Why did many Greek settlements develop around the coastline?

Many Greek settlements developed around the coastline because the sea provided easy access to transportation, trade, and communication with other communities. The coastline also offered rich fishing resources and fertile land for agriculture. Additionally, the Greek city-states were vulnerable to attacks from enemies, and the natural barriers of the sea helped to protect these settlements from invasion. The coastal location also allowed for the establishment of ports, which were essential for conducting maritime trade and maintaining economic prosperity. Overall, the coastline provided numerous advantages for Greek settlements, leading to their development and growth in these areas.
