Answer:
The geography of the Puget Sound lowlands has played a significant role in shaping its physical development. The region is located in a coastal area with low-lying terrain, which has made it vulnerable to flooding and erosion. The region's proximity to the Pacific Ocean has also resulted in a temperate climate with abundant rainfall, which has influenced the growth of vegetation and wildlife in the area. Additionally, the presence of the Olympic and Cascade mountain ranges has impacted the topography of the region and influenced the distribution of resources and settlements.
