These states are located within North America and are bordered by Canada to the north and Mexico to the south. They offer diverse landscapes, ranging from the stunning Rocky Mountains in Colorado to the vibrant beaches of Florida.

Land Area vs Water Area

When it comes to land area, the continental United States covers approximately 2,963,143 square miles. This includes vast plains, mountain ranges, deserts, and forests.

When talking about the area of the United States including Alaska and Hawaii, it is impossible to ignore the unique and beautiful state of Hawaii.

Island Geography

The Hawaiian Islands are not only known for their beauty but also for their fascinating geography. These islands were formed through volcanic activity millions of years ago, and their diverse landscapes bear witness to this fiery past. From the active Kilauea volcano on the Big Island to the towering sea cliffs of Molokai’s Kalaupapa Peninsula, Hawaii’s geography is a testament to the powerful forces that shaped the islands over time.

Volcanic Origins

Hawaii’s volcanic origins are a significant part of its identity. The islands were formed by a series of volcanic eruptions, with the oldest islands being towards the northwest and the youngest towards the southeast. The Big Island is home to some of the most active volcanoes in the world, including Kilauea and Mauna Loa. These volcanoes continue to shape the landscape with ongoing eruptions and lava flows, creating new land and adding to the island’s area.

Tropical Climate

One of the things that make Hawaii a popular tourist destination is its tropical climate. The islands enjoy warm temperatures year-round, with average highs ranging from the mid-70s to the mid-80s Fahrenheit. The trade winds that blow across the islands provide a pleasant breeze, making the weather even more enjoyable. Hawaii’s climate, combined with its stunning beaches and lush vegetation, creates the perfect environment for outdoor activities such as surfing, hiking, and snorkeling.
