GSCI 100 - Intro Geology

The Challenge: Identify seven (7) desert landforms in Google Earth from the following list:

• a star dune
• a transverse dune
• a parabolic (blowout) dune
• a barchan dune
• a longitudinal (linear) dune
• an alluvial fan
• a playa
• a mesa
• a yardang
• an arroyo

For each of the landforms that you identify, create a placemark (make sure the thumbtack points directly to the feature in question) and include a brief description (in the Description box) of how the feature is formed, including whether it is a result of erosion or deposition. If the feature is formed by blowing winds, indicate the direction that the prevailing winds are blowing. To receive credit you must e-mail me these seven placemarks in a single folder entitled “[insert Your Name]’s GeoChallenge #21 Placemarks”. Try to include features from no less than 5 different continents.
