Falls of the world

niagara-falls

Waterfalls are most 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 rate of retreat for a waterfall can be as high as one and half meters per year.

Amazing Cave

burger-Otok-krizna-jama

 A cave or cavern is a natural underground space large enough for a human to enter. Some people[who?] suggest that the term cave should only apply to natural cavities some part of which is in total darkness; however, in popular usage, the term includes smaller spaces like sea caves, rock shelters, and grottos.

Speleology is the science of exploration and study of all aspects of caves and the environment which surrounds the caves. Exploring a cave for recreation or science may be called caving, potholing, or, in Canada and the United States, spelunking.

Tornado

tornado

    A tornado (often referred to as a twister or, erroneously, a cyclone) is a violent, dangerous, rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Tornadoes come in many shapes and sizes, but are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust. Most tornadoes have wind speeds less than 110 miles per hour (177 km/h), are approximately 250 feet (80 m) across, and travel a few miles (several kilometers) before dissipating. The most extreme can attain wind speeds of more than 300 mph (480 km/h), stretch more than two miles (3 km) across, and stay on the ground for dozens of miles (more than 100 km).

Chocolate Hills of the Phillippenes

chocolate-hills

The Chocolate Hills are an unusual geological formation in Bohol, Philippines. According to the latest accurate survey done,there are 1,776 hills spread over an area of more than 50 square kilometres. They are covered in green grass that turns brown during the dry season, hence the name.

The Chocolate Hills are a famous tourist attraction of Bohol. They are featured in the provincial flag and seal to symbolize the abundance of natural attractions in the province. They are in the Philippine Tourism Authority's list of tourist destinations in the Philippines;they have been declared the country's third National Geological Monument and proposed for inclusion in the UNESCO World Heritage List.

Amazing Tourist and Trucking place in China to visit Shanxi

shanxi

Shanxi province is a beautiful place  in China. It looks fantastic and truly amazing on these photos. Shanxi Province got its name due to its location to the west of Taihang Mountain. Shanxi neighbored on Hebei, Henan, Shaanxi and Inner Mongolia & Autonomous Region. It is located to the east of the Yellow River, and is also known as Hedong. Shanxi belonged to Jin State in Spring and Autumn Period, so it is abbreviated in Jin. Shanxi occupies an area of 156,000 square kilometers and has a population of over 32 million, including its minority ethnic population. Its capital is Taiyuan City.

Amazing wetland

the-largest-wetland-system-in-the-united-states

A wetland is an area of land whose soil is saturated with moisture either permanently or seasonally. Such areas may also be covered partially or completely by shallow pools of water.
Wetlands include swamps, marshes, and bogs, among others.The water found in wetlands can be saltwater, freshwater, or brackish. The world's largest wetland is the Pantanal which straddles Brazil, Bolivia and Paraguay in South America.

Amazing tigers

bengal-tiger

The tiger (Panthera tigris), a member of the Felidae family, is the largest of the four "big cats" in the genus Panthera. Native to much of eastern and southern Asia, the tiger is an apex predator and an obligate carnivore. Reaching up to 3.3 metres (11 ft) in total length, weighing up to 300 kilograms (660 pounds), and having canines up to 4 inches long, the larger tiger subspecies are comparable in size to the biggest extinct felids.Aside from their great bulk and power, their most recognisable feature is a pattern of dark vertical stripes that overlays near-white to reddish-orange fur, with lighter underparts. The most numerous tiger subspecies is the Bengal tiger while the largest is the Siberian tiger.

Horse History

quarter-horse

The horse (Equus ferus caballus) is a hooved (ungulate) mammal, a subspecies of the family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature into the large, single-toed animal of today. Humans began to domesticate horses around 4000 BC, and their domestication is believed to have been widespread by 3000 BC. Although most horses today are domesticated, there are still endangered populations of the Przewalski's Horse, the only remaining true wild horse, as well as more common populations of feral horses which live in the wild but are descended from domesticated ancestors. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behaviour.

Amazon Tree Houses, Beautiful

According to the description that comes with this very interesting series of images, they depict a village located in Afghanistan. The images show a small town, complete with dwellings, stairways, paths and walk bridges, that has apparently been carved out of strange cone-shaped natural formations nestled on a hillside.

Amazing deserts

libya-tadrart-acacus-luca-galuzzi

 Deserts are part of a wide classification of regions that, on an average annual basis, have a moisture deficit (i.e. they can potentially lose more than is received). Deserts are located where vegetation cover is sparse to almost nonexistent.Deserts take up about one fifth (20%) of the Earth's land surface.Hot deserts usually have a large diurnal and seasonal temperature range, with high daytime temperatures, and low nighttime temperatures (due to extremely low humidity). In hot deserts the temperature in the daytime can reach 45 °C/113 °F or higher in the summer, and dip to 0 °C/32 °F or lower at nighttime in the winter. Water vapor in the atmosphere acts to trap infrared radiation from both the sun and the ground, and dry desert air is incapable of blocking sunlight during the day or trapping heat during the night. Thus, during daylight most of the sun's heat reaches the ground, and as soon as the sun sets the desert cools quickly by radiating its heat into space. Urban areas in deserts lack large (more than 14 °C/25 °F) daily temperature variations, partially due to the urban heat island effect.

Amazing snakes

coast-garter-snake

 Snakes are elongate, legless, carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears. Like all squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with many more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.

Amazing lions

hansome-lion

 The lion (Panthera leo) is one of the four big cats in the genus Panthera, and a member of the family Felidae. With some males exceeding 250 kg (550 lb) in weight,it is the second-largest living cat after the tiger. Wild lions currently exist in Sub-Saharan Africa and in Asia with a critically endangered remnant population in Gir Forest National Park in India, having disappeared from North Africa and Southwest Asia in historic times. Until the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans. They were found in most of Africa, across Eurasia from western Europe to India, and in the Americas from the Yukon to Peru.

Amazing Bird migration

                                                          Northern_Pintail                   

Bird migration is the regular seasonal journey undertaken by many species of birds. Bird movements include those made in response to changes in food availability, habitat or weather. Sometimes, journeys are not termed "true migration" because they are irregular (nomadism, invasions, irruptions) or in only one direction (dispersal,

movement of young away from natal area). Migration is marked by its annual seasonality. In contrast, birds that are non-migratory are said to be resident or sedentary. Approximately 1800 of world's 10,000 bird species are long-distance migrants.

Amazing Bird of prey

   Bald eagle

Birds of prey are birds that hunt for food primarily on the wing, using their keen senses, especially vision. They are defined as birds that primarily hunt vertebrates, including other birds. Their talons and beaks tend to be relatively large, powerful and adapted for tearing and/or piercing flesh. In most cases, the females are considerably larger than the males. The term "raptor" is derived from the Latin word "rapere" (meaning to seize or take by force) and may refer informally to all birds of prey, or specifically to the diurnal group. Because of their overall large size and predatory lifestyle, they face distinct conservation concerns.
