Question

Where are jet streams found?

close to the poles
in the middle latitude
toward the equator
in the upper atmosphere

Answer 1

Jet streams are primarily found in the upper atmosphere, specifically in the tropopause region, which is the boundary between the troposphere and the stratosphere. They are high-altitude, fast-flowing air currents that typically occur near the boundaries between different air masses and are most prominent in the middle latitudes. Therefore, the best answer from your options would be **in the upper atmosphere**. However, it's also worth noting that they can be influenced by conditions close to the poles and in the middle latitudes, but their main location is in the upper atmosphere.
