These mountains are young compared to other ranges. They began forming about 60 to 65 million years ago. By comparison, the Appalachian range is 250 to 300 million years old. Tectonic plates, which are huge slabs of rock on which continents sit, often bump together. They cause earthquakes and push up mountains. The tectonic plate on which India sits is pressing into the giant landmass of Eurasia. This pushes up the landmass, forming massive wrinkles. These wrinkles are the foundation of the Himalayas. The plate is still pushing up against Asia. So the Himalayan Mountains are still growing at about one inch every five years. The land at the top of these mountains was once a part of the ocean seabed. Fossils of sea creatures are still stuck in the rocks at the top of these mountains. Mount Everest is the tallest mountain in the world at 29,028 feet. It is in the Himalayas, as is K2 at 28,250 feet. There are six other mountains in the range over 26,500 feet. All of them are still growing. These mountains are often called the “Rooftop of the World.” The word “Himalaya” comes from a word meaning “house of snow.” The range stretches more than 1,500 miles through many countries in central Asia.
