Ithaca vs Boulder

Informations

Ithaca, Ithaki or Ithaka (; Greek: Ιθάκη, Ithaki [iˈθaci]; Ancient Greek: Ἰθάκη, Ithakē [i.tʰá.kɛː]) is a Greek island located in the Ionian Sea, off the northeast coast of Kefalonia and to the west of continental Greece. Ithaca's main island has an area of 96 square kilometres (37 sq mi) and had a population in 2011 of 3,231. It is the second-smallest of seven main Ionian Islands, after Paxi.

Ithaca is a separate regional unit of the Ionian Islands region, and the only municipality of the regional unit. The capital is Vathy (or Vathi).Modern Ithaca is generally identified with Homer's Ithaca, the home of Odysseus, whose delayed return to the island is the plot of the classical Greek tale the Odyssey.

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.
