Answer:
Houses covered with grass or animal hides
Step-by-step explanation:
Areas on the Gulf Coast most likely did not have adobe because it was not available to obtain. Pueblos are dwellings found more in the Southwest and not the Gulf Coast. Tipis are found in more forested and mountainous areas. Since the gulf coast is flatter, it would make sense that the houses would be covered with grass or animal hides because there is lots of grass and it is easy to obtain animal hides because it is so flat.
Have a wonderful day! :D
