Because they have different beliefs.
Because some long time ago, Some people wants to have a more new-fashioned synagogues but quite a lot of people disagree. So they spitted into 2 groups. Orthodox and Reform Synagogue. Note: Reform=New-fashioned synagogue Note:Orthodox=Traditional Synagogue
Yes, ALL Orthodox synagogues do, but in the other synagogues, some non-Orthodox Jews will wear their own.
orthodox Jews are traditional and reform Jews have mordenised their traditional ways
Orthodox synagogues tend to adhere more strictly to traditional Jewish practices and teachings, while Reform synagogues are more open to reinterpretation and adaptation of Jewish customs. Orthodox services are typically conducted in Hebrew and are more traditional in structure, while Reform services may incorporate more English and modern music. Both denominations emphasize community, prayer, and study, but Orthodox Jews may have more stringent observance of dietary laws and gender roles.
In my experience (in Orthodox synagogues) it is; but other kinds of synagogues might do things differently. In Ashkenazi Orthodox synagogues, the chazzan stands at the bimah only during the Torah-reading. Otherwise, he has a lectern which is at the front of the synagogue.
It's mostly the Orthodox Jews that do that.
They're only separated in Orthodox synagogues, which make up a minority of synagogues in North America. Orthodox synagogues have separate seating for males and females in order to focus on the prayers instead of on each other.
Orthodox Jewish men go only to Orthodox synagogues. Non-Orthodox Jewish men would be likely to go to non-Orthodox places of worship. In Israel, Canada, the United Kingdom, and the United States, there are prevalent numbers of non-Orthodox or Liberal synagogues. As a result, people in those places who are themselves Liberal can often find a Liberal synagogue in which to worship. Outside of those four countries, it is very rare to find a Liberal synagogue, so Jews of all religiousities (both Liberal and Orthodox) go to Orthodox synagogues for prayer, but will not perform all of the Orthodox Mitzvot when not in synagogue.
