Explain why the jet stream looks so different in picture one and picture two. refer to the tutorial to answer this question. answer using complete sentences.

The picture on the left is an illustration of the jet stream on the northern hemisphere during summer. In the tutorial it states, the temperature contrast between cold and warm air masses are smaller, so the jet stream is not that strong only travelling at 50-70 mph. The picture to the right is an illustration of the jet stream on the northern hemisphere during winter. In the tutorial it states the temperature contrast between cold and warm air masses are greater, so the jet stream is very strong travelling at 90-160 mph.

Explanation:

Trust me this the correct answer.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
