Please answer this: The following article contains an answer for the question: What are of interest as a potential energy source? , can you please find it? The seabed contains enormous reserves of minerals which can be exploited by dredging. This has advantages over land-based mining in that equipment can be built at specialised shipyards and infrastructure costs are lower. Disadvantages include problems caused by waves and tides, the tendency for excavations to silt up and the washing away of spoil heaps. There is a risk of coastal erosion and environmental damage. Seafloor massive sulphide deposits are potential sources of silver, gold, copper, lead and zinc and trace metals since their discovery in the 1960s. They form when geothermally heated water is emitted from deep sea hydrothermal vents known as "black smokers". The ores are of high quality but prohibitively costly to extract. Small scale mining of the deep sea floor is being developed off the coast of Papua New Guinea using robotic techniques, but the obstacles are formidable.There are large deposits of petroleum, as oil and natural gas, in rocks beneath the seabed. Offshore platforms and drilling rigs extract the oil or gas and store it for transport to land. Offshore oil and gas production can be difficult due to the remote, harsh environment. Drilling for oil in the sea has environmental impacts. Animals may be disorientated by seismic waves used to locate deposits, probably causing the beaching of whales. Toxic substances such as mercury, lead and arsenic may be released. The infrastructure may cause damage, and oil may be spilt.Large quantities of methane clathrate exist on the seabed and in ocean sediment at a temperature of around 2 C (36 F) and these are of interest as a potential energy source. Some estimates put the amount available at between one and 5 million cubic kilometres (0.24 to 1.2 million cubic miles). Also on the seabed are manganese nodules formed of layers of iron, manganese and other hydroxides around a core. In the Pacific these may cover up to 30 percent of the deep ocean floor. The minerals precipitate from seawater and grow very slowly. Their commercial extraction for...

Answer: Large quantities of methane clathrate

Please answer this: The following article contains an answer for the question: What is the last name of the person whose decision to enter the competition for the Prix de Rome again was puzzling to many in musical circles? , can you please find it? In 1861 Saint-Saens accepted his only post as a teacher, at the Ecole de Musique Classique et Religieuse, Paris, which Louis Niedermeyer had established in 1853 to train first-rate organists and choirmasters for the churches of France. Niedermeyer himself was professor of piano; when he died in March 1861, Saint-Saens was appointed to take charge of piano studies. He scandalised some of his more austere colleagues by introducing his students to contemporary music, including that of Schumann, Liszt and Wagner. His best-known pupil, Gabriel Faure, recalled in old age: After allowing the lessons to run over, he would go to the piano and reveal to us those works of the masters from which the rigorous classical nature of our programme of study kept us at a distance and who, moreover, in those far-off years, were scarcely known. ... At the time I was 15 or 16, and from this time dates the almost filial attachment ... the immense admiration, the unceasing gratitude I [have] had for him, throughout my life. Saint-Saens further enlivened the academic regime by writing, and composing incidental music for, a one-act farce performed by the students (including Andre Messager). He conceived his best-known piece, The Carnival of the Animals, with his students in mind, but did not finish composing it until 1886, more than twenty years after he left the Niedermeyer school.In 1864 Saint-Saens caused some surprise by competing a second time for the Prix de Rome. Many in musical circles were puzzled by his decision to enter the competition again, now that he was establishing a reputation as a soloist and composer. He was once more unsuccessful. Berlioz, one of the judges, wrote: We gave the Prix de Rome the other day to a young man who wasn't expecting to win it and who went almost mad with joy. We were all expecting the prize to go to Camille Saint-Saens, who had the strange notion of competing. I confess I was sorry to vote against a man who is truly a great artist and one who is already well known, practically a celebrity....

Please answer this: The following article contains an answer for the question: What was the name of the song that was on the reverse side of "Blue Moon of Kentuckey"? , can you please find it? The session, held the evening of July 5, proved entirely unfruitful until late in the night. As they were about to abort and go home, Presley took his guitar and launched into a 1946 blues number, Arthur Crudup's "That's All Right". Moore recalled, "All of a sudden, Elvis just started singing this song, jumping around and acting the fool, and then Bill picked up his bass, and he started acting the fool, too, and I started playing with them. Sam, I think, had the door to the control booth open ... he stuck his head out and said, 'What are you doing?' And we said, 'We don't know.' 'Well, back up,' he said, 'try to find a place to start, and do it again.'" Phillips quickly began taping; this was the sound he had been looking for. Three days later, popular Memphis DJ Dewey Phillips played "That's All Right" on his Red, Hot, and Blue show. Listeners began phoning in, eager to find out who the singer really was. The interest was such that Phillips played the record repeatedly during the remaining two hours of his show. Interviewing Presley on air, Phillips asked him what high school he attended in order to clarify his color for the many callers who had assumed that he was black. During the next few days, the trio recorded a bluegrass number, Bill Monroe's "Blue Moon of Kentucky", again in a distinctive style and employing a jury rigged echo effect that Sam Phillips dubbed "slapback". A single was pressed with "That's All Right" on the A side and "Blue Moon of Kentucky" on the reverse.
