PLEEEAAASSSEE Answer ASAP. 20 points! which of the following was a major change that resulted from the completion of the Transcontinental Railroad.

The answer is that goods could be shipped east to west much faster.

Explanation:

The Transcontinental Railroad allowed goods to be shipped east to west much faster because the railroad had almost a "straight" path to its destination. Unlike the normal mode of transportation at the time, which was usually by wagons or by switching to multiple different trains, the Transcontinental Railroad allowed products to reach its destination at a much faster rate. By reaching its destination faster, the products could be sold on the market faster and with a lower chance of spoilage for certain products.

Explanation:

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.
