Step-by-step explanation:
The Appalachian Highlands are a mountain range that run roughly along the northeast of the United States. It includes several subranges, such as the White, Adirondack and Catskill Mountains.
The Piedmont Plateau is an area located in the northeastern United States, between the Appalachian Mountains and the Atlantic and Gulf coastal plain. Several systems of waterfalls mark the western edge of the Piedmont Plateau.
The Ozark Highlands is a small range of low mountains and hills in south central US, with most of them inside the state of Missouri, but also extending to Arkansas, Oklahoma and Kansas.
The Central Lowlands and Great Plains are two contiguous regions that dominate the central United States, extending roughly from the northern border with Canada, continue south across through the Midwest, all the way to the southern border with Mexico through Texas.
The Superior Uplands refers to a heavily wooded lake area roughly south and west of Lake Superior, between the states of Wisconsin, Minnesota and Michigan.
The Rocky Mountain Region is the highest and longest range of mountains in the U.S., stretching for over 3,000 kilometers (roughly 1,900 miles), and it contains most highest mountains in the continental United States, like Mount Elbert (4,400 meters / 14,000 ft high).
The Intermountain Region is a region located in the western United States, sitting between the Rocky Mountains and the Sierra Nevada. It contains the Great Basin and Great Salt Lake.
The Pacific Coast Mountains and Valleys refers to the continous mountain ranges that stretch along the Pacific Coast of North America, all the way from the Pacific coast of Alaska down south to the Pacific coast of California and beyond into Mexico. It includes Denali, formerly Mount McKinley, the tallest mountain in the United States (6,144 meters / 20,156 feet).
The Hawaiian Islands are a series of Volcanic Mountains, that is, the islands were created as a result of volcanic eruptions. Many of the Hawaiian volcanoes are active to this day.
