Write notes to support your argument about the benefits and drawbacks of early technology on the environment based on what you have learned in this lesson.

The benefits were that the dam could produce electricity, irrigation for farmland, and jobs for workers during the Great Depression. The draw backs were that 81 people lost their falls mainly due to falling but also other deaths.

To construct the dam, they needed to clear thousands of acres of land including forests and people's home's which costed tens of million dollars. This also had a big affect on the Indians because they can't practice their ritual with salmon.

Fish including steel head, salmon, and more couldn't get up the Columbia River like they usually did before the construction of the dam. The workers had long shift hours and a short thirty-minute break lunch. Workers were so fatigued that if you took a rest you would have been replaced. In my opinion the dam was not "America's pride" and shouldn't be because of all the torture.

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.
