Final answer:
The Ring of Fire is named for its frequent earthquakes and volcanic activity, shaped by the movement of tectonic plates around the Pacific Ocean.
Therefore, the correct answer is: option D). because of many volcanoes
Step-by-step explanation:
The area known as the Ring of Fire is called this because it is a zone of frequent earthquake and volcanic activity.
This horseshoe-shaped line runs around the rim of the Pacific Ocean, where the movement of tectonic plates causes seismic activities, like the earthquakes along the San Andreas Fault, and volcanic events, such as the 1980 eruption of Mount St. Helens.
The Ring of Fire is a tectonic belt, about 40,000 km long and up to about 500 km wide, which circumscribes the Pacific Ocean. It contains between 750 and 915 volcanoes, around two-thirds of the world total, and 90% of the world's earthquakes, including 81% of its largest, take place within the belt.
The Ring of Fire has had a significant impact on the geology and history of regions like Japan, where tsunamis have also been a result of this tectonic activity.
