Landforms
A Natural Feature on the earth’s surface.
Landforms are different kinds of formations a place has.
The types of landforms a place has are influenced by its climate
Physical regions are often defined by the landforms found there.

1. Mountain Region
Mountain- a landform that rises at least 2,000 feet above surrounding land; usually wide at the bottom and narrow at the top.
Mountains form a Mountain Range- several mountains in a row.
Example: Rocky Mountains
![Page 11: Physical Regions and Landforms](https://reader033.vdocuments.us/reader033/viewer/2022052523/5561a2b4d8b42ae1538b4b2d/html5/thumbnails/11.jpg)
Plateau
Plateaus- are landforms that are found in mountain regions.
They often come off of mountains.
The Great Plains are located on a plateau that comes off the Rocky Mountains.

2. Valley Region
Valleys are low lands that often lie between mountain ranges.
Good for communities because of the water that runs down from the mountains and they have rich soil to grow crops.

Types of Valleys
Mountain Valley- A valley between two mountain ranges.
Glacial Valley- A valley in a polar region,
formed by glaciers (moving sheets of ice).
AKA: Fjords.
Canyon- A deep valley in an arid region.
Carved into a mountain by water.
Rift- A valley formed along a fault line.

3. River Basin Region
River Basin- a low lying area of land, shaped kind of like a bowl. • Basins are areas that are drained by rivers and
their tributaries. Water from the basins eventually reaches the river mouth and runs into a sea or ocean.
• Tributary- A smaller river or stream that flows into a bigger river.

4. Desert Region
Desert- dry land that receives less than 10 inches of rain a year and has little to no vegetation.
They can be hot or cold.
Examples: Sahara in Africa (Hot) or Antarctica (Cold)

Common Landforms in Deserts
Mesas- a hill that has a flat top and steep sides.
Butte- a steep sided hill with a flat top that usually stands alone around a flat area. A butte is smaller than a mesa.

5. Plains Region
Plains- a large area of flat or gently rolling land. (like Kansas).
This region is often used by ranchers to graze cattle.
Prairie- United states (The Great Plains).
Pampas- South America
Savanna- Africa
Steppe- Russia

6.Coastal Plain Region
Coastal Plain- The area of flat land along a sea or ocean
Example: Beach but not all coastal plains are sandy like a beach.

Peninsula
Is part of a coastal plain that has water on three sides and is attached to another piece of land.
Example: Florida
Cape- like a
Peninsula but is pointy.

Gulfs and Bays
Gulf/Bay- are bodies of water almost surrounded by land.
A gulf is usually bigger than a bay.
They are located next to coastal plains.
Examples: Gulf of Mexico and Bay of Bengal.

Sea
Sea- A large body of water that may be partially enclosed by land.
It is larger than a gulf and smaller than an ocean.
Example: MediterraneanSea.

7. Island Region
Island- a body of land totally surrounded by water.
Archipelago- a series of islands.
Example: Hawaii

Example: strait of Gibraltar
(between Spain & Morocco)
