Step-by-step explanation:
The Acadians were able to use Louisiana's geography to meet their needs in several ways. The hot and humid climate of Louisiana influenced their architectural adaptations, as they built houses with features that helped them cope with the heat. For example, they raised their houses on stilts to protect against flooding and increase air circulation. They also utilized the fertile riverfront land for farming, taking advantage of the Mississippi River for transportation and access to resources. Additionally, the swamps and marshes provided them with a diverse range of food sources, including fish and shellfish.
