What defines a gulf in geographical terms?

A gulf is defined as a large bay that is an arm of an ocean or sea. This means it is a significant indentation into the coastline, often characterized by its size and depth compared to smaller bodies of water like bays or coves. Gulfs are typically larger than bays and can provide shelter for ships, making them valuable for trade and maritime activities. The geographical significance of a gulf stems from its connection to larger bodies of water and its potential impacts on climate, marine ecosystems, and human activities. Understanding this definition allows one to differentiate gulfs from other geographical features, such as straits or lakes, which have distinct characteristics and implications.
