Study Notes
Water Cycle
- The water cycle shows the continuous movement of water within the Earth and atmosphere.
- Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
- Water in different phases moves through the atmosphere (transportation), flows across land (runoff), into the ground (infiltration and percolation), and through the ground (groundwater).
- Groundwater moves into plants (plant uptake) and evaporates from plants into the atmosphere (transpiration).
- Solid ice and snow can turn directly into gas (sublimation) and water vapor becomes solid (deposition).
The Himalayas
- The Himalayas are a towering chain of mountains that stretch across the northern part of the Indian subcontinent, forming a natural boundary between India, China, Nepal, Bhutan, and Pakistan.
- The range is the highest and youngest in the world, with its origins tracing back to about 70 million years ago.
- The Himalayas are a complex system of mountain ranges, with the main chain, the Himalaya proper, being the highest and most extensive.
- The range includes the world's highest mountain, Mount Everest (8,848 meters), and the second-highest, K2 (8,611 meters), both located on the border between Pakistan and China.
- The Himalayas contain 14 peaks that exceed 8,000 meters, often referred to as the "eight-thousanders."
Geography and Landscape
- The Himalayas cover an area of about 2,400,000 square kilometers, with the length of the range exceeding 2,400 kilometers.
- The range is divided into three sections: the Himachal Himalaya, the Central Himalaya, and the Eastern Himalaya.
- The Himalayas are home to glaciers, rivers, forests, and rich biodiversity.
Climate and Ecosystem
- The Himalayas are characterized by a diverse climate, ranging from the warm subtropical climate in the foothills to the arctic-like conditions at the higher elevations.
- The cold desert climate of the Tibetan Plateau influences the climate of the Himalayas, particularly in regions like Ladakh and Zanskar.
- The Himalayas host a wide array of flora and fauna, including endemic species like the snow leopard, takin, and Himalayan tahr.
Significance and Challenges
- The Himalayas have immense significance for the countries that share their borders, being a source of several major rivers, including the Ganges, Brahmaputra, and Yangtze.
- The range serves as a traditional trade route between South Asia and China.
- However, the Himalayas are facing numerous challenges, including glacial melting, deforestation, and pollution from mining and industrial activities.
