<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.

Congress needs to go through a long and careful process to get things done, not to mention them needing to have the majority of congress agree.
The president/executive branch of the government is made up of much less people, as well as the president himself being commander and chief of the military.
Time is very important during a national emergency, and the president can get things done quickly.
Hope this helps.
