USA HISTORY

Detailed explanation-1: -They are flatlands that rise gently as you travel from east to west (toward the Rocky Mountains.) It is a dry area with low rainfall. Because it is so dry and often windy, dust storms are common. Over many years the land has been eroded by wind and water from storms that blow or wash away topsoil.

Detailed explanation-2: -The geographical features of the Great Plains include flat grasslands called prairies, river systems, and a rolling plateau that stretches over a long distance, so the land still appears generally flat.

Detailed explanation-3: -Prairies are enormous stretches of flat grassland with moderate temperatures, moderate rainfall, and few trees. When people talk about the prairie, they are usually referring to the golden, wheat-covered land in the middle of North America.

Detailed explanation-4: -Despite its name, the Great Plains region is not entirely flat, changing in elevation from 1830 meters (6000 feet) on its western edge to 460 meters (1500 feet) on its eastern edge.
