This picture shows sand dunes on Padre Island, Texas, in the Gulf Coast Prairies and Marshes ecoregion.
The sand dunes most likely formed by --

• The deposition of sand carried by swift wind blowing along the coast.
• strong waves dumping chunks of the ocean floor onto the beach.
• a primitive river that flowed toward the ocean and carved out the sand dunes.
• Land that slightly uplifted when tectonic plates moved under the beach sand.

The Brazos River is the longest river inTexas, emptying into the Gulf of Mexico.  What type of land formation would you expect to find where the river deposits sediments as it reaches the Gulf?

• A mountain
• A cave
• A valley
• A delta

This landform was created by-

• glacier
• wind
• landslide
• water
