Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the eolian erosion types?Deflation (removal of fine particles) and abrasion (grinding by wind-borne particles)
2. What is the primary dune morphologies?Barchan, transverse, longitudinal, and star dunes, determined by wind and sand supply
3. How does wind move sand and dust?Wind moves tiny dust in suspension, makes sand bounce in saltation, and rolls larger grains in surface creep. These actions carry particles over long distances.
4. Why do deserts have sand dunes?Deserts have dunes because wind drops sand in piles. The shape of each dune depends on how much sand there is and which way the wind blows.

Eolian Geomorphology: The study of landforms created by wind erosion, transportation, and deposition.
Saltation: The process where sand grains bounce and hop along the ground, driven by wind.
Ventifacts: Rocks that have been shaped, polished, and abraded by wind-blown sand.
Yardangs: Elongated, wind-sculpted ridges found in desert environments, often parallel to the prevailing wind.
