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 picture shows part of the Piney Woods ecoregion in east Texas.
Which of the following best explains the lack of extremely diverse landforms in this ecoregion?

• The high vegetation decreases erosion from water and wind.
• The high amount of vegetation soaks up most of the corrosive water into their leaves.
• The trees broke down all of the previous landforms through weathering.
• The trees in this region hide the diverse landforms underneath them.

The picture shows a map of a part of the Gulf Coast Praries and Marshes ecoregion.  Which of the following best explains how these islands formed?

• They formed as underwater volcanoes erupted and deposited lava.
• They formed as a reef built up deposits so high that it created an abovewater mass.
• They formed as sand from the shore was deposited in a location where water movement slowed down.
