Explanation:
The United States is located in North America in the Western Hemisphere. It spans a large amount of the continent, so it covers many areas with unique climates.
The Northeast has a lot of forest cover, and encounters very diverse climates throughout the year, from bitter winters to blistering summers, and have even experienced hurricanes.
The Southeast is generally mild, and experiences warm weather year round. The further south you go, the warmer it gets. You also see more bayous and swamps in the south. The northern ends of the Southeast such as North & South Carolina can experience some snow and colder weather in the winter.
The Midwest is also mild, and generally flat, which makes it ideal for agriculture.
As you go west, you will find more mountainous regions, as well as arid desert landscapes. The Southwest is the pinnacle of these desert landscapes, seeing hot weather in the day, and cold weather in the night, with high temperatures year round.
And finally, the Northwest is a mild climate, with high mountains and abundant rain.
The American Southwest was settled by European colonists from spain . (:
