Alaska Landforms & Physical Regions Quiz: Quick Study Notes
Alaska’s geography is defined by its massive scale and dramatic features. From the temperate rainforests of the Southeast “Panhandle” to the frozen tundra of the North Slope, the state encompasses diverse physical regions shaped by tectonic activity, glaciation, and extreme latitude.
Key Takeaways

- The state is divided into five regions: Southeast, Southcentral, Southwest, Interior, and Far North.
- Glaciers cover approximately 29,000 square miles of the state (about 5% of the total area).
- Permafrost (permanently frozen ground) creates unique engineering challenges in the tundra.
- The Inside Passage is a network of fjords and islands protected from the open ocean.
