Responses
a It is an arc of intense seismic activity.
b It includes the northern edge of Alaska.
d It is a zone of frequent earthquakes.
c It is the result of plate tectonics.
b It includes the northern edge of Alaska.
The correct answer is option b: It includes the northern edge of Alaska.
To determine which statement is not true about the Pacific Ring of Fire, we can examine each option and assess its validity.
a) "It is an arc of intense seismic activity." - This statement is true. The Pacific Ring of Fire is indeed an arc characterized by a high level of seismic activity.
b) "It includes the northern edge of Alaska." - This statement is also true. The Pacific Ring of Fire stretches from the western coast of North and South America all the way to the eastern edge of Asia, including the northern edge of Alaska.
c) "It is the result of plate tectonics." - This statement is also true. The Pacific Ring of Fire is formed by the interaction of several tectonic plates, causing volcanic eruptions, earthquakes, and the formation of mountain ranges.
d) "It is a zone of frequent earthquakes." - This statement is true as well. The Pacific Ring of Fire experiences a high frequency of earthquakes, which is attributed to the active tectonic boundaries along its arc.
Therefore, the statement that is not true about the Pacific Ring of Fire is option b) "It includes the northern edge of Alaska."
