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.
Bacteria are required or needed in the nitrogen cycle because other living properties cannot use atmospheric nitrogen.
<h3>What is the nitrogen cycle?</h3>
The nitrogen cycle is the sequence of operations by which nitrogen and its mixtures are interconverted in the environment.
In living organisms, It considers nitrogen fixation and pollution.
As regards Nitrogen fixation is affected, just bacteria are competent to improve atmospheric nitrogen into structures usable by other living organisms.
In nitrogen fixation, the atomic nitrogen is converted into chemical forms functional by plants and convert atmospheric nitrogen into chemical forms functional by plants.
Therefore, option A is correct.
