Landforms
14
Concepts
Landforms are features that make up the Earths
surface. Some landforms are created by the action
of wind, water and ice. Mountains, faults, and
volcanoes are created by the movement of the
Earths crust and other tectonic activity.
Topographic maps and models are used to represent
landforms.

Mountains
A high landform with steep sides
higher than a hill. Mountains are found on land
and on the ocean floor.

Mesa
This is a landform that looks like a high, flat
table. Mesas are common in the southwest United S

Plateau
A plateau is a high , nearly flat uplifted area
composed of horizontal layers of rock..
