A mountain might be thousands of feet high, but it can still grow taller or shorter each year. This classic picture book explores how mountains are made-including how Mount Everest grew from a flat plain under an ocean to become 29,028 feet tall! Now rebranded with a new cover look, this book features simple activities and fascinating cross-sections of the earth's moving crust that clearly explain plate tectonics. Both text and artwork were vetted for accuracy by an expert in the field. This is a Level 2 Let's-Read-and-Find-Out Science title, which means the book explores more challenging concepts for children in the primary grades and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards. Let's-Read-and-Find-Out Science is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.
