Problem: Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection.

Question: "What can the motion of convection be compared to?"

Answer: "An enormous rock"
Answer: no

Problem: Among the early blows struck for independence was a rebellion in the town of Olhao. On 16 June 1808, the townsfolkarmed with little more than ancient swords, spears, and stonesattacked and captured the local French garrison. It's said that a party of local men then set sail from Olhao all the way to Brazil, without maps or navigational aids, to tell the king of the insurrection. The real battle, however, was waged under the leadership of the Duke of Wellington, whose coalition forces expelled the French after two years of bitter fighting. The war left Portugal further weakened, and in 1822 its major empire outpost, Brazil, declared independence. At the same time, a dispute over the crown continually raged between Pedro IV, the absentee monarch who preferred to reign as Emperor of Brazil rather than return to Portugal, and his brother Miguel. The power struggle, with strong overtones of absolutism versus liberalism, excited the interest and intervention of other powers. With British help, Pedro defeated Miguel off Cape St. Vincent in 1833, and his expeditionary force marched to Lisbon. Pedro took the throne, though armed struggle continued for months and the lingering bitterness long after that. By 1892 Portugal, racked by wars and the continuing expense of maintaining its African colonies (including those of Mozambique and Angola), declared itself bankrupt. The seeds of discontent with absolutist rule were sown. Kingdom's End Bloodshed would haunt the remaining years of the Portuguese monarchy. On 1 February 1908, the royal family was riding in an open carriage along the Lisbon river front plaza, Terreiro do Paco, when an assassin opened fire and killed King Carlos and the heir to the throne, Prince Luis Filipe. The prince's younger brother, Prince Manuel, was also hit, but he survived and was thus propelled to the throne at the tender age of 19. Amid republican agitation, a surprise uprising led by elements within the armed forces deposed Manuel in 1910. Having ruled for less than three years, Manuel died in exile in 1932 in England. The sudden end of more than seven centuries of monarchy brought confusion and crisis to the country. Presidents and prime ministers were ushered into and out of office an unbelievable 45 times between 1910 and 1926, until a military revolution suspended Portugal's problematic democracy.

Question: "Why was King Carlos assassinated?"

Answer: "His brother wanted the throne"
Answer: no

Problem: Hamilton argued that the natural faculties of blacks were as good as those of free whites, and he warned that the British would arm the slaves if the patriots did not. In his 21st-century biography, Chernow cites this incident as evidence that Hamilton and Laurens saw the Revolution and the struggle against slavery as inseparable. Hamilton attacked his political opponents as demanding freedom for themselves and refusing to allow it to blacks. In January 1785, Hamilton attended the second meeting of the New York Manumission Society (NYMS). John Jay was president and Hamilton was the first secretary and later became president. Chernow notes how the membership soon included many of Hamilton's friends and associates. Hamilton was a member of the committee of the society that petitioned the legislature to end the slave trade, and that succeeded in passing legislation banning the export of slaves from New York. In the same period, Hamilton felt bound by the rule of law of the time and his law practice facilitated the return of a fugitive slave to Henry Laurens of South Carolina. He opposed the compromise at the 1787 Constitutional Convention by which the federal government could not abolish the slave trade for 20 years, and was disappointed when he lost that argument. Hamilton never supported forced emigration for freed slaves. Horton has argued from this that he would be comfortable with a multiracial society, and that this distinguished him from his contemporaries. In international affairs, he supported Toussaint L'Ouverture's black government in Haiti after the revolt that overthrew French control, as he had supported aid to the slaveowners in 1791--both measures hurt France. Scant evidence has been interpreted by a few to indicate Hamilton may have owned household slaves, as did many wealthy New Yorkers (the evidence for this is indirect; McDonald interprets it as referring to paid employees).

Question: "When did Hamilton attend the second meeting of the NYMS where he later became president of?"

Answer: "Before"
Answer:
no
