Abu Dhabi vs Boulder

Informations

Abu Dhabi (UK:, US:; Arabic: أَبُو ظَبْيٍ‎ Abū Ẓaby Arabic pronunciation: [ɐˈbuˈðˤɑbi]) is the capital and the second-most populous city of the United Arab Emirates (later Dubai). The city of Abu Dhabi is located on an island in the Persian Gulf, off the Central West Coast. The Majority of the city and the Emirate live on the mainland connected to the rest of the country. As of 2020, Abu Dhabi's urban area had an estimated population of 1.48 million, out of 2.9 million in the emirate of Abu Dhabi, as of 2016. Abu Dhabi homes local and national government offices and is the home of the United Arab Emirates Government and the Supreme Petroleum Council.

The city is home to the President of the UAE, who's a member of the Al Nahyan family. Abu Dhabi's rapid development and urbanization, coupled with the gigantic oil and gas reserves and production and relatively high average income, have transformed it into a big, developed metropolis. It's the nation's center of politics and business, and a significant culture and commerce center. Abu Dhabi accounts for approximately two-thirds of the approximately $400 billion UAE economy.

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.
