Question

describing wind erosion and deposition
match each term about wind erosion and deposition with its description.
terms: deflation, abrasion, erosion, sand dune
descriptions (partially visible):

• soil deposited by wind as sediment
• the process by which wind picks up loose sediment
• the process by which wind carries and deposits sediment
• a deposit of wind - blown sand that forms over time

(note: the image contains a matching - style question layout with terms and description boxes, and some arrows for matching.)

Explanation:

To solve this matching problem about wind erosion and deposition, we analyze each term and its description:

1. Defining Terms:

• Deflation: The process where wind removes (erodes) fine sediment (like sand, silt) from a surface. So it matches "the process by which wind removes surface materials".
• Abrasion: Wind - carried sediment (like sand) scrapes against surfaces, wearing them down. This matches "the grinding away of rock or other surfaces as particles carried by wind, water, or ice scrape against them".
• Loess: A deposit of wind - blown fine, yellowish - brown silt. It matches "wind - deposited sediment that consists of fine particles of clay and silt".
• Sand Dune: A mound of wind - deposited sand, often found in deserts or near beaches. It matches "a deposit of wind - blown sand that forms in a place where the wind slows down".

Matching:

• Loess → wind - deposited sediment (fine clay/silt)
• Abrasion → grinding by wind - carried particles
• Deflation → wind removes surface materials
• Sand Dune → wind - blown sand deposit (where wind slows)

If we assume the top descriptions (from the blurry image) are:

1. wind - deposited sediment (fine clay/silt)
2. grinding by wind - carried particles
3. wind removes surface materials
4. wind - blown sand deposit (where wind slows)

Then the matches are:

• Loess → First description (wind - deposited fine sediment)
• Abrasion → Second description (grinding)
• Deflation → Third description (wind removes materials)
• Sand Dune → Fourth description (sand deposit from slow wind)

(Note: The exact matching depends on the precise wording of the descriptions, but this is the logical pairing based on geological definitions of wind erosion/deposition processes.)
