What causes polar jet streams to form?(1 point) Responses warm and cold air masses warm and cold air masses high-pressure systems high-pressure systems air masses moving away from each other air masses moving away from each other rapid changes in wind direction

Answer 1

Polar jet streams are primarily caused by the interaction between warm and cold air masses. The contrast in temperatures between these air masses creates differences in air pressure, which leads to the formation of strong winds at high altitudes. Therefore, the correct response is warm and cold air masses.
