river white
We refer to rivers as the arteries of any country. No living organism can live without water and rivers are the most important source of water. Almost all the early civilizations sprang up on the river banks.
It is because, from ancient times, people realized the fertility of the river valleys. Thus, they began to settle down there and cultivate the fertile valleys. Moreover, rivers originate from mountains which carry down rock, sand and soil from them.
Then they enter plains and water keeps moving slowly from the mountainsides. As a result, they deposit fertile soil. When the river overflows, this fertile soil deposits on the banks of rivers. Thus, bringing fresh fertile soil constantly to the fields.
Most importantly, rivers help in agriculture. In fact, a lot of farmers depend on rivers for agricultural purposes. Rivers have the ability to turn deserts into productive farms. Further, we can use them for constructing dams as well.
Further, rivers also are important highways. That is to say, they offer the cheapest method of transport. Before road and railways, rivers were essential means of transportation and communication.
In addition, rivers bring minerals down from hills and mountains. We construct damns across the river for generating hydel power and also preserve the wildlife. Further, they also come in use for encouraging tourism and developing fisheries.

Birds (Aves) are a group o endothermic vertebrates, characterised bi feathers, tuithless beakit jaws, the layin o haurd-shelled eggs, a heich metabolic rate, a fower-chaumbered hert, and a lichtweicht bit pure tough skelet. Birds bide warldwide and range in size fae the 5 cm (2 in) bee hummingbird tae the 2.75 m (9 ft) ostrich. Thay rank as the cless o tetrapods wi the maist livin species, at aboot ten thoosand, wi mair nor hauf o thae bein passerines, whiles kent as perching birds or, less richtly, as songbirds.
The fossil record indicates that birds are the lest surviving dinosaurs, termed avian dinosaurs, haed evolved frae feathered ancestors inwith the theropod group o saurischian dinosaurs. True birds erest appeared while the Cretaceous feck, aroond 100 million years aby. DNA-evident shaws that birds diversified dramatically aroond the time o the cretaceous–paleogene extinction event that kilt aff a ither dinosaurs. Birds in Sooth America owercome this event and syne migrated tae ither bits o the warld via multiple laund brigs, while diversifying while periods o global cooling. primitive bird-lik dinosaurs that lie ootdoors cless aves proper, in the broader group avialae, hae bin fun datin back tae the mid-Jurassic period. Mony o thae earlie "stem-birds", sic as archaeopteryx, wur nae yit capable o fully powered flight, and mony keepit primitive characteristics like tuithie jaws in steid o beaks, and lang bony tails.
