US Biomes Quiz: Quick Study Notes

The United States features a diverse array of biomes due to its vast size and varied climate. From the frozen tundra of Alaska to the arid deserts of the Southwest, understanding these ecosystems is key to mastering US geography.

Deserts Found in the Southwest (e.g., Mojave, Sonoran). Characterized by low precipitation (< 10 inches/year) and specialized plants like cacti.
Grasslands Dominating the Great Plains (the “Breadbasket”). Known for fertile soil, few trees, and historical herds of bison.
Temperate Forests Cover much of the Eastern US. Defined by deciduous trees (oaks, maples) that shed leaves in winter and distinct seasonal changes.
Tundra Located primarily in Alaska. Features permafrost (frozen soil), extremely cold temperatures, short growing seasons, and no trees.

Key Takeaways

  • Precipitation is the primary factor determining whether a region becomes a forest, grassland, or desert.
  • The Great Plains act as a transition zone between the wetter forests of the East and the drier landscapes of the West.
  • Deciduous trees in temperate forests adapt to cold winters by dropping leaves to conserve water.
  • Permafrost prevents deep root systems, making tree growth impossible in the Tundra.
  • US Deserts are often located in the rain shadow of major mountain ranges like the Sierra Nevada.
Where is the Tundra biome located in the US?

In the United States, the Arctic tundra is primarily located in Alaska, specifically along the northern and western coasts where the climate is too cold for trees.

What defines the US Grasslands?

The Grasslands, primarily the Great Plains, are defined by flat terrain, fertile soil ideal for agriculture, moderate rainfall, and a dominance of grasses rather than trees.

Which trees are common in Temperate Forests?

Temperate forests in the Eastern US are dominated by deciduous trees such as oak, maple, hickory, and beech, which lose their leaves annually.

What are the major US Deserts?

The four major deserts in the United States are the Great Basin, Mojave, Sonoran, and Chihuahuan deserts, all located in the western and southwestern regions.

What is Permafrost?

Permafrost is soil that remains completely frozen for two or more years consecutively. It is a defining characteristic of the Tundra biome and restricts vegetation growth.
