They are similar in the sense that both has a temporary effect om the solar disk which is called the photosphere. Also, both of these phenomenon exist due to the extreme magnetic energy that is created below the surface of the Sun. However, they are different in a number of ways. A sunspot would appear as a blotch that is dark on the photosphere since it has cooler temperature than the surroundings while solar flares exist as a very bright explosion of high amount of energy.

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.
Answer:
D) uniformitarianism; the geologic processes that operated in the past are the same as those that operate today, and they occurred in accordance with the same laws of nature that are operating today
Explanation:
When geologists conclude that the Grand Canyon sequence of rocks was formed through hundreds of millions of years of deposition, mountain building, and erosion, they are basing this conclusion on the principle of <u>uniformitarianism </u>which states that <u>the geologic processes that operated in the past are the same as those that operate today, and they occurred in accordance with the same laws of nature that are operating today</u>.
Uniformitarianism is a theory in geology which states that the changes in the earth's crust during geological history is as a result of actions of uniform and continuous processes, that the geological processes occurring currently are same processes that have been occurring in history and every part of the world and is continuous.
