Some scientists are studying the water quality of a pond near several factories. They find that the pond water is polluted by a chemical common to several factories. The scientists want to identify the source of the chemicals. They decide to compare soil samples taken from around all the factories to identify the source of the leak. If you were one of these scientists, what might be your hypothesis?

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.
