Answers
Explanation:
1.Known in the past as the premiere Honeymoon destination, this geological wonder is not only one of most popular tourist attractions in the state of New York, but also functions as one of the major power providers to the state itself. Comprised of three waterfalls — American Falls, Horseshoe Falls and Bridal Veil Falls — Niagara Falls water stems from the upper Great Lakes and the river is estimated to be 12,000 years old. The wonder of the falls has intrigued many and has prompted daredevils to “conquer” the falls in various contraptions from wooden barrels to rubber balls.
2.The Library of Congress reports that mass hysteria branded Halley's Comet "the evil eye of the sky" in 1910, prompting the sales of anti-comet pills and gas masks in the event that it hit the planet and triggered an apocalyptic explosion. It harmlessly passed between Earth and the sun in May of that year.
A "periodic" comet that appears about every 75 years, it passed by again in 1986 and is slated to return in 2061.
3.For over 200 years, ever since Vice President Aaron Burr's daughter Theodosia (lovely name) and her new husband 'mooned there in 1802, Niagara Falls has called itself the “Honeymoon Capital of the World.” For most of the 19th and 20th centuries, it was a place that many American newlyweds could easily and cheaply
4.The first person to ride over the falls and live to tell the tale was not a famous daredevil or performer, but a widowed teacher named Annie Edson Taylor.
5.If the temperature is cold enough, ocean water does freeze. The polar ice cap at earth's North Pole is a giant slab of frozen ocean water. At earth's South Pole, the land mass constituting Antarctica complicates the situation, so most of the ice there is compacted snow. Over cold regions such as Antarctica, Greenland, and Canada, the fresh water in the air freezes to snow and falls onto the land without a melting season to get rid of it. Over time, this snow builds up and compacts into an ice mass known as a glacier. Gravity slowly pulls the glacier downhill until it reaches out onto the ocean, forming an ice shelf. The ocean-bound edge of the ice shelf slowly crumbles into icebergs which float off on their own path. For this reason, glaciers, ice shelves, and icebergs are all thick sheets of frozen fresh water and not frozen ocean water. In contrast, when ocean water freezes, it forms a thin flat layer known as sea ice or pack ice. Sea ice has long been the enemy of ships seeking an open route through cold waters, but modern ice breaker ships have no problem breaking a path through the fields of frozen ocean.
