<span>Sand dunes can encroach on human habitats. Sand dunes move through a few different means, all of them assisted by wind. One way that dunes can move is through saltation, where sand particles skip along the ground like a rock thrown across a pond might skip across the water's surface. When these skipping particles land, they may knock into other particles and cause them to skip as well. With slightly stronger winds, particles collide in mid-air, causing sheet flows. In a major dust storm, dunes may move tens of meters through such sheet flows. And like snow, sand avalanches, falling down the steep slopes of the dunes that face away from the winds, also moving the dunes forward.

The Madisonian model is a structure of government in which the powers of the government are separated into three branches: executive, legislative, and judicial.
It was during the Cold War era that two economic philosophies were predominant: Capitalism and communism--with the United States advocating for the former and the USSR advocating for the latter.
Mid 1990 the economy entered a period of recession. By definition, a recession is " a period of temporary economic decline during which trade and industrial activity are reduced" (online dictionary). During this time jobs became scarce, taxes were increased for corporations and those with high incomes. Additionally, certain programs were cut in order to save money, NAFTA was put into effect between the United States, Mexico, and Canada. Programs like welfare were reformed. The federal minimum wage was increased which ended up affected about 10 million Americans. The average income per household increased to about 37,000.
