A divide is the elevated boundary separating areas that are drained by different river systems. For this reason, the feature is often called a drainage divide. Water flowing on one side of a divide empties into one body of water, while water flowing on the other side empties into another. Divides range in height from a slight rise in the land to the crest of a mountain range. A divide on the low-lying flood plains of northern Belgium, for example, may rise no higher than a few meters. At the other extreme, the Andes—one of the longest mountain ranges in the world—form a divide in South America. A mountain range that forms a divide is called a dividing range. There are three major types of divides: continental divides, major divides, and minor divides. ContinentalDivides A divide that separates different watersheds of a continent is called a continentaldivide. Because a continent may have more than two watersheds, a continent may have more than one continentaldivide. North America, for instance, has about five continentaldivides. These continentaldivides separate the drainage systems leading to the Pacific Ocean, Arctic Ocean, Atlantic Ocean, Hudson Bay, and Gulf of Mexico. The most familiar continentaldivide in North America separates the watersheds of the Pacific Ocean in the west and the Arctic Ocean, Hudson Bay, Atlantic Ocean, and the Gulf of Mexico in the east. The so-called Great Divide roughly follows the crest of the Rocky Mountains. Major Divides A major divide fo...

Q. What is meant by a water divide? Give an example. A water divide, also known as a drainage divide, is a ridge that divides two drainage basins. On the rugged ground, the split runs along topographical ridges and can take the form of a single dividing range of hills or mountains. The Satpura Range is an example of a water divide that separates the Narmada and Tapti rivers. The rivers in India’s drainage system are classified into two primary groups— • The Himalayan River The Indus, Ganga, and the Brahmaputra are the three major Himalayan rivers. • The Indus Valley System: The river Indus begins near Lake Mansarovar in Tibet. It runs west and reaches India in Jammu and Kashmir’s Ladakh district. • The Ganga River System: The Gangotri Glacier feeds the Bhagirathi, Ganga’s headwaters. The Ganga emerges at Haridwar from the mountains onto the plane. • The Brahmaputra River System: The Brahmaputra River starts in Tibet east of Mansarovar Lake, near the Indus and Sutlej Rivers’ origins. • The Peninsular Rivers • The Tapi Basin: In Madhya Pradesh’s Betul district, the Tapi rises in the Satpura ranges. • The Narmada Basin: In Madhya Pradesh, the Narmada river rises in the Amarkantak hills. • The Godavari Basin: The Godavari is the peninsula’s major river. It originates from the Western Ghats’ foothills in Maharashtra’s Nasik district. • The Mahanadi Basin: In the hills of Chhattisgarh, the Mahanadi rises. After passing through Odisha, it reaches the Bay of Bengal. • The Krishna ...
