Wind & Beach Erosion

How can you determine wind direction by looking at a sand dune?

• The wind blows up the gentle slope and then down the steeper slope.
• The wind blows up the steeper slope and then down the gentle slope.

This sand dune most likely formed by

• water flowing from the left
• water flowing from the right
• wind blowing from the left
• wind blowing from the right

Sediments deposited by wind are generally

• Sorted
• Unsorted

Sediments deposited by wind are generally... (Choose the answer that is ONLY true for wind)

• Angular
• Rounded
• Pitted
•  Scratched

Identify the sedimentary rock that would eventually form if a sand dune became covered up and turned into rock over millions of years.

• Sandstone
• Conglomerate
• Sand
•  Pebbles
