Mt. redoubt’s seismic activity is due to the interaction of which two tectonic plates
frosja888 [35]

Answer:

Correct answer is: Due to interaction between Pacific and North American plate.

Explanation:

Mountain Redoubt is located in south Alaska. Mentioned mountain is in the vicinity of convergent plate boundary between North American and Pacific plate.

Convergent boundary means that those plates are <em>colliding</em>. One plate always slides beneath another, and in this case Pacific plate slides beneath North American. Area of collision is known as subduction zone.

Pacific plate is oceanic plate, and North American is continental plate. Oceanic plates <u>always slides</u> beneath continental ones. Reason for that is due to their density. Oceanic plates are denser, so they go under continental ones.

Pacific and North American plate interaction is typicall oceanic-continetal boundary where <em>earthquakes</em> (seismic activity) and <em>active volcanoes</em> are common. Some of the strongest earthquakes happened in this area. That was in 1964 in Prince William Sound in the south coast of Alaska. Magnitude was 9.2M, second strongest quake ever recorded in world's history.

As far back as ancient Greece, farmers utilized it for mechanical activities like grinding grain. Additionally a renewable energy source, hydropower doesn't emit any hazardous byproducts or pollute the environment. Discover more about the development of hydropower.

Farm &amp; ranch families account for roughly how much of the US population?
slavikrds [6]
<span>As of 2016, farm and ranch families made up only two percent of the total US population. The amount of farmer and ranching families has declined at a fast pace since it's peak in 1935. In the last twenty years most of the decline can be blamed on how little farmers and ranchers make from the food they grow or raise. Farmers and ranchers only receive, on average, sixteen cents for every dollar that is spent on food in both grocery stores, down from about thirty-one cents for every dollar in the 1980's.</span>

Samurai and Knight: were the similarities greater than the differences ​
Vlad1618 [11]

Answer:

There were more similarities than differences as both of them were members of military class, whose main obligation was to serve the ruler. They were both included in a system known to us as feudal system.

Explanation:

As we said both in Japan and Europe feudal system was functioning for a long period of time. They both had to participate in military campaigns when called upon by their ruler. Also, they both respected certain codes, known as bushido among samurais and code of chivalry. It is interesting that we have examples of samurai and knights being women.
