Answer:
A Topographic maps is used to represent the Earths features.
Explanation:
Topographic maps are a detailed record of a land area, giving geographic positions and elevations for both natural and man made features. They show the shape of the land the mountains, valleys, and plains by means of brown contour lines (above sea level)
Answer: The reason this states have so many earthquakes is the fact of where they are located in the region of these states the earth surface has relatively thin crust and has high heat flow, both of which can favor relatively high deformation rates and active faulting. Unlike the opposite side of the states which has a colder much thicker crust which causes less fault formation and deformation of the crust.

i think maybe it's A not sure though
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.
