Answer: The release of methane from thawed permafrost
Explanation:
With increasing global warming, permafrost in the arctic is melting. The carbon and methyl clathrates present in permafrost escape into the atmosphere to form carbon dioxide and methane, both greenhouse gases.
In the Arctic, molecules of methane are trapped in ice crystals as methyl clathrates. When the temperature increases, these crystals release methyl clathrates which become methane when in contact with the atmosphere.
The cause of the increasing atmospheric 
is due to the the thawing of dead organisms present in the permafrost. As the permafrost melts, these organisms decay and release into the atmosphere.

All the phase changes involve transfer of energy
gravity affects the water cycle because it pulls denser water down and less dense air up. it also causes precipitation to fall from clouds. sunlight provides energy for the water cycle
Answer:
Apartheid was an official policy of racial segregation in South Africa from 1948 to 1994. Although racial segregation and discrimination arose earlier, after the 1948 general election, people were divided into classes by law: black, white, colored, and Asian. People of different skin colors who had lived together so far were separated, and two infrastructures were set up in the country, one for whites and the other for blacks.
This situation was clearly similar to that of the racial segregation that took place in the southern United States from the end of the Civil War until the 1960s, through which the Democratic governments of the southern states segregated African-American populations from their territories, relegating them to a citizenship of inferior conditions, with worse public services and a general lack of rights compared to those of whites.
