Why is there a large desert region in central asia, while the central plains of the interior united states is not a desert? as part of your answer, describe the differences between the geography of central asia, with its relation to the indian ocean, and the central plains of the united states, with its proximity to the gulf of mexico?

The geographical terrain of Central Asia is different from the Atlantic which would be a source of evaporation and precipitation due to the prevailing winds of the monsoons. Although the Indian Ocean does not have a passageway for the monsoons since they are blocked by the Himalayas, it is because of this that warm and moist air drift over the central plains of North America. The temperatures are slightly more extreme in the east which diminishes rain-bearing winds. 

This act gave the federal government the power to relocate any native in the east to territory west of the mississippi river.
