Shaping of the Earth’s Surface
Discover the forces and processes that shape the Earth’s surface. Explore how landforms develop and change over time, and use the chapter resources to strengthen your understanding through visual learning, notes and practice.
Chapter at a Glance
The Earth’s surface is continually shaped by natural processes. Some forces originate within the Earth, while others act on the surface through water, wind, ice and changes in temperature. Over time, these processes create and modify a wide variety of landforms.
While studying: connect each process with the changes it produces, observe examples of landforms, and think about how the Earth’s surface changes over short and long periods of time.

🌋 Forces Within the Earth
Study how internal forces can raise, lower, fold or fracture parts of the Earth’s crust and contribute to the formation of landforms.
🌦️ Weathering
Understand how rocks break down at or near the Earth’s surface through physical, chemical and biological processes.
🌊 Erosion and Transport
Explore how moving water, wind, ice and other agents wear away and carry material from one place to another.
🏞️ Deposition
Learn how transported sediments settle and accumulate, helping create or reshape features of the landscape.
⛰️ Changing Landforms
Compare how different natural processes shape mountains, valleys, plains and other features over time.
🔎 Observe and Explain
Use examples and evidence to connect a landform with the process or processes that may have shaped it.

Landscapes develop through the interaction of different processes. Understanding how material is broken down, moved and deposited helps explain why the Earth’s surface is varied and continually changing.
