The United States is one of the largest countries in the world, so it is no wonder that it has many different physical features and multiple climate types on its territory.
If the major physical features are taken, than the United States can be roughly divided into several physical regions. The eastern coast is dominated by fertile lowlands. Then, there is the Appalachian Mountain Range which is a natural barrier between the east coast and the interior. The central part of the country is dominated by vast lowland grasslands. West of the grasslands are located the Rocky Mountains and the Cascade Mountains, and along the western cost there are lowlands.
The climate is directly dependent on the physical features and location of the continent. The eastern coastline is dominated by maritime climates, having more moderate and wet climates. The Appalachians have montane climate, being colder and wet on one side, while drier on the other side. The central part of the country is dominated by continental climate, having temperatyures extremes in both summer and winter, and being semi-arid. The Rockies and Cascades have montane climate, being colder and wetter than the surrounding area, but also arid areas between them because of the rain shadow effect, domianted by deserts. The western coastline is dominated by maritime climates, making it very wet and moderate in one part, and very hot and dry in the other part.
