Explain why studying geography helps us to plan for the future.

Studying geography can provide an individual with a holistic understanding of our planet and its systems. Those who study geography are better prepared to understand topics impacting our planet such as climate change, global warming, desertification, El Nino, water resource issues, among others.

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.
