Shaping of the Earth’s Surface
Discover the forces and processes that shape the atmosphere and climate. Explore how atmosphere and climate 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 atmosphere and climate 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 atmosphere and climate.
While studying: connect each process with the changes it produces, observe examples of atmosphere and climate, and think about how the atmosphere and climate 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 atmosphere and climate.
🌦️ Weathering
Understand how rocks break down at or near the atmosphere and climate 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 atmosphere and climate is varied and continually changing.
