Answer 1They are two 'mounts' next to each other.Mt Zion was a Jebusite stronghold captured by David (1Kings 8:1; 1Chronicles 11:5) (2Samuel 5:6, 7, 9) which became his royal residence (Psalm 2:6). When the Ark of the Covenant was transferred there it became especially holy to God. (2Samuel 6:17).Mt Moriah was north of Zion, where the Temple was built during Solomon's reign. Eventually the term "Holy Mountain" and "ZION" came to refer to the combined area of Zion and Moriah, Jerusalem itself.(Isaiah 66:20).[Comment moved to Discussion Section.]Answer 2Yes and No.Historically, Mount Zion was used interchangeably with Mount Moriah. Both referred to the Temple Mount/Foundation Stone where the Dome of the Rock Shrine currently sits. It is in this location that the Jebusites had their fortress, David had his palace in close proximity, and Solomon built the Temple.About 2000 years ago, Judeans started referring to a second mountain, to the southwest of the Temple Mount as Mount Zion. This mountain is currently located to the south of the Armenian Quarter and is still called Mount Zion. They stopped using the term "Mount Zion" to refer to the Temple Mount and instead used Mount Moriah to exclusively refer to that.
The "western wall" of the Temple Mount, also known as the "wailing wall", in Jerusalem, is probably the most holy site for the Jewish people. It is the exposed surviving wall of the Temple that stood most recently until +/- 70 C.E. (A.D.) when it was destroyed by the Romans. Jews from around the world come to this location to pray, and to leave written prayers stuck in between the stones. It is called the "wailing wall" because it is a place of lamentation and anguish over that destruction. The Temple Mount itself is important, perhaps equally so, because it sits on top of Mount Moriah, the historical site where Abraham was said to have sacrificed a ram instead of his son Issac, thus departing from prior cults of human/child sacrifices to animal sacrifices. Because of its relationship to Abraham, it is thus also a holy site for Christians and Muslims alike. The only house of worship on the Temple Mount today is the Al-Aqsa Mosque, which houses the Dome of the Rock, which is that rocky outcropping of Mount Moriah that lays intentionally exposed to view.
