Weathering, Erosion & Deposition of Sediments
Observe how running river water, coastal surf, and desert wind break down and transport earth materials.
Why It Matters:Civil engineers must calculate coastal erosion rates to protect coastal highways, bridges, and housing.

Worked Example
Trace a granite boulder in the mountains through weathering, erosion, and deposition:
1
Weathering Stage
Frost wedging in mountain peaks
Winter ice expands and fractures granite into gravel and sand grains.
2
Erosion Stage
Mountain stream transport
Gravity-driven river currents carry sand downstream, rounding sharp edges.
3
Deposition Stage
River delta sedimentation
As water slows entering the ocean, sand drops to the seabed, forming new delta land.

⚠️ Common Pitfalls & Misconceptions
Thinking mountains never change shape
✗ Believing mountains have always looked identical to how they look today✓ Water, wind, and ice constantly carve and lower mountain peaks over geological time
Even the tallest mountains are gradually reshaped by continuous weathering.
