Act as an interpreter. Кто первым начал изучать снежинки?Кто первым начал изучать снежинки? — Возможно, первые описания снежинок были сделаны в Швеции в 1555. Их назвали шестиугольными ледяными кристаллами. И только когда был изобретен микроскоп, появились дальнейшие исследования форм снежинок. Откуда произошло слово "кристалл"? — Это древнегреческое слово "криллос", означающее "мороз".
Везде ли на Земле выпадает снег? Есть ли территории, где снег никогда не выпадает? — Даже в некоторых местах на экваторе выпадает снег. С другой стороны, в довольно отдаленных от экватора районах, там, где можно ожидать снег, его никогда не было. Известно, что снежинки бывают чрезвычайно разнообразны по форме. А кто-нибудь пытался подсчитать, сколько их форм существует? — Вильсон Бентли, фермер из Вермонта, сфотографировал огромное количество снежинок. Более 5000 самых лучших снимков были опубликованы. Л как возникают подводные снегопады? — Иногда снежинки образуются в холодной воде при смене температур. Поднимаясь вверх, они могут столкнуться с замерзшей поверхностью реки. Text3 The area in northwestern Wyoming known today as Yellowstone National Park was first seen by trappers exploring the area in 1830s and 1840s. They took to the East with them stories about an amazing area full of steaming geysers, bubbling mud, and a boiling underground river. But no one believed such incredible tales. It was not until 1870 that an exploring party was sent out the trappers' reports. Perhaps the most amazing sight was a geyser named "Old Faithful". And for a very good reason the geyser faithfully sent a fountain of hot water and steam into the air every hour, for a show of about four or five minutes. Geysers, however represent only 200 of more than 10,000 hot water creations in Yellowstone National Park. In some places, the muddy-coloured ground literally bubbles; in other places the water collects into steaming pools. What then, makes Old Faithful so special? Mainly, its punctuality, which no other geyser seems to have. Since it was first studied in 1870, Old Faithful has not once missed giving its hourly performance. Another interesting geyser in Yellowstone is "Giantess". It shoots up a fountain that falls back into a cone-shaped crater. Because of its shape, it looks more like a volcano than a crater. The cone shape glistens with the mineral deposits that pile up on it. These deposits leave interesting shapes behind once the water is back underground preparing for another explosion. The silica and lime carbonate in the deposits make some geysers look like castles. Others seem to have towers that give them a magical quality. South Island in New Zealand has also some geysers, but not as many as Yellowstone. A more interesting show of geysers appears in Iceland, whose most famous fountain, Geysir, gave its name to all geysers. But the unusual thing about Iceland's geysers is that they form a ring. Who knows — may be the underground river there is ring-shaped. And even though it is in Iceland, the underground rocks the river touches are still as hot as those under Yellowstone!
