What type of land features are formed by wind
erosion?

• Ventifacts, the most common products of wind
  erosion, are rock fragments
• found wherever wind blows sand grains
  against rock surfaces. Fragment
• surfaces are characterized by a relatively high
  gloss or sheen, and by
• facets, pits, gouges and ridges. Fragment faces
  may display a variable
• number of facets that meet with sharp ridges
• frosted sand grains appear just like frosted
  glass, due to impact, with resulting pitted
• surface.
• Deflation - this process involves the
  picking up and removal of loose rock
• material by the wind, and creates several
  recognizable landscape features.
• These include
• blowouts are small basins scooped out in soft
  unconsolidated deposits. These
• basins range from a few meters to several
  kilometers in diameter. They are
• common in the high plains of eastern New Mexico
  and western Texas, where
• bedrock is loosely cemented by calcium
  carbonate.
• desert pavement represents surfaces where
  deflation removes all sand and finer grains,
  leaving behind larger particles of pebble- or
  cobble-size.
