What is the difference between weathering and erosion?

Here's a breakdown of the differences between weathering and erosion:

Weathering

• Definition: Weathering is the in-situ breakdown of rocks, soils, and minerals through direct contact with the Earth's atmosphere. It essentially weakens or disintegrates materials.
• Process: Weathering involves physical and chemical processes.
  • Physical%20Weathering: Also known as mechanical weathering, it involves the disintegration of rocks without any change in their chemical composition. Examples include freeze-thaw, abrasion, and exfoliation.
  • Chemical%20Weathering: Involves the decomposition of rocks through chemical reactions. Examples include oxidation, hydrolysis, and carbonation.
• Result: Weathering creates smaller particles and alters the composition of the original material in place. It prepares the material for erosion.

Erosion

• Definition: Erosion is the process by which weathered material is transported and moved away from its original location.
• Process: Erosion is driven by agents like:
  • Water%20Erosion: Rivers, streams, and rainfall carry away weathered material.
  • Wind%20Erosion: Wind transports small particles, especially in arid environments.
  • Glacial%20Erosion: Glaciers are powerful agents of erosion, carving out valleys and carrying massive amounts of debris.
  • Gravity: Mass wasting events like landslides are a form of erosion.
• Result: Erosion moves the products of weathering to new locations, often reshaping landscapes.

Feature	Weathering	Erosion
Definition	Breakdown of rocks and minerals in situ	Movement of weathered material
Action	Disintegrates and decomposes	Transports
Location	Occurs at the site of the original material	Moves material away from its original site
Agents	Atmosphere, water, ice, biological activity	Water, wind, ice, gravity
Relationship	Prepares material for erosion; weakens rocks	Carries away the products of weathering
