Shaping landscapes 4.6: 
Wind erosion and human effects

Slide 1 - Slide

Slide 2 - Video

Step 1
Step 2
Step 3
Sediments sink downwards
When the river deposits more material than the sea can remove it, sediment plumes are formed
River slows down in lower course and can no longer carry the sediments

Slide 3 - Drag question

Describe in your own words how hurricanes are formed (use full sentences!)

Slide 4 - Open question

Goals
After studying this section, you will be able to:

- Explain how wind forms the landscape
- Explain how human actions contribute to wind erosion

Slide 5 - Slide

Wind erosion
No plant roots that hold the soil together.
Easy for the wind to blow the dry soil away.

Slide 6 - Slide

Why are plants so effective against wind erosion?

1. Plants slow the wind down at ground level, which makes it is more difficult for the wind to “grab” the sediment.

2. The roots of the plants hold soil together, wind cannot move it easily.

Talking point

Many of the countries dealing with desertification are LEDCs (Less deveolped countries). These countries might not have a lot of money to prevent soil erosion. 

What would you advise their governments?
