Nurmijärvi vs Boulder

Informations

Nurmijärvi (Finnish pronunciation: [ˈnurmiˌjærʋi]) is the most populated rural municipality of Finland, located 37 kilometres (23 mi) north of the capital Helsinki. The neighboring municipalities of Nurmijärvi are Espoo, Vantaa, Tuusula, Hyvinkää and Vihti, and it is part of the Greater Helsinki. The population of the municipality is 43,403 inhabitants. In recent decades, it has been one of the fastest growing municipalities in the Greater Helsinki and also in whole Finland in terms of population; even the 2020 COVID-19 pandemic hasn't shown a slowdown in growth of population.The close proximity to Helsinki has led to a considerable growth of the major villages such as Klaukkala, Rajamäki and Röykkä. Klaukkala is the biggest built-up area of Nurmijärvi, which nowadays is considered a dormitory town of Helsinki.

The church village (Kirkonkylä) is the administrative centre of the municipality, although the clear emphasis on population growth is in Klaukkala. Nurmijärvi literally means "lawn lake" although the lake that gave the municipality its name was drained in the early 20th century and is now nothing more than some flat fields near the village centre. Nurmijärvi is one of three municipalities in the Uusimaa region that do not have a Swedish name; the others are Askola and Mäntsälä. Matti Vanhanen, former Prime Minister of Finland and current finance minister, lives in Lepsämä in Nurmijärvi.

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.
