The Himalayas, or Himalaya is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The Himalayas include the highest mountains in the world, and are known for their soaring heights, steep-sided jagged peaks, valleys, and alpine glaciers, deep river gorges, and a series of elevational belts that display different ecological associations of flora, fauna, and climate .The Himalayas are home to some of the most exotic locations in the world, featuring the highest peaks on Earth, snow-clad landscapes, beautiful meadows, lakes, rivers and valleys.This immense mountain range began to form between 40 and 50 million years ago, when two large landmasses, India and Eurasia, driven by plate movement, collided. Because both these continental landmasses have about the same rock density, one plate could not be subducted under the other.
