Kyiv vs Boulder

Informations

Kyiv or Kiev (Ukrainian: Київ) is the capital and most populous city of Ukraine. It is in north-central Ukraine along the Dnieper River. Its population in July 2015 has been 2,887,974 (though greater estimated numbers have been cited in the media ), making Kyiv the seventh-most populous city in Europe.Kyiv is an important industrial, scientific, educational and cultural center of Eastern Europe. It is home to many high-tech businesses, higher education institutions, and historical landmarks. The town has an extensive system of public transport and infrastructure, including the Kyiv Metro. The city's name is said to derive from the name of Kyi, one of its four legendary creators. During its history, Kyiv, one of the oldest cities in Eastern Europe, passed through several phases of prominence and obscurity. The city probably existed as a commercial centre as early as the 5th century. A Slavic settlement on the wonderful trade route between Scandinavia and Constantinople, Kyiv was a tributary of the Khazars, until its capture by the Varangians (Vikings) in the mid-9th century. Under Varangian rule, the town became a capital of the Kievan Rus', the first East Slavic state. Completely destroyed during the Mongol invasions in 1240, the city lost most of its influence for the centuries to come. It was a provincial capital of marginal value in the outskirts of the lands controlled by its powerful neighbours, first Lithuania, then Poland and Russia.

The city prospered again during the Russian Empire's Industrial Revolution in the late 19th century. In 1918, following the Ukrainian People's Republic declared independence from Soviet Russia, Kyiv became its capital. From 1921 onwards Kyiv was a town of Soviet Ukraine, which was proclaimed by the Red Army, and, from 1934, Kyiv was its capital. The town was almost completely ruined during World War II but quickly recovered from the postwar years, remaining Soviet Union's third-largest city. After the collapse of the Soviet Union and Ukrainian independence in 1991, Kyiv remained Ukraine's capital and experienced a steady influx of cultural migrants from different regions of the country. During the country's transformation into a market economy and electoral democracy, Kyiv has continued to be Ukraine's biggest and wealthiest city. Its armament-dependent industrial output fell after the Soviet collapse, adversely affecting science and technology, but new sectors of the economy such as services and finance facilitated Kyiv's increase in salaries and investment, as well as providing continuous funding for the development of housing and urban infrastructure. Kyiv emerged as the most pro-Western area of Ukraine; parties advocating tighter integration with the European Union dominate during elections.

In geology, a boulder is a rock fragment with size greater than 256 millimetres (10.1 in) in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks (American English) or stones (In British English a rock is larger than a boulder). The word boulder is short for boulder stone, from Middle English bulderston or Swedish bullersten.In places covered by ice sheets during Ice Ages, such as Scandinavia, northern North America, and Siberia, glacial erratics are common. Erratics are boulders picked up by ice sheets during their advance, and deposited when they melt.

They are called "erratic" because they typically are of a different rock type than the bedrock on which they are deposited. One of them is used as the pedestal of the Bronze Horseman in Saint Petersburg, Russia. Some noted rock formations involve giant boulders exposed by erosion, such as the Devil's Marbles in Australia's Northern Territory, the Horeke basalts in New Zealand, where an entire valley contains only boulders, and The Baths on the island of Virgin Gorda in the British Virgin Islands. Boulder-sized clasts are found in some sedimentary rocks, such as coarse conglomerate and boulder clay. The climbing of large boulders is called bouldering.
