Physical Features of the United States

Get ready to explore America's amazing landscape! From towering mountains to mighty rivers, our country has incredible physical features that make it unique and beautiful.

What Are Physical Features?

Physical Features Are Natural Landforms!

Physical features are parts of the Earth's surface that were formed by nature, not built by people. Mountains, rivers, lakes, oceans, plains, and deserts are all physical features!

Remember: Physical features are different from human features (like cities, roads, and buildings). Physical features were created by nature over millions of years!

Types of Physical Features

Let's learn about the different types of physical features you can find across the United States!

mountain symbol

Mountains

Very tall landforms that rise high above the surrounding land. They often have rocky peaks and steep sides.

US Examples: Rocky Mountains, Appalachian Mountains, Sierra Nevada
river symbol

Rivers

Large streams of fresh water that flow across the land toward oceans, lakes, or other rivers.

US Examples: Mississippi River, Colorado River, Missouri River
lake symbol

Lakes

Large bodies of water surrounded by land. Lakes contain fresh water and can be very large or small.

US Examples: Great Lakes, Lake Tahoe, Great Salt Lake
plains symbol

Plains

Large areas of flat or gently rolling land. Plains are often covered with grass and are good for farming.

US Examples: Great Plains, Atlantic Coastal Plain
desert symbol

Deserts

Very dry areas that get little rainfall. Deserts can be hot or cold, but they all have little water.

US Examples: Mojave Desert, Sonoran Desert, Great Basin Desert
coast symbol

Coastlines

Where the land meets the ocean. Coastlines can have beaches, cliffs, bays, and harbors.

US Examples: Atlantic Coast, Pacific Coast, Gulf Coast

Famous US Physical Features

The United States has many amazing physical features. Let's learn about some of the most famous ones!

mountain symbol Major Mountain Ranges

Mountains cover about one-fifth of the United States. Here are the major ranges:

Rocky Mountains Stretch over 3,000 miles from Canada to New Mexico. They include some of the highest peaks in North America!
Appalachian Mountains Run along the eastern United States. They are some of the oldest mountains in the world!
Sierra Nevada Located in California. Home to Mount Whitney, the highest peak in the lower 48 states!
Cascade Range Found in the Pacific Northwest. Includes famous volcanoes like Mount Rainier!

Fun Fact: The Rocky Mountains are so long that they pass through six US states: Montana, Idaho, Wyoming, Colorado, Utah, and New Mexico!

river symbol Major Rivers

Rivers are like highways of water that flow across our country. Here are some important ones:

Mississippi River The second-longest river in North America! It flows from Minnesota to the Gulf of Mexico.
Missouri River The longest river in the United States! It joins the Mississippi River.
Colorado River Carved the Grand Canyon over millions of years. Provides water to the Southwest.
Rio Grande Forms part of the border between the United States and Mexico.

lake symbol The Great Lakes

The five Great Lakes form the largest group of freshwater lakes in the world! Remember them with: HOMES

H - Lake Huron Second largest of the Great Lakes
O - Lake Ontario Smallest and easternmost Great Lake
M - Lake Michigan Only Great Lake entirely within the US
E - Lake Erie Shallowest and warmest Great Lake
S - Lake Superior Largest freshwater lake in the world by surface area!

Fun Fact: The Great Lakes contain about 21% of the world's fresh surface water! That's a lot of water!
