How Mountains Are Made

This classic explores how mountains are made, including how Mount Everest grew from a flat plain under an ocean to become 29,028 feet tall! Even though Mount Everest measures 29,028 feet high, it may be growing about two inches a year. A mountain might be thousands of feet high, but it can still grow taller or shorter each year. Mountains are created when the huge plates that make up the earth’s outer shell very slowly pull and push against one another.
