Question

select the correct answer(s) from the list(s). (1 point)
the polar jet stream forms at degrees latitude where air masses meet cold air from higher latitudes.
60
30
90

Explanation:

The polar jet stream forms at around 60 degrees latitude. At this latitude, warm air masses (from lower latitudes) meet cold air from higher latitudes. The 30 - degree latitude is associated with the subtropical jet stream, and 90 degrees is the pole (not where the polar jet stream forms from the meeting of these air masses). For the air mass, it should be "warm" (though the dropdown isn't fully shown, based on jet stream formation: polar jet stream is at ~60° where warm (tropical) air meets cold polar air). So the first blank (latitude) answer is 60.

Answer:

60
