This might not help but: South America can be divided into three physical regions: mountains and highlands, river basins, and coastal plains. Mountains and coastal plains generally run in a north-south direction, while highlands and river basins generally run in an east-west direction. South America’s extreme geographic variation contributes to the continent’s large number of biomes. A biome is a community of animals and plants that spreads over an area with a relatively uniform climate.
Mountains -South America’s primary mountain system, the Andes, is also the world’s longest. The range covers about 8,850 kilometers (5,500 miles). Situated on the far western edge of the continent, the Andes stretch from the southern tip to the northernmost coast of South America. There are hundreds of peaks more than 4,500 meters (15,000 feet) tall, many of which are volcanic. Rivers- South America has three important river basins: the Amazon, Orinoco, and Paraguay/Paraná.
The Amazon River basin has an area of almost 7 million square kilometers (2.7 million square miles), making it the largest watershed in the world. The basin, which covers most of northern South America, is fed by tributaries from the glaciers of the Andes. Every second, the Amazon River empties 209,000 cubic meters (7,381,000 cubic feet) of freshwater into the Atlantic Ocean. Plains-A coastal plain is an area of low, flat land next to a seacoast. South American coastal plains are found on the northeastern coast of Brazil, on the Atlantic Ocean, and the western, Pacific coast of Peru and Chile. The coastal plains of northeastern Brazil are extremely dry. The Brazilian Highlands act as a wedge that pushes moist sea winds away from the coastal plains.
There were more towns to trade with, more goods, and the slave market increased GREATLY and more spread of influence, Islam influence grew TREMENDOUSLY.
I believe you could be referring to the spouse of the President, also called the First Lady of the United States. The spouse of the President is non-elected and not confirmed by the Senate. Although she does not have real power, she can be very influential and has a prominent presence in the live of the nation.
