Explanation:

Question 6

Jet streams are fast - flowing air currents in the atmosphere. The troposphere is the lowest layer of the atmosphere, and jet streams are located near the top of the troposphere. The stratosphere is above the troposphere and has different characteristics (e.g., ozone layer), the thermosphere is much higher up (where auroras occur), and the mesosphere is between the stratosphere and thermosphere (where meteors burn up). So the jet stream is in the troposphere.

A warm front is associated with a sequence of clouds that starts with high - level clouds like cirrus, then cirrostratus, altostratus, and finally nimbostratus (which brings steady precipitation). A cold front is associated with a more rapid change and often has cumulonimbus clouds and a different cloud sequence. So the front moving past is a warm front.

Cold fronts move quickly and can cause strong uplift of warm, moist air, which leads to the formation of thunderstorms and tornadoes. Warm fronts usually bring more gradual, steady precipitation. So thunderstorms or tornadoes are expected from a cold front.

Answer:

D) troposphere
