What was the difference in the purpose of Christian and Muslim temples?

Christianity and Islam are different world religions based on belief in a supreme being. Let’s write the differences between these religions:
1) in Christianity they pray in the church, and in Islam – in the mosque.
2) the main distinguishing sign of religions is domes: in Christian churches they are crowned with a cross, and in Muslim ones – with a crescent.
4) the mosque is decorated with various geometric and floral ornaments. There are more images of living beings in the church.
5) the two religions have a different approach to prayer. Muslims call for the service by singing from the top of the minaret, and for Christians – the sound of bells.
