Study Notes
Physical Weathering
- Factors affecting physical weathering include temperature changes, freeze-thaw cycles, and moisture, but not vegetation types.
- Rock disintegration occurs without chemical change; relevant processes involve temperature fluctuations or mechanical stress.
Onion Skin Weathering
- The process where surface rock erodes in layers, similar to an onion, due to pressure release is known as exfoliation.
Types of Weathering
- Physical weathering is characterized by the breaking of rocks into smaller pieces without altering their composition.
- The physical breakdown can be caused by various natural elements, including temperature variations and biological activity.
Exogenic Processes
- Exogenic processes are characterized by external forces such as weather, erosion, and other surface-level activities affecting Earth's surface.
- They differ from endogenic processes, which are driven by internal Earth forces, such as volcanic activity.
Root Wedging
- The term for this process is root wedging, where plant roots grow into rock fissures, exerting pressure and causing rocks to break apart.
Distinction in Weathering Types
- Physical weathering results in the fragmentation of rocks, while chemical weathering involves the alteration of minerals within the rocks.
- Understanding the non-exogenic processes helps differentiate between internal Earth dynamics and surface-level interactions.

Description
Test your knowledge on exogenic processes with this quiz! Learn about erosion, mass wasting, and sedimentation, and how these processes shape the Earth's surface. Explore how rocks undergo different exogenic processes and understand how the products of weathering are carried away by erosion and deposited elsewhere. Challenge yourself and expand your understanding of these destructive forces.
