Q: The following article contains an answer for the question: What is the name used when the sea draws back and leaves subtidal areas close to the shore exposed? , can you please find it? A tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea. These events can temporarily lift or lower the surface of the sea in the affected area, usually by a few feet. The potential energy of the displaced seawater is turned into kinetic energy, creating a shallow wave, a tsunami, radiating outwards at a velocity proportional to the square root of the depth of the water and which therefore travels much faster in the open ocean than on a continental shelf. In the deep open sea, tsunamis have wavelengths of around 80 to 300 miles (130 to 480 km), travel at speeds of over 600 miles per hour (970 km/hr) and usually have a height of less than three feet, so they often pass unnoticed at this stage. In contrast, ocean surface waves caused by winds have wavelengths of a few hundred feet, travel at up to 65 miles per hour (105 km/h) and are up to 45 feet (14 metres) high.A trigger event on the continental shelf may cause a local tsunami on the land side and a distant tsunami that travels out across the ocean. The energy of the wave is dissipated only gradually, but is spread out over the wave front, so as the wave radiates away from the source, the front gets longer and the average energy reduces, so distant shores will, on average, be hit by weaker waves. However, as the speed of the wave is controlled by the water depth, it does not travel at the same speed in all directions, and this affects the direction of the wave front - an effect known as refraction - which can focus the strength of the advancing tsunami on some areas and weaken it in others according to undersea topography. As a tsunami moves into shallower water its speed decreases, its wavelength shortens and its amplitude increases enormously, behaving in the same way as a wind-generated wave in shallow water, but on a vastly greater scale. Either the trough or the crest of a tsunami can arrive at the coast first....
A: trough
Question: The following article contains an answer for the question: What is the first name of the person for whom most of his large canvases were completed in his most productive period, from late 1916 to early 1917? , can you please find it? Thomson was largely self-taught. His experiences as a graphic designer with Toronto's Grip Ltd. honed his draughtsmanship. Although he began painting and drawing at an early age, it was only in 1912, when he was well into his thirties, that he began to paint seriously. His first trips to Algonquin Park inspired him to follow the lead of fellow artists in producing oil sketches of natural scenes on small, rectangular panels for easy portability while travelling. Between 1912 and his death in 1917, Thomson produced hundreds of these small sketches, many of which are now considered works in their own right, and are mostly found in the Art Gallery of Ontario in Toronto, the National Gallery of Canada in Ottawa, the McMichael Canadian Art Collection in Kleinburg and the Tom Thomson Art Gallery in Owen Sound.Thomson produced nearly all of his works between 1912 and 1917. Most of his large canvases were completed in his most productive period, from late 1916 to early 1917. The patronage of James MacCallum enabled Thomson's transition from graphic designer to professional painter. Although the Group of Seven was not founded until after his death, his work was sympathetic to that of group members A. Y. Jackson, Frederick Varley, and Arthur Lismer. These artists shared an appreciation for rugged, unkempt natural scenery, and all used broad brush strokes and a liberal application of paint to capture the beauty and colour of the Ontario landscape. Thomson's art also bears some stylistic resemblance to the work of European post-impressionists such as Vincent van Gogh. Other key influences were the Art Nouveau and Arts and Crafts movements of the late nineteenth and early twentieth centuries, styles with which he became familiar while working in the graphic arts.
Answer: Tom
Question: The following article contains an answer for the question: What country can southern elephant seals be seen? , can you please find it? The Catlins coast often hosts New Zealand fur seals and Hooker's sea lions, and occasionally southern elephant seals can be seen. Several species of penguin also nest along the coast, notably the rare yellow-eyed penguin (hoiho), as do other seabirds including mollymawks and Australasian gannets, and the estuaries of the rivers are home to herons, stilts, godwits and oystercatchers. Bitterns and the threatened fernbird (matata) can also occasionally be seen along the reedy riverbanks.In the forests, endangered birds such as the yellowhead (mohua) and kakariki (New Zealand parakeet) occur, as do other birds such as the tui, fantail (piwakawaka), and kereru (New Zealand pigeon). One of New Zealand's only two native species of non-marine mammal, the long-tailed bat, lives in small numbers within the forests, and several species of lizard are also found locally, including the southern forest gecko.Many species of fish, shellfish, and crustaceans frequent both the local rivers and sea, notably crayfish and paua. Nugget Point in the northern Catlins hosts a particularly rich variety of marine wildlife. The establishment of a marine reserve off the coast here, discussed in 1992, 2004 and 2015, has been controversial. Hector's dolphins can often be seen close to the Catlins coast, especially at Porpoise Bay near Waikawa, which is protected as part of the Catlins Coast Marine Mammal Sanctuary, established in 2008. Migratory southern right whales and humpback whales can be spotted along the coastline during winter.
Answer:
New Zealand
