Geology of Dasam Falls in Ranchi district of Jharkhand State, India.

 The Dassam Fall is a natural cascade across the Kanchi River. by Dr. Nitish Priyadarshi Geologist A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Waterfalls are also called cascades. Waterfalls are commonly formed when a river is young. At these times the channel is often narrow and deep. When the river courses over resistant bedrock, erosion happens slowly, while downstream the erosion occurs more rapidly. As the watercourse increases its velocity at the edge of the waterfall, it plucks material from the riverbed. Whirlpools created in the turbulence as well as sand and stones carried by the watercourse increase the erosion capacity. This causes the waterfall to carve deeper into the bed and to recede upstream. Often over time, the waterfall will recede back to form a canyon or gorge downstream as it recedes upstream, and it will carve deeper into the ridge above it. The process of erosion, the wearing away of earth, plays an im...

Pollution is the the big threat. by Dr. Nitish Priyadarshi nitish.priyadarshi@gmail.com Physiography : The spatial extent of Jharkhand State is approximately 21° 55’ to 25° 35’ North Latitude and 83° 20’ to 88° 02’ East Longitude. The state is land locked and it shares its boundary with Orissa on the southeast, Chattisgarh on the southwest, Bihar on the north, West Bengal on the east and Uttar Pradesh on the northwest. It comprises of the Chotanagpur Plateau, which forms a part of Deccan bio-geographic province. It is a hilly undulating plateau characterized by predominantly tropical forests and tribal settlements.

Why vegetarian animals are fat?

Theory begins some 50 million years back. By Dr. Nitish Priyadarshi. One of my friends suggested me to become non-vegetarian. He gave the interesting example about the benefit of becoming non- vegetarian. He said that all non-vegetarian animals like tiger, cheetah, wolfs are slim compared to vegetarian animals like buffalo, elephant, zebras etc. I started searching the mystery of why vegetarian animals are so fat? Some theories are hidden in pages of time million years back. Why did some prehistoric animals get so big in the first place? No one knows for sure, but there are lots of theories. One theory begins some 50 million years back. The past 50 million years appear to have been a time of progressive deterioration. On every vegetated continent, grasses and small hard leaves widened their domain. While certain herbivores accommodated to the new foliage- and evolved the art of eating coarse, fibrous fodder-other species, committed to Eocene and Oligocene ways, died. In many animal...
