Let us practise and revise what we learned about exogenetic processes - part ii. Continuing exogenetic processes, deposition and specific la
Core concept
Deposition occurs when erosion agents (water, wind, ice) drop the material they were carrying, forming new landforms like deltas and dunes.
How it works
Rivers create landforms through both erosion (like V-shaped valleys) and deposition (like deltas at river mouths and floodplains).
Why it matters
Wind erosion and deposition are especially significant in deserts, forming landforms like sand dunes and wind-carved rock formations.
Key detail
Glaciers, through erosion and deposition, create distinctive landforms like U-shaped valleys, moraines, and fjords in cold regions.
