage the oceans and the negative impact of pollution and excess CO2.
