The Arctic Circle.
Urals Mountain runs roughly through Russia and Siberia. Forms a border between Europe and Asia.
If you're referring to latitude and longitude, then one important line of longitude and one of latitude run through Europe: the Prime Meridian and Arctic Circle respectively.
The Arctic Ocean is the only ocean that the equator does not run through. The equator passes through the Atlantic, Pacific, and Indian Oceans but not the Arctic Ocean.
It runs through North Africa (Sudan and Egypt), but it does not run through Southwest Asia at all.
None. The only landmass it passes through is Antarctica, which contains no countries, mainly just science stations run by countries like Britain, Chile, Australia and Argentina. If you are also including the Arctic Circle in this question, the Arctic Circle passes through: Russia, Finland, Sweden, Norway, Iceland (the island of Grimsey), Greenland (which is still sort of technically part of Denmark), Canada, and the United States. So it passes through eight countries.
The Antarctic Circle runs through the Southern Ocean, which surrounds Antarctica.
