Dive into the wild waters of the hydrosphere to explore discoveries about our oceans habitats, life, and zones in this engaging science book. From the abyssal plain to the continental shelf, fifth-grade readers will learn all about underwater land features, tectonic plates, currents and waves, the hydrologic cycle, the oceans effects on climate, and more through this high-interest informational text filled with vibrant photographs. Aligned to the Next Generation Science Standards, a hands-on Think Like a Scientist lab activity and a Your Turn page at the end of the book support STEM Education and provide young scientists with an opportunity to apply what theyve learned in the text. Helpful diagrams and text features, such as a glossary and index, are also included to reinforce content-area literacy and improve close reading.
