Did you know that the tallest mountain on Earth, Mount Everest, continues to grow at a rate of about 0.16 inches (4 millimeters) per year? This growth is due to the Indian tectonic plate pushing against the Eurasian plate, causing the Himalayan mountain range to rise. While 0.16 inches may not seem like much, over millions of years, it has resulted in the creation of some of the highest peaks in the world.
