Kabul vs Boulder

Informations

Kabul (Pashto: کابل, romanized: Kābəl; Dari: کابل, romanized: Kābol) is the capital and largest city of Afghanistan, situated in the eastern section of the country. It is also a municipality, forming part of the greater Kabul Province, and divided into 22 districts. Based on estimates in 2020, the population of Kabul is 4.222 million, which includes all the significant ethnic groups of Afghanistan. Afghanistan's only city with a population of over 1 million, Kabul serves as its political, cultural and economical center. Rapid urbanization has made Kabul the world's 75th biggest city.Kabul is situated high up in a narrow valley between the Hindu Kush mountains, with an elevation of 1,790 metres (5,873 ft) making it one of the greatest capitals in the world. The city is said to be over 3,500 years old, said since at the time of the Achaemenid Empire. Located at crossroads in Asia - approximately halfway between Istanbul in the west and Hanoi in the east - it's in a strategic location along the trade routes of South and Central Asia, and a key location of the historical Silk Road. It has been part of the Achaemenids followed by the Seleucids, Mauryans, Kushans, Kabul Shahis, Saffarids, Samanids, Ghaznavids, Ghurids, Khwarazmians, Qarlughids, Khaljis, Timurids, Mughals, and Hotaks, until eventually becoming part of the Durrani Empire (also known as the"Afghan Empire") in 1747.

Kabul became the capital of Afghanistan in 1776, during the reign of Timur Shah Durrani, the son of Ahmad Shah Durrani. From the early 19th century, the British occupied the city, but after launching foreign relations, they were forced to withdraw all forces from Afghanistan. The city was occupied by the Soviets in 1979 but they too abandoned it after the 1988 Geneva Accords were signed. A civil war in the 1990s involving various rebel groups destroyed much of the city, leading to many casualties. From late 2001 the city has been continuously rebuilt.Kabul is well known for its gardens, bazaars, and palaces, well known examples being the Gardens of Babur and Darul Aman Palace. It was also formerly a mecca for young western hippies. Despite frequent terrorist attacks in the city, mainly by Taliban insurgents, the city continues to develop and was the fifth largest city in the world as of 2012.

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.
