Small streams which flow from different directions usually come together to form the main river body.  This river drains into a larger water body like a lake, sea, or ocean. The area which is drained by a single river system is termed a drainage basin .  An elevated physical structure like a mountain or an upland sometimes separates two drainage basins. This physical feature is called the water divide.  Important Drainage Systems of India The drainage systems in India are dominated by b...

Topics to be covered - 1. Water 2. Fresh water. 3. Water scarcity 4. Causes and types. 5. Dams 6. Advantages and disadvantage 7. Rainwater harvesting 8. Old and modern methods Water Three-fourth of the earth’s surface is covered with water but only a small proportion of it accounts for freshwater, that can be put to use. Water is a renewable resource. Fresh water: 96.5 per cent of the total volume of world’s water is estimated to exist as oceans and only 2.5 per cent exists as fresh water. 70 per cent of the fresh water occurs as ice sheets and glaciers in Antarctica, Greenland and the mountainous regions of the world. Less than 30 per cent is stored as groundwater in the world’s acquirers. Fresh water is mainly obtained from surface run off and ground water. This is continually being renewed and recharged through the hydrological cycle. All the water moves within the hydrological cycle making water a renewable resource. Three fresh water sources are: Precipitation—from rainfall; Surfa...

Roopkund  (locally known as  Mystery Lake  or  Skeletons Lake ) . It  is a high altitude glacial lake in the Uttarakhand state of India. It lies in the lap of Trishul massif. Located in the Himalayas the area around the lake is uninhabited and is roughly at an altitude of 5,020 metres (16,470 ft),surrounded by rock-strewn glaciers and snow-clad mountains. Roopkund is a popular trekking destination.The size of the lake varies substantially, but it is seldom more than 40 metres in diameter (1000 to 1500 square metres in area), and is frozen in the winter. Roopkund Lake, locally known as “Mystery Lake”. More recently, the Himalayan lake has also been called “Skeleton Lake”. This name is not without reason: the edges of the lake are literally littered with hundreds of human skeletons. Since my school days I had a interested in knowing the truth behind this lake,I Google from many sources and collected...

  Flora and Fauna in India Biodiversity includes wildlife, cultivated species and different types of life found on earth.They are linked in a system through multiple network of interdependence. For example : e.g. eagle depends on snake, snake on frog, frog on butterfly, butterfly on flowers of plants and plants on sun. We humans are also dependent on the system for our existence. e.g. we depends on trees for fresh oxygen, we depends on river for drinking water, we depend on soil that produces our food. The forest and tree cover in the country is 23.81 % of the total geographical area out of which dense forests covers 12.24%, open forests covers 8.99% and mangrove forests covers 0.14%. Forest Type Covers (Percentage) Dense forest 12.24 % [increased by 10,098 sq km since 1997] Open forest 8.99 % Mangrove 0.14 %   Classification of Existing plants and animal species –  1.Normal Species –  These are the Species whose population levels are considered to be   nor...
