, why did détente end?

Détente ended after the Soviet intervention in Afghanistan, which led to the United States boycott of the 1980 Olympics, held in Moscow. Ronald Reagan's election as president in 1980, based in large part on an anti-détente campaign, marked the close of détente and a return to Cold War tensions. hope that helps love!

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
