Topography and Landforms
• In 1804 Meriwether Lewis and William
Clark set out on an expedition to explore
the land between the Mississippi River and
the Pacific Ocean just purchased from
France.
• This purchase was called the Louisiana
Purchase.
Section 1
Topography - the shape of the land, including
elevation, relief, and landforms.
Elevation – height above sea level
Relief – difference in elevation between
highest and lowest point
Landforms – feature of topography formed
by the processes that shape Earth’s surface
• The highest elevation that Lewis and
Clark’s expedition took them on was 2,200
meters.
• This location was the Lemhi Pass in the
Rocky Mountains.
Landforms- a feature of topography such as a hill or
valley formed by the processes that shape the earth’s
surface.
There are three main types of landforms.
1. Plains- a landform made up of nearly flat or gently
rolling land with low relief. A plain that lies along a
seacoast is called a coastal plain.
2. Mountains- A landform with high elevation and high
relief.
3. Plateaus- a landform that has high elevation and a
more or less level surface
The two plateau regions Lewis and Clark traveled through
Was the Columbia Plateau and Ozark Plateau
A landform region is a large area where the topography is
made up of one type of landform.
Two landform regions in the book are the Great Plains and
the Rocky Mountains.
Mountain range- a group of mountains that are
closely related in shape, structure, and age.
Mountain system- the different mountain ranges
in a region
Mountain belt- the largest unit of ranges and
systems.
Interior Plains: plain that lies away from the coast
