Mount Everest, Earth's tallest mountain over sea level, formed about 40 million to 50 million years ago when prehistoric continents split and collided. This process was made possible by the movement of Earth's tectonic plates. Readers will learn more about how the movement of these tectonic plates helped form the Himalayas, including Everest. Breathtaking photographs provide readers with visual correlations to the narrative, while fact boxes and sidebars supplement the main text.
