Here's a breakdown:
* Lee: Refers to the side of an object that is sheltered from the wind.
* Slope: Indicates an inclined surface.
How it happens:
1. Wind Erosion: Wind picks up loose sediment, carrying it along.
2. Obstacle Encounter: The wind encounters an obstacle like a rock, hill, or building.
3. Sediment Deposition: The wind slows down behind the obstacle, causing the sediment to settle.
4. Lee Slope Formation: The accumulated sediment forms a slope on the leeward (downwind) side of the obstacle.
Examples:
* Sand Dunes: Sand dunes are classic examples of lee slopes. The wind blows sand up the windward side of the dune, then deposits it on the leeward side.
* Rock Formations: Wind can erode rock formations and deposit sediment on the leeward side, creating unique shapes.
* Artificial Structures: Buildings and fences can also create lee slopes, especially in areas with high wind and loose sediment.
Key Takeaway:
Lee slopes are a common feature in areas with strong winds and loose sediment. They demonstrate the powerful role of wind in shaping landscapes.
