Dog Breeds and facts

The dog is a domesticated form of the wolf, a member of the Canidae family of the order carnivora. The domestic dog has been one of the most widely kept working and companion animals in human history. The dog quickly became ubiquitous across culture across the world, and was extremely valuable to early human settlements. Dogs perform many roles for people, such as hunting, herding, protection, assisting police and military, companionship, and more recently, aiding handicapped individuals. Currently, there are estimated to be 900 million dogs in the world. Over the 15,000 years span that the dog had been domesticated, it diverged into only a handful of landraces, groups of similar animals whose morphology and behaviour have been shaped by environmental factors and functional roles. As the modern understanding of genetics developed, humans began to intentionally breed dogs for a wide range of specific traits. Through this process, the dog has developed into hundreds of varied breeds and

Rivers and facts

A river’s source may be rainfall, a melting snow field or a glacier, a spring, or the overflow of a lake. Streams that flow at a river source are the headwaters and are at the river’s highest elevation. Most river headwaters begin in hills or mountain, but as the river flows downstream, it gains more water from other streams, rivers, springs, added rainfall, and other water sources. The Stages of River All rivers have an upper, middle and lower course. Young River – (The upper course) Middle Aged River – (The middle course) Old River – (The lower course) Uses of Rivers Rivers have always been important for travel, transportation and trade routes. Most settlements were built along major rivers. Rivers are also important for farming because river valleys and plains provide fertile soils. Farmers in dry regions irrigate their Copeland using water carried by irrigation ditches from nearby rivers. Rivers also are an important energy source. During the early industrial era, mills, shops a

Water and facts

Water is continuously moving around the earth and constantly changing its form. It evaporates from land and water bodies and is also produced by all forms of life on Earth. This water vapour moves through the atmosphere, condenses to form clouds and precipitates as rain and snow. In time, the water returns to where it came from, and the process begins all over again. Although water is constantly moving, its total quantity on Earth’s surface is constant.(Water Facts) Water vapour Water vapour is water in its gaseous state-instead of liquid or solid (ice). Water vapour is totally invisible. If you see a cloud, fog, or mist, these are all liquid water, not water vapour. Water vapour is extremely important to the weather and climate. Without vapour out it, there would be no clouds or rain ar snow, since all of these have their source in water vapour. All of the water vapour that evaporates from the surface of the Earth eventually returns as precipitation – rain or snow. Water vapour is als

The shorthaired domestic cat spread across the world from Egypt while long haired cats came later from Turkey and Iran. The domestic cat also spread from India to China and Japan. Ex
