Final answer:
A minaret is the tall, slender tower of a mosque from which the call to prayer is announced, marking the mosque's location and facilitating the faithful's adherence to prayer times.
Step-by-step explanation:
To mark a mosque's location and allow the faithful to be called to prayer?, the distinguishing feature used is a minaret. A minaret is a tall, slender tower attached to a mosque from which the call to prayer is made. While a mihrab is an important element, indicating the direction of Mecca within a mosque, the minaret serves as the physical landmark for the mosque's location and for the call to prayer. The minaret's function is vital for Muslims as it symbolically connects the sky and earth, facilitating the notion of being called to prayer, something that resonates with the community of believers locally and within earshot.
