step 1 Eugene is between 0 and negative 10 degrees. It's closer to the 0, so let's say about negative 3

Question

Study the large dunes in this image (zoom out to an eye altitude of $\sim 25,000$ feet). These structures can indicate the direction that the wind is blowing. What is the predominant wind direction in this area? (Hint: it is easier to see these features if we exaggerate the vertical scale to do this go to Tools, options, and on the $3 \mathrm{D}$ view tab change the Elevation Exaggeration to $3 .$ To do this on a Mac go to Google Earth then Preferences) a. north to south b. south to north c. east to west d. west to east

Key Concepts

Aeolian Processes

Aeolian processes involve the erosion, transport, and deposition of sediments by wind. These natural actions are key to forming various landforms such as dunes, ripples, and loess, fundamentally shaping desert and coastal environments over time.

Dune Morphology

Dune morphology refers to the structure and shape of sand dunes, which are influenced by wind patterns. As wind blows sand in a particular direction, dunes develop characteristic features such as a gentle slope on the windward side and a steep slip face on the leeward side, reflecting the history of wind movement.

Wind Direction Indicators

Wind direction indicators are geomorphological clues that provide information about the prevailing wind direction. In the context of dunes, the orientation of the slip face, which is the steep side of the dune, typically points in the direction the wind is blowing towards, offering insights into regional wind patterns.
